Abstract
Provided is a coating composition containing a hydroxyl group-containing resin (A), a curing agent (B), a scale-shaped effect pigment (C), a viscosity modifier (D), and an organic solvent (E) having a solubility in water at 20° C. of 4 mass % or greater. The viscosity modifier (D) contains at least one viscosity modifier selected from the group consisting of a cellulose nanocrystal (D1) and a cellulose nanofiber (D2). A content of the organic solvent (E) having a solubility in water at 20° C. of 4 mass % or greater is in a range of 10 to 25 mass % based on a content of a volatile component in the coating composition.

A coating composition comprising:
- a hydroxyl group-containing resin (A);
- a curing agent (B);
- a scale-shaped effect pigment (C);
- a viscosity modifier (D);
- and
- an organic solvent (E) having a solubility in water at 20° C. of 4 mass % or greater,
- wherein the viscosity modifier (D) contains at least one viscosity modifier selected from the group consisting of a cellulose nanocrystal (D1) and a cellulose nanofiber (D2),
- wherein the organic solvent (E) includes one or more solvents selected from the group consisting of propylene glycol monobutyl ether, n-butanol, propylene glycol monomethyl ether, ethylene glycol monobutyl ether, and dipropylene glycol monomethyl ether, and
- wherein a content of the organic solvent (E) having a solubility in water at 20° C. of 4 mass % or greater is in a range from 10 to 25 mass % based on a total content of all volatile components in the coating composition.
