Photo-curable transfer sheet, laminate optical information recording substrate, method for manufacture thereof, and optical information recording medium

摘要

A photo-curable transfer sheet having a photo-curable layer comprising a photo-curable composition, the photo-curable composition being deformable by application of pressure and containing a reactive polymer having a photopolymerizable functional group. The photo-curable transfer sheet preferably has a light transmittance of not less than 70% in a wavelength rang of 380 to 420 nm. An optical information recording substrate and medium prepared by the sheet. The sheet easily and precisely enables transfer of unevenness of the surface of a stamper by pressing.
