Adhesive

Abstract

Abstract PURPOSE:To provide a hot-melt adhesive comprising a thermoplastic copolyester with specified composition, limited viscosity and softening point and exhibiting excellent adhesion to polyvinyl chloride, polyester, etc. CONSTITUTION:The adhesive consists of (A) acid component containing 30- 90mol% aromatic dicarboxylic acid in which terephthalic acid accounts for 50mol% or higher, 5-50mol% aliphatic hydroxycarboxylic acid (e.g. epsilon-caprolactone) and 0-20mol% aliphatic dicarboxylic acid (e.g. adipic acid) and (B) alcohol component which contains at least 90mol% 2-6C aliphatic glycol (e.g. 1,4- butanediol), and has a limiting viscosity number of 0.4-10dl/g and a softening point of 70-180 deg.C.
