Provided is an adhesive as follows. The adhesive can bond/secure an adherend to a support with maintaining high adhesiveness during the existence of the need for securing of the adherend to the support, even in a high-temperature environment or in an environment with abrupt temperature change. The adhesive enables debonding of the adherend from the support without breakage of the adherend when the securing becomes unnecessary. The adhesive can be easily removed when remained on the adherend after debonding. The adhesive according to the present invention contains (A) a multivalent vinyl ether compound, (B) a compound including two or more of a constitutional unit represented by Formula (b), and (C) a thermoplastic resin. In the formula, X is selected from hydroxy and carboxy.
本文提供了一种粘合剂。该粘合剂即使在高温环境或温度骤变的环境中,也能在需要将附着物固定到支撑物上的过程中保持高粘合力,将附着物粘合/固定到支撑物上。当不需要固定时,粘合剂可使粘附物与支撑物脱开,而不会导致粘附物破损。粘合剂在脱粘后残留在被粘物上时可以很容易地去除。根据本发明的粘合剂含有 (A) 多价乙烯基醚化合物,(B) 包括两个或两个以上由式 (b) 代表的构型单元的化合物,以及 (C) 热塑性树脂。式中,X 选自羟基和羧基。
