Abstract

A polyurethane resin composition comprising a polyurethane resin (U) and an organic solvent (S), wherein the polyurethane resin (U) has a structural unit derived from a polyoxyethylenediol (A), a structural unit derived from a polycarbonate diol (B), a structural unit derived from an aliphatic isocyanate compound (C), a structural unit derived from a C2-6 diol (D), and a structural unit derived from a C2-20 diamine (E), the structural unit derived from the aliphatic isocyanate compound (C) being either a structural unit derived from a non-cyclic aliphatic diisocyanate (c1) having a structure such that two isocyanate groups are directly bound to a non-cyclic hydrocarbon having an odd number of carbon atoms or a structural unit derived from an alicyclic diisocyanate (c2) in which the number of isocyanate groups that are directly bound to an alicyclic hydrocarbon is 0 or 1.
