摘要

PPROBLEM TO BE SOLVED: To provide a composition which can give a flexible resinous molded body having together the flexibility and heat resistance and also having the excellent pressure-sensitive adhesion and under-shear adhesive performance at high temperatures. PSOLUTION: The composition for a flexible resinous molded body contains A: a solventless type of an acrylic-based copolymer containing a hydroxy group as a functional group of on the average from not less than 2.2 to not more than 2.7 per one molecule and having a number-average molecular weight of 8,000-30,000 and the fluidity at normal temperatures, B: a solventless type of an acrylic-based copolymer containing a hydroxy group as a functional group of on the average from not less than 1.3 to not more than 2.1 per one molecule and having a number-average molecular weight of 2,000-7,000 and the fluidity at normal temperatures, and C: a liquid isocyanate compound containing an isocyanate group as a functional group and having the fluidity at normal temperatures; and the flexible resinous molded body is obtained by curing the composition.
