For improving the humidity resistance reliability and the jitter property
of an optical disk, the adhesive layer used for bonding a bonding type
optical information recording medium is defined such that the glass
transition temperature is 100.degree. C. or higher at 200.degree. C. or
lower, the modulus of elasticity at 25 to 80.degree. C. is 1000 MPa or
more, the adhesion strength thereof is 4 N or more, the reflective layer
is defined such that the hardness is 60 mgf/.mu.m.sup.2 or more as the
nano indentation hardness, and the dye recording layer is defined such
that the water solubility of the dye as light absorption is 0.2 or less.
