Polyurethane-resin-forming composition, and film sealing material and film module each obtained using said polyurethane- resin-forming composition

Abstract

A polyurethane-resin-forming composition including a polyisocyanate prepolymer (A) and a polyol (B) is disclosed. The polyisocyanate prepolymer (A) contains a reaction product of diphenylmethane diisocyanate (a1-1) and/or modified diphenylmethane diisocyanate (a1-2), and an active hydrogen-containing compound (a2), the polyol (B) includes a transesterification product (b1) of a castor oil-based polyol and a hydroxyl group-containing amine-based compound, a hydroxyl group-containing amine-based compound (b2), and a castor oil-based polyol (b3), a content of the transesterification product (b1) is 0.1 mass % or more and 10 mass % or less with respect to a total mass of the polyisocyanate prepolymer (A) and the polyol (B).
