COMPOSITION, ADHESIVE, ADHESIVE SHEET, AND LAMINATE

摘要

PROBLEM TO BE SOLVED: To provide an adhesive and an adhesive sheet capable of strongly bonding a rubber member, particularly a vulcanized rubber member, and to provide a laminate formed by bonding a rubber layer using at least one of the adhesive and the adhesive sheet.SOLUTION: A composition is obtained by blending a polythiol compound (A), an isocyanate group-containing compound (B), and a radical generator (C). The ratio (isocyanate groups/thiol groups) of the total number of moles of isocyanate groups contained in the isocyanate group-containing compound (B) to the total number of moles of thiol groups contained in the polythiol compound (A) is 0.2 to 0.78 (inclusive).
