发明名称 INFORMATION RECORDING MEDIUM
摘要 PURPOSE:To improve sealing reliability by providing a specific sealing structure to the titled medium and incorporating the cured body of a specific compd. into an adhesive agent layer. CONSTITUTION:This recording medium has the sealing structure formed by sticking a pair of plastic substrates 1, 1 having a recording layer 3 on one face of at least a sheet of the two substrates 1 to each other by means of the adhesive agent layer 7 via or without via spacers 4, 5 in such a manner that the recording layer 3 is positioned on the inside. The adhesive agent layer 7 contains the cured body of the compd. expressed by following formula: In formula, R1-R3 denote CH2=CH-, CH2=CHCOOCH2CH2-, HOCH2CH2-, CnH2n+1- (n=1-4), etc., at least one of which is an unsatd. bond-contg. group. The sealing reliability is thereby improved.
