CURABLE RESIN COMPOSITION FOR OPTICAL RECORDING MEDIUM, CURED PRODUCT AND OPTICAL RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide an curable resin composition for optical recording media capable of giving a cured product which sufficiently exhibits various properties such as transparency and film thickness-stability, stably inhibits warpage and permanent deformation over a long period, and furthermore has excellent surface smoothness, and enables achieving recoding/reproduction with higher reliability, and a cured product thereof, and an optical recording medium having a layer obtained by curing this resin composition.

SOLUTION: The curable resin composition for optical recording media is a curable resin composition to be used in optical media for performing recording and/or reproduction with blue laser beams and includes an alkylene oxide and/or ε-caprolactone-modified tri- or higher functional (meth)acrylate compound, an alkylene oxide and/or ε-caprolactone-modified bifunctional (meth)acrylate compound, a specific (meth)acrylate compound having two or more radically polymerizable unsaturated groups in the molecule, and a photopolymerization initiator.
