PROBLEM TO BE SOLVED: To obtain a shape memory and optical material which is transparent, can be arbitrarily deformed by heating and has shape memory properties, and to provide an optical part and a method for producing the optical part. SOLUTION: This shape memory and optical material is obtained by curing a curable resin composition containing a compound with two or more groups represented by formula (1) (X is CH2 , CH3 CH, (CH3 )2 C, O or S; R<1> is a hydrogen atom, an alkyl group, a carboxy group or its derivative; R<2> is a hydrogen atom, a cyano group, an alkyl group, a substituted alkyl group, a carboxy group or its derivative; n is an integer of 0-5; α is a binding site) and a compound with two or more thiol groups. |
