Zusammenfassung:To provide an adhesive for a vinyl chloride resin capable of efficiently and firmly bonding an article composed of a vinyl chloride resin and other articles.SOLUTION: There is provided an adhesive for a vinyl chloride resin which is an adhesive for bonding a member composed of a vinyl chloride resin and a resin sheet and comprises (A) a moisture curing type urethane prepolymer having an isocyanate group in the terminal which is a reaction product of a polyisocyanate compound having at least two or more isocyanate groups in the molecule and a polyol compound having at least two or more hydroxyl groups in the molecule in which the mass of the isocyanate group is 0.015 to 0.10 g per 1 g of the reaction product and (B) an organic solvent having no active hydrogen.SELECTED DRAWING: None 【課題】塩化ビニル樹脂からなる物品とその他の物品とを、効率よく、強固に接着できる塩化ビニル樹脂用接着剤を提供することにある。【解決手段】本発明に係る塩化ビニル樹脂用接着剤は、塩化ビニル樹脂からなる部材と樹脂シートとを接合するための接着剤であって、(A)分子内にイソシアネート基を少なくとも2つ以上含むポリイソシアネート化合物と、分子内に水酸基を少なくとも2つ以上含むポリオール化合物との反応物であり、末端にイソシアネート基を有し、かつ該反応物1g当たり、該イソシアネート基の質量が0.015〜0.10gである湿気硬化型ウレタンプレポリマー、及び(B)活性水素を有さない有機溶媒を含んでなることを特徴としている。【選択図】 なし
