Abstract: A thermoplastic resin composition (molding material) in which the problem that thermoplastic resins such as hydrogenated styrene polymers suffer a decrease in molecular weight upon melt molding and hence come to be mechanically brittle, is mitigated and which does not develop craze spots even when used in a high-temperature high-humidity atmosphere; and a substrate for optical recording media which comprises the composition. The thermoplastic resin composition comprises a thermoplastic polymer containing alicyclic groups and an addition-type stabilizer which can react by addition reaction with a free radical resulting from cleavage of the thermoplastic polymer.
