Weiser et al. 20140295328 in example 11 (see table on page 14), combines polyol 1, isocyanate 1, two writing monomers, experimental additive 1, New Methylene Blue 0.10% with CGI 909 (product from BASF SE, Basle, Switzerland) 1.0%, as solution in N-ethylpyrrolidone (photoinitiator), and urethane catalyst dimethylbis[(1-oxoneodecl)oxy]stannane and Chain transfer agent 12 (3,6-dioxa-1,8-octadithiol, obtained from Sigma-Aldrich Chemie GmbH, Steinheim, Germany [0158]. To produce holographic media, the writing monomers B), the stabilizers, which might already have been predissolved in component B), and also optionally the auxiliary and admixture agents were dissolved in the employed polyol (isocyanate-reactive component b)) optionally at 60.degree. C. and thoroughly mixed. Thereafter, in the dark or under suitable illumination, the photoinitiator(s) C) and also the chain transfer agent(s) E) was/were weighed in and again mixed in for one minute to obtain a clear solution. Then, the isocyanate component a) was added which was again followed by mixing for 1 minute. The liquid mass obtained was then applied to substrate foil 1 and dried at 80.degree. C. for 4.5 minutes. Dry layer thickness was determined [0211]. To measure the holographic performance of the holographic film, the protective foil is peeled off and the holographic film is laminated with the photopolymer side onto a 1 mm thick glass plate of suitable length and width by applying a rubber roll under light pressure. This sandwich of glass and photopolymer foil can then be used to determine the holograph performance parameters DE and .DELTA.n. The beam of an He--Ne laser (emission wavelength 633 nm) was transformed via the spatial filter (SF) and together with the collimation lens (CL) into a parallel homogeneous beam. The final cross sections of the signal and reference beams are fixed via the iris diaphragms (I). The diameter of the iris diaphragm opening is 0.4 cm. The polarization-dependent beam splitters (PBS) split the laser beam into two coherent identically polarized beams. Via the .lamda./2 plates, the power of the reference beam was adjusted to 0.5 mW and the power of the signal beam to 0.65 mW. The powers were determined using the semiconductor detectors (D) with sample removed. The angle of incidence (.alpha..sub.0) of the reference beam is -21.8.degree. and the angle of incidence (.beta..sub.0) of the signal beam is 41.8.degree.. The angles are measured from the sample normal to the beam direction. According to FIG. 1, therefore, .alpha..sub.0 has a negative sign and .beta..sub.0 has a positive sign. At the location of the sample (medium), the interference field of the two overlapping beams produced a grating of light and dark strips which are perpendicular to the angle bisector of the two beams incident on the samples (reflection hologram). The strip spacing .LAMBDA., also referred to as grating period, in the medium is .about.225 nm (the refractive index of the medium is assumed to be .about.1.504) [0176-0177].

Production of photosensitive substrate for volume hologram recording The photosensitive composition 1 for volume hologram recording obtained in (1) is placed on a 50 μm polyethylene terephthalate (PET) film (Toray Lumirror T-60). Using an applicator, coating and drying were carried out so that the film thickness after drying was 10 μm to obtain a hologram recording layer, whereby a volume type hologram recording photosensitive substrate 1 of Example 1 was obtained. (3) Manufacture of volume hologram recording body The hologram recording layer side of the volume hologram recording photosensitive substrate of Example 1 obtained in (2) is laminated on a mirror, and PET of the volume hologram recording photosensitive substrate is obtained. A 532 nm laser beam was incident from 10 to 100 mJ / cm .sup.2 from the side, interference exposure was performed, and a volume hologram was recorded. At that time, the incident angle of the laser beam to the hologram recording layer was an angle of 0 degrees of the hologram. After recording, the photosensitive substrate for volume hologram recording was peeled off from the mirror, and a 38 μm polyethylene terephthalate (PET) film (A4300; manufactured by Toyobo Co., Ltd.) was laminated on the hologram recording layer side. Next, heating at 80 ° C. for 30 minutes, irradiating the entire surface with ultraviolet rays, fixing the hologram recording layer, further irradiating green light near 530 nm for 100 minutes, decolorizing the sensitizing dye, and hologram having interference fringes recorded A volume hologram recording body 1 of Example 1 having a layer was obtained [0097-0099].

Part. In such a range, the reaction rate of the photo-radically polymerizable monomer can be increased to such an extent that the movement of the monomer is not inhibited, so that the sensitivity during hologram recording and the refractive index modulation amount (Δn) at a low exposure amount are high. A photosensitive composition for volume hologram recording can be obtained. Moreover, since it is the optimal addition amount which does not inhibit the decolorization of a sensitizing dye, the photosensitive composition for volume type hologram recording with the favorable decoloring property of a sensitizing dye can be obtained [0023-0034]. As the radical photopolymerizable monomer used in the present invention, when a hologram recording layer is formed using the photosensitive composition for volume hologram recording of the present invention, a radical photopolymerization initiator described later, for example, by laser irradiation or the like. Although it will not specifically limit if it is a compound polymerized by the action of the active radical generated from, it is preferable to use a compound having at least one ethylenically unsaturated double bond in the molecule. For example, unsaturated carboxylic acid, unsaturated carboxylate, ester of unsaturated carboxylic acid and aliphatic polyhydric alcohol compound, amide bond of unsaturated carboxylic acid and aliphatic polyhydric amine compound, etc. can be mentioned [0036].

