PURPOSE: The titled composition that contains a polymer having amino groups as side chains, a photoreductive pigment having an absorption band in the visible zone and a polymerizable unsaturated monomer, thus showing good compatibility, curing with visible rays and being used as a material for hologram recorder, because of its high sensitivity.
CONSTITUTION: The objective resin composition comprises (A) a polymer having groups of the formula [X is -COO-, -O-; Y is -CH2CH(OH)CH2-; R1, R2 are alkyl or bind with each other to form alkylene] such as a polymer resulting from addition of diethanolamine to a copolymer containing glycidyl methacrylate, (B) a photoreductive pigment having an absorption band in the visible zone such as methylene blue and (C) a polymerizable monomer having unsaturated groups such as pentaerythritol tetraacrylate.
