Abstract
An antibacterial/antiviral coating material is provided, which allows for forming a highly water-resistant antibacterial/antiviral coating film. The antibacterial/antiviral coating material is obtained by blending, into an acrylic-melamine resin coating material, a quaternary ammonium salt (A) represented by Formula (1) below, and a polyhydric carboxylic acid (B) having a C6 or more hydrocarbon group and two or more carboxyl groups. (In Formula (1), R1 represents a C8-22 alkyl group; R2A, R2B and R2C each independently represent a C1-3 alkyl group; and X represents a halogen atom).