Claims 1,2,5,7-9,13,14,16,18-21 are rejected under 35 U.S.C. 103 as being unpatentable over Sasaki et al. JP 2008268520, in view of Alim et al. WO 2019237117, Kosaka 20030194487, Weiser et al. 20140295328 and Hamaide et al. JP 2014-044242 and further in view of Stockel et al. 20090062419.
Stockel et al. 20090062419 exemplifies poly (.epsilon.-caprolactone)-block-poly(tetrahydrofuran)-block-poly(.epsilon.-caprolactone)polyols in block copolymers B and C [0083-0084]. These are used in holographic polyurethane formation C and D [0088-0089].
Esters of acrylic acid or methacrylic acid are generally referred to as acrylates or methacrylates. Examples of acrylates and methacrylates which may be used are methyl acrylate, methyl methacrylate, ethyl acrylate, ethyl methacrylate, ethoxyethyl acrylate, ethoxyethyl methacrylate, n-butyl acrylate, n-butyl methacrylate, tert-butyl acrylate, tert-butyl methacrylate, hexyl acrylate, hexyl methacrylate, 2-ethylhexyl acrylate, 2-ethylhexyl methacrylate, butoxyethyl acrylate, butoxyethyl methacrylate, lauryl acrylate, lauryl methacrylate, isobornyl acrylate, isobornyl methacrylate, phenyl acrylate, phenyl methacrylate, p-chlorophenyl acrylate, p-chlorophenyl methacrylate, p-bromophenyl acrylate, p-bromophenyl methacrylate, trichlorophenyl acrylate, trichlorophenyl methacrylate, tribromophenyl acrylate, tribromophenyl methacrylate, pentachlorophenyl acrylate, pentachlorophenyl methacrylate, pentabromophenyl acrylate, pentabromophenyl methacrylate, pentabromobenzyl acrylate, pentabromobenzyl methacrylate, phenoxyethyl acrylate, phenoxyethyl methacrylate, phenoxyethoxyethyl acrylate, phenoxyethoxyethyl methacrylate, 2-naphthyl acrylate, 2-naphthyl methacrylate, 1,4-bis-(2-thionaphthyl)-2-butyl acrylate, 1,4-bis-(2-thionaphthyl)-2-butyl methacrylate, bisphenol A diacrylate, bisphenol A dimethacrylate, tetrabromobisphenol A diacrylate, tetrabromobisphenol A dimethacrylate, 2,2,2-trifluoroethyl acrylate, 2,2,2-trifluoroethyl methacrylate, 1,1,1,3,3,3-hexafluoroisopropyl acrylate, 1,1,1,3,3,3-hexafluoroisopropyl methacrylate, 2,2,3,3,3-pentafluoropropyl acrylate and/or 2,2,3,3,3-pentafluoropropyl methacrylate. Epoxy acrylates also suitable as component C) can be obtained as reaction products of bisphenol A diglycidyl ether with hydroxyalkyl (meth)acrylates and carboxylic acids, the bisphenol A diglycidyl ether first being reacted with hydroxyalkyl (meth)acrylate with catalysis by Lewis acid and this hydroxyl-functional reaction product then being esterified with a carboxylic acid by a method known to the person skilled in the alt. Bisphenol A diglycidyl ether itself and brominated variants, such as, for example, tetrabromobisphenol A diglycidyl ether (from Dow Chemical, D.E.R. 542), can advantageously be used as the diepoxide. All hydroxyl-functional acrylates described above can be used as hydroxyalkyl (meth)acrylates, in particular 2-hydroxyethyl acrylate, hydroxypropyl acrylate, 4-hydroxybutyl acrylate, poly(.epsilon.-caprolactone) mono (meth)acrylates and poly(ethylene glycol) mono(meth)acrylates. All monofunctional carboxylic acids are in principle suitable as the carboxylic acid, in particular those having aromatic substituents. Propane-2,2-diylbis[(2,6-dibromo-4,1-phenylene)oxy(2-{[3,3,3-tris(4-chlor- ophenyl)propanoyl]oxy}propane-3,1-diyl)oxyethane-2,1-diyl]diacrylate has proved to be a preferred compound of this class of epoxy acrylates. Vinylaromatics suitable for component C) are styrene, halogenated derivatives of styrene, such as, for example, 2-chlorostyrene, 3-chlorostyrene, 4-chlorostyrene, 2-bromostyrene, 3-bromostyrene, 4-bromostyrene, p-(chloromethyl)styrene, p-(bromomethyl)styrene or 1-vinylnaphthalene, 2-vinylnaphthalene, 2-vinylanthracene, N-vinylpyrrolidone, 9-vinylanthracene, 9-vinylcarbazole or difunctional compounds, such as divinylbenzene. Vinyl ethers, such as, for example, butyl vinyl ether, are also suitable [0048-0049]
