Title:

PHOTOPOLYMERIZABLE RESIN COMPOSITION FOR OPTICAL RECORDING MEDIA AND OPTICAL RECORDING MEDIA

Document Type and Number:

WIPO Patent Application WO/2002/014386

Kind Code:

A1

Abstract:

Provided are a photopolymerizable resin composition which does not cause a metal closely adhering to the composition to suffer from chemical deterioration, and optical recording media made by using the composition. According to the present invention, a resin layer (35) of an optical recording medium (1) is formed by photo- polymerization of a photopolymerizable resin composition containing benzotriazole as an additive, so that even when the resin layer (35) is made to adhere closely to a first reflecting layer (15) comprising silver as the main component, the reflecting layer (15) dose not suffer from chemical deterioration.
