Abstract: It is an object of the present invention to fix a silane-based coating in a highly durable state on a resinous base. A coating material for a primer fixes a silane-based coating on a resinous base. The coating material contains a polyacrylic acid, and an alkoxysilane having two or more alkoxy groups in its molecule and/or a hydrolysis product thereof. The use of the coating material for a primer of the present invention makes it possible to form a coating for imparting an effect of suppressing slime deposition on the resinous base.

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).

Abstract: A highly hot-water-resistant antibacterial treatment agent is provided, which is capable of suppressing the sliminess of water supply-and-drainage members such as drainage members, for a long period of time, equipped to a kitchen sink or bathroom drain. The antibacterial treatment agent includes: a quaternary ammonium salt represented by Formula (1) below; and a polyhydric carboxylic acid having a C6 or higher hydrocarbon group and two or more carboxyl groups. (In Formula (1), R1 represents a C16-18 alkyl group; R2A, R2B, R4A, R4B and R4C each independently represent a C1-3 alkyl group; R3 represents a C1-4 alkylene group; and X represents a halogen atom).
