Water-based resin for paints, coated paints, pen-shaped application tools filled with this paint, and film formed from this paint

Abstract

The term "water-based resin" refers to a water-based resin formulation that allows for the formation of highly designable films. Here, (A) refers to the resin component, (A1) acrylic resin emulsion, (A2) polyester resin emulsion, and (B) black material, which is a complex of (B1) black pigment with a particle diameter of 2 µm or larger and 6 µm or smaller and resin. The invention consists of at least (A) and (B), where (A) consists of 90% or more by mass of (Al) and (A2), and the mass ratio of the solid content of the resin in (A2) to the solid content of the resin in (Al):l is 1.8 or greater and 4.4 or less; (B) consists of 90% or more by mass of (B1); and the mass ratio of (B) to the solid content of the resin in (Λ):l is 1.3 or greater and 4.0 or less.
