摘要

A self-repairing polyurethane resin material is produced by reaction of a polyisocyanate compound consisting of aliphatic polyisocyanate and/or araliphatic polyisocyanate with an active hydrogen group-containing compound, used for producing polyurethane resin having self-repairing properties, has an isocyanate group at its molecular terminal, contains an allophanate group and an isocyanate trimer, and the mole ratio of the allophanate group relative to the isocyanate trimer is 0.1 to 20.
