Claim 0:
1. A hot melt adhesive comprising: (A) a metallocene based propylene homopolymer, (B) a metallocene based ethylene/α-olefin copolymer, (C) a tackifier resin, and (D) a plasticizer,
wherein the amount of the (A) metallocene based propylene homopolymer ranges from 15 to 45 parts by weight, based on 100 parts by weight of the total weight of the (A) metallocene based propylene homopolymer and the (B) metallocene based ethylene/α-olefin copolymer;
wherein the plasticizer (D) consists of (D1) an oil having a weight average molecular weight of 200 to 1,000 and (D2) at least one polymer having a weight average molecular weight of 2,000 to 100,000 selected from polybutene, polybutadiene, and polyisobutylene and the (D2) at least one polymer is present in an amount of 15 to 55 parts by weight, based on 100 parts by weight of the total weight of the plasticizer (D); and
wherein the hot melt adhesive is a pressure sensitive adhesive.
