Abstract
The present invention relates to a thermally crosslinkable composition comprising an acid-modified polymer A having a melting point of 110 to 150° C. and a crystallization temperature of 50 to 90° C., an acid-modified polymer B having a melting point of 30 to 110° C. and a crystallization temperature of lower than 50° C., a tackifier resin, and a curing agent, wherein the thermally crosslinkable composition has a crystallization temperature of 30 to 70° C.
