Abstract
From the point of view of the necessity for coating films with superior adhesion to substrates, there is demand for the development of new resin compositions. The abovementioned problem is solved by the resin composition described below. Specifically, provided is a resin composition containing a polycarbonate resin, an active methylene-based block polyisocyanate, and an amine-based catalyst, wherein the polycarbonate resin includes a terminal structure (A) represented by general formula (1) and a constituent unit (B) derived from a monomer represented by general formula (2). R1 to R7, Z, a, X, Y, and * in formulas (1) and (2) are as described in the specification.
