## Abstract

The present application discloses a polyol composition for a polyurethane resin and a polyurethane-resin-formable composition that are capable of forming a polyurethane resin that exhibits a low resin viscosity during shaping, but has a high glass transition temperature, and a composite material. A polyol composition for a polyurethane resin includes an esterified compound (A) having an average esterification degree of 0.5 to 2.5, wherein the esterified compound (A) includes, as constituent components, a triol (a1) and a fatty acid (a2) having 2 to 18 carbon atoms.
