Beschreibung
Zusammenfassung:	This reactive hot-melt adhesive contains a urethane prepolymer and satisfies at least one of the following condition A or condition B.　Condition A: the proportion of aromatic rings in the total amount of the urethane prepolymer is 22 mass% or less. Condition B: the glass transition temperature in a cured state is 25 °C or less. Cet adhésif thermofusible réactif contient un prépolymère d'uréthane et satisfait à la condition A et/ou à la condition B suivante(s). Condition A : la proportion de cycles aromatiques dans la quantité totale du prépolymère d'uréthane est inférieure ou égale à 22 % en masse. Condition B : la température de transition vitreuse dans un état durci est inférieure ou égale à 25 °C. ウレタンプレポリマーを含み、下記条件Ａ又は条件Ｂの少なくともいずれかを満たす、反応性ホットメルト接着剤。　条件Ａ：ウレタンプレポリマー全量に占める芳香環の割合が２２質量％以下である　条件Ｂ：硬化状態でのガラス転移温度が２５℃以下である
