PURPOSE:To provide optical information recording medium having the sticking structure which enhances the adhesive strength between replica substrates and adhesive layers and has excellent peeling resistance. CONSTITUTION:The replica substrates 1 are stuck to each other via the adhesive layers 5 added with a silane coupling agent or titanium coupling agent. This method is applicable to either of an air sandwich structure and a tight sticking structure. The good peeling resistance is obtd. if inorg. fillers subjected to a surface treatment with the silane coupling agent or titanium coupling agent are added into the adhesive layer 5 in the case of addition of the inorg. fillers into the adhesive layer 5. |
