Abstract

The present invention uses a urethane resin composition including a urethane resin (A), a multifunctional acrylate (B), and a solvent (C). The urethane resin (A) is a reaction product of a polyol (a1) and a polyisocyanate (a2). The polyol (a1) includes an alkylene diol (a1-1) having two or more polymerizable unsaturated groups and represented by general formula (1) or an oxyalkylene diol (a1-2) having two or more polymerizable unsaturated groups and represented by general formula (2) below. The proportion of polymerizable unsaturated bonds in the urethane resin composition is within a range of 3 to 9 mmol/g. The urethane resin composition is a urethane resin composition that can form a coating film having excellent hardness, scratch resistance, and flexibility.HO—R—OH  (1)HO—RO—R—OR—OH  (2)
