ABSTRACT:
A hot-melt adhesive composition containing, (A) per 10 to 80 parts by weight of a base polymer, (B) 10 to 80 parts by weight of a stickiness-imparting agent which is a copolymer of a particular styrene-type monomer and a particular indene-type monomer, the molar ratio of the indene-type monomer to the styrene-type monomer being from 99/1 to 30/70, and the weight average molecular weight of said copolymer being from 300 to 5000. The hot-melt adhesive composition exhibits excellent heat-resistant adhesiveness and heat-resistant creeping property, and has a low-molecular weight and exhibits good hue.
