Title:
自己修復性ウレタン（メタ）アクリルアミド及びそれを含有する樹脂組成物
Document Type and Number:
Japanese Patent JP7391365
Kind Code:
B2
Abstract:
To provide a resin composition for self-repairable material which is excellent in curability with active energy rays, and is excellent in self repair property, stain resistance, bending resistance, flexibility and strength.SOLUTION: Urethane (meth)acrylamide capable of providing a cured product having a loss elastic modulus in a specific range is excellent in self repair property, stain resistance and the like. The urethane (meth)acrylamide is composed of polyisocyanate, low-molecular-weight polyol, (meth)acrylamide having a hydroxyl group and (meth)acrylate having a hydroxyl group, a content of the hard segment is 20-70 mass%, and a resin composition for self repair material can form a cured product that has high curability to active energy rays and has excellent self repair property, stain resistance and bending resistance by containing the urethane (meth)acrylamide.
