Abstract: The present invention provides a urethane resin composition containing a urethane resin having polymerizable unsaturated groups and an aqueous medium. The urethane resin is obtained by reacting a polyol with a polyisocyanate. The polyol contains an alkylenediol having two or more polymerizable unsaturated groups or an oxyalkylenediol having two or more polymerizable unsaturated groups. The alkylenediol is represented by general formula (1): HO—R1—OH  (1) (where R1 is a linear alkylene group of one to nine carbon atoms having two or more atomic groups containing a polymerizable unsaturated group in side chains thereof). The oxyalkylenediol (a1-2) is represented by general formula (2): HO—R1O—R2—OR3—OH  (2) (where R1 and R3 are ethylene groups having a total of two or more atomic groups containing a polymerizable unsaturated group in side chains thereof, and R2 is an alkylene group of one to five carbon atoms). This urethane resin composition can form a coating with good elongation and flexibility and high hardness.
