Abstract
The present invention relates to photopolymerizable resin composition inducing substantially no chemical degradation in metals in tight contract with the resin. Further, the present invention relates to optical recording media using the photopolymerizable resins. In one embodiment, a photopolymerizable resin composition includes a photopolymerizable resin based on acrylic ester, and an additive based on at least one selected from the group consisting of benzotriazole and a derivative of benzotriazole, and a photointiator.
Claims15
A photopolymerizable resin composition, comprising:
- a photopolymerizable resin based on acrylic ester;
- an additive based on at least one selected from the group consisting of
- 1,2,3-benzotriazole, methylbenzotriazole, 1-(N,N-bis(2-ethylhexyl)aminomethyl)benzotriazole, carboxybenzotriazole, and 3-(N-salicycloyl)amino-1,2,4-triazole;
- and
- a photoinitiator.
