PHOTOCURABLE RESIN COMPOSITION FOR PHOTORECORDING DISK

摘要

PROBLEM TO BE SOLVED: To provide a material excellent in transparency which does not absorpe light in a wavelength range of 380-800 nm and has a excellent molding property and functions as an adhesive agent which adheres a transparent substrate on the both faces in a multilayer disk. SOLUTION: The multilayer photorecording disk, is provided to solve the problem by using photocurable resin composition having (A) a cation polymerizable monomer, (B) a cation polymerizable copolymer whose glass transition point is 20 deg.C or less and (C) a photoinitiator.
