Abstract

(Problem) Provided is an aqueous painting material composition that does not undergo bleeding or dissolution of the paint film even when water droplets adhere to the dried paint film, and has resistance to wetting by water to such an extent that the base coat does not move even when overpainted on the paint film of a base coat, in the same way as conventional emulsion paints, that nevertheless can be removed by washing with water even when it has long been adhered to and dried on a palette or paint brush. (Solution) Provided is an aqueous painting material composition containing water, coloring pigment, and water-soluble resin and resin emulsion containing hydroxyalkyl cellulose and water-soluble styrene-acrylic resin, characterized in that the water-soluble styrene-acrylic resin is contained within a range of 0.5-6.5 wt% calculated for styrene-acrylic resin and the resin emulsion is contained within a range of from 0.1 wt% to less than 5 wt% in terms of solid content.

Description

technical field [0001] The present invention relates to a water-based painting material composition, which, like conventional emulsion painting materials, does not bleed or dissolve even if water droplets adhere to the coating film after the coating film dries, and even if it is recoated to The coating film of the base layer does not bleed or dissolve, that is, it has resistance to water wetting to the extent that the base layer does not change, so even if it is attached to a palette or a paintbrush and dried for a long time, It can also be removed by washing with water. Background technique [0002] In the past, the water-based painting material composition known as emulsion painting material has water as solvent, pigment as coloring agent, and resin emulsion as a kind of water-based painting material composition as fixing agent. If painting on the painting surface, After the coating film is formed, the solvent evaporates from the coating film and the coating film dries, a...
