(57) [Summary]na) about 15 to about 40% by weight of a block copolymer having a coupling ratio of about 75% or less; and b) a tackifying resin selected from the group consisting of a tackifying resin having a softening point of about 100 ° C. or less. 20 to about 50% by weight, c) about 30 to about 50% by weight of plasticizing oil, and d) up to about 15% by weight of a compatible polymer, the total polymer content not exceeding 40% by weight of the adhesive. It is a melt pressure sensitive adhesive, and this hot melt pressure sensitive adhesive fails to coagulate during use. |
