PROBLEM TO BE SOLVED: To provide a coating agent composition which imparts excellent weather resistance, its persistence, and transparency to a sheet, and to provide a sheet having a protective layer formed of the composition.SOLUTION: The coating agent composition contains a caprolactone-based urethane (meth)acrylate, a triazine-based ultraviolet absorber, and a hindered amine-based light stabilizer which has a functional group having an ethylenic double bond. The content of the triazine-based ultraviolet absorber is 3-10 pts.mass based on 100 pts.mass of the caprolactone-based urethane (meth)acrylate. A sheet 1 has a surface protective layer 6 formed by crosslinking and curing the coating agent composition. The coating agent composition further contains a silicate compound having an ethylenic double bond, or an alkyl silicate.SELECTED DRAWING: Figure 1 |
