<p>The coated article of the present invention relates to a coated article having excellent chemical resistance. More specifically, it relates to a coated article characterized in having a plastic base material and a coating film formed on the surface of the base material, the coating film being obtained from a resin composition containing a cellulose derivative, and in satisfying the relationship of formula (I): X - Y =ΔH≤grade 2 [in the formula, X is the pencil hardness before chemical treatment, Y is the pencil hardness after chemical treatment, andΔH is the grade difference in pencil hardness before and after chemical treatment; here, chemical treatment involves applying a sunscreen containing an ultraviolet absorber to the coating film surface of the coated article in a proportion of 2.0 g/100 cm2, then allowing it to stand for five hours at a temperature of 60±2°C, and the pencil hardness is measured in compliance with JIS K5600-5-4:1999 (ISO/DIS 15184:1996)].</p> |
