PURPOSE:To obtain the optical information recording medium which is enhanced in the adhesiveness between an underlying layer and a transfer layer, is im proved in pit length accuracy and has high reliability by using nitrocellulose as an org. compd. which forms the transfer layer and using a UV curing resin having the good adhesiveness to the underlying layer as the underlying layer. CONSTITUTION:This recording medium is constituted of a transparent substrate 4, the underlying layer 5, a transfer layer 6, a recording layer 7, pregrooves 8, prepits 9, and a silane coupling agent layer 11. The org. compd. forming the transfer layer 6 is the nitrocellulose. The UV curing resin, such as, for example, tetrahydrofurfuryl acrylate, having the good adhesiveness to the nitrocellulose, is used for the underlying layer 5. The optical information recording medium which has the high strength of adhesion between the underlying layer 5 and the transfer layer 6, obviates the peeling from both boundaries and has the good pit length accuracy and high reliability is obtd. in this way. |
