Self-repairing polyurethane resin material, self-repairing polyurethane resin, self-repairing coating material, self-repairing elastomer material, method for producing self-repairing polyurethane resin material, and method for producing self-repairing polyurethane resin

A self-repairing polyurethane resin material used for producing polyurethane resin having self-repairing properties,

• wherein the self-repairing polyurethane resin material has an isocyanate group at its molecular terminal,
• the self-repairing polyurethane resin material is produced by the reaction of a polyisocyanate compound consisting of aliphatic polyisocyanate and/or araliphatic polyisocyanate and an active hydrogen group-containing compound,
• an allophanate group and an isocyanate trimer are contained, and
• the mole ratio of the allophanate group relative to the isocyanate trimer is 0.1 to 20.
