PHOTO-CURABLE ADHESIVE SHEET, PHOTO-CURABLE TRANSFER SHEET, OPTICAL INFORMATION RECORDING MEDIUM AND METHOD FOR PREPARING OPTICAL INFORMATION RECORDING MEDIUM |
摘要 |
<p>A method for preparing an optical information recording medium which comprises pressing two substrates for optical information recording having projections and depressions as recording pits and grooves via a photo-curable adhesive sheet which comprises a photo-curable composition containing a reactive polymer having a photo-polymerizable functional group and having a transition temperature of 20ringC, and exhibits a light transmissivity in a wavelength region of 380 to 420 nm of 70 % or more, and then subjecting the resultant laminated product to photo-curing; a method for preparing an optical information recording medium which comprises placing a photo-curable transfer sheet which comprises a photo-curable composition containing a reactive polymer having a photo-polymerizable functional group and being capable of deforming through the application of pressure, on the rugged surface of a substrate having projections and depressions as recording pits and grooves so as to contact with the rugged surface, pressing them to form a laminate wherein a surface of said photo-curable transfer sheet is closely attached along said rugged surface, and then curing the photo-curable transfer sheet of said laminate by the irradiation with an ultraviolet ray; and a photo-curable transfer sheet which comprises a photo-curable composition containing a reactive polymer having a photo-polymerizable functional group and being capable of deforming through the application of pressure and has a surface roughness (Ra) of at least one surface thereof of 30 nm or less.</p> |
