Abstract

The curable composition of this invention comprises a grafted styrene elastomer obtained by grafting and modifying an aromatic vinyl monomer, and an unsaturated compound having two or more free radical polymerizable carbon-carbon unsaturated double bonds in one molecule. The aromatic vinyl monomer is represented by the following general formula (1). In the following general formula (1), R1, R2, R3, R4, R5, and R6 independently represent a hydrogen atom, a halogen atom, or an alkyl group having 1 to 6 carbon atoms. At least one of R2, R3, R4, R5, and R6 represents an alkyl group having 1 to 6 carbon atoms.
