An optical information recording medium comprises a pair of substrates, with a recording layer comprising an organic dye being formed on one side of at least one substrate, fixed to each other through or without through a spacer and by an adhesive agent, in such a manner that the recording layer comes between the substrates, the adhesive agent comprising: (a) a compound of formula (I), <IMAGE> (I) wherein L1 represents <IMAGE> (m = 0 or 1, and n = 2 to 4), L2 represents <IMAGE> (m = 0 or 1, and n = 2 to 4), R1 represents a methyl group or an ethyl group, and k is an integer of 1 to 4; and (b) one compound of selected from the group consisting of: a compound of formula (II), <IMAGE> (II) wherein R2 represents hydrogen or a methyl group, and l is an integer of 3 to 15, a compound of formula (III), CH2=CHCOO-CH2)l'OCOCH=CH2 (III) wherein l' is an integer of 4 to 6, and a mixture of the two compounds. |
