Embodiment

[0111] Hereinafter, the present invention will be described more specifically with reference to examples, but the present invention is not limited to these examples.

[0112] (optical system)

[0113] figure 1 Shown is a schematic diagram of the optical system used in the experiment. As a light source, a 532nm semiconductor laser is used, which is split into two beams by a beam splitter (BS) through a mirror (M), a spatial filter (OL and Ph), a plano-convex lens (PCL), and a wave blocking plate (PP). The two beams of light separated from the BS are incident on the sample at 30° and 30° respectively through the mirror and interfere. The intensities of diffracted light and transmitted light were detected using a power meter (PM: manufactured by ADC Corporation).

[0114] In addition, diffraction efficiency and shrinkage rate were calculated|required by the following method.

Embodiment X-1

[0128] Prepare 60 parts by weight of poly 2-vinylnaphthalene (Mw=93,000) as the binder polymer (A), which consists of a bifunctional alicyclic epoxy compound (3,4,3',4'-diepoxy Dicyclohexane) and bifunctional vinyl ether compound (oxanorbornene divinyl ether) mixed in a molar ratio of 7:1 cation polymerizable compound (B) 100 parts by weight, as photopolymerization initiator Diphenyl iodide of agent (C) 10 parts by weight of a compound (trade name "PI2074", manufactured by Rhodia Corporation) and 0.5 parts by weight of a coumarin-based pigment (trade name "NKX1658", manufactured by Hayashibara Biochemical Research Institute) as a sensitizing pigment (D), these The components were dissolved in 30 parts by weight of cyclohexanone, and the obtained solution was used as photosensitive liquid X-1. This photosensitive liquid X-1 was dropped onto a glass substrate, applied with a coater to a film thickness of 25 μm, and a frame with a thickness of 50 μm was provided on the surface ...

Embodiment X-2

[0130]Prepare 70 parts by weight of poly 2-vinylnaphthalene (Mw=93,000) as the binder polymer (A), which consists of a bifunctional cycloaliphatic epoxy compound (3,4,3',4'-diepoxy Dicyclohexane) and bifunctional vinyl ether compound (oxanorbornene divinyl ether) mixed in a molar ratio of 7:1 cation polymerizable compound (B) 100 parts by weight, as photopolymerization initiator Diphenyl iodide of agent (C) 10 parts by weight of a compound (trade name "PI2074", manufactured by Rhodia Corporation) and 0.5 parts by weight of a coumarin-based pigment (trade name "NKX1658", manufactured by Hayashibara Biochemical Research Institute) as a sensitizing pigment (D), these The components were dissolved in 280 parts by weight of cyclohexanone, and the obtained solution was used as photosensitive liquid X-2. This photosensitive solution X-2 was dropped onto a glass substrate, and applied using an applicator so that the film thickness after drying was 25 μm, and the solvent was sufficie...
