A hot melt adhesive composition, comprising a blend of components including about 5% to about 50% by weight of an olefin block copolymer； about 10% to about 70% by weight of a first tackifying resin having a softening point of at least about 95° C.； about 0 to 65% of a second tackifying resin that is different than the first tackifying resin； about 0% to about 60% by weight of a plasticizer； about 0% to about 20% by weight of an aromatic reinforcing resin having a softening point equal to or higher than 115° C.； about 0.1% to about 5% by weight of a stabilizer； and about 1% to about 40% by weight of a secondary polymer that is different from the olefin block copolymer, the first and second tackifying resins and the reinforcing resin, having relatively low crystallinity, which low crystallinity is equal to or less than 250 Joules/gram, wherein the components total 100% by weight of the composition, and the viscosity of the composition is equal to or less than about 20,000 mPa·s at 163° C. Laminates, especially those used in disposable soft goods, and methods of making such laminates using the hot melt adhesive composition are also described. The adhesive composition and/or laminate may be used in making a variety of end products such as a disposable diaper, a sanitary napkin, a bed pad, a bandage, a surgical drape, a tape, a label, a plastic sheet, a nonwoven sheet, a paper sheet, a cardboard, a book, a filter, or a package.約５～５０重量％のオレフィンブロックコポリマー、約１０～７０重量％の第１粘着付与樹脂、約０～６５％の第２粘着付与樹脂、約０～６０重量％の可塑剤；約０～２０重量％の芳香族強化樹脂、約０．１～５％の安定剤、および約１～４０重量％の二次ポリマーを含む構成要素のブレンドにおいて、第１および第２粘着付与樹脂ならびに強化樹脂が、２５０ジュール／グラム以下の結晶化度を有する、該ブレンドを含むホットメルト接着剤組成物であって、構成要素は合計で組成物の１００重量％となり、組成物の粘度は、１６３℃で約２０，０００ｍＰａ．ｓ以下である、組成物。該ホットメルト接着剤を用いた積層体ならびにかかる積層体を作製する方法も記載されている。接着剤組成物および／または積層体は、種々の最終製品において用いられ得る。
