Thermosensitive adhesive material

摘要

A thermosensitive adhesive material which is superior in blocking resistance when not active and which has adequate adhesion in a wide temperature range to a target with little smoothness such as corrugated fiberboard. Specifically, the thermosensitive adhesive material includes a support, and a thermosensitive adhesive layer provided on one surface of the support, the thermosensitive adhesive layer containing as essential components a thermoplastic resin and a hot-melt material that melts when heated, wherein the thermoplastic resin contains as a main component a (meth)acrylic copolymer in which acrylonitrile, a monomer component, occupies 5% by mass to 20% by mass of all monomer components, and wherein the glass transition temperature of the copolymer is in the range of -70°C to -30°C.
