Effect pigment-containing, water-borne base coating compositions |
摘要 |
This invention provides an effect pigment-containing, water-borne base coating composition comprising water-dispersible acrylic polymer particles (A) and effect pigment (B), the water-dispersible acrylic polymer particles (A) being obtained by emulsion polymerization of a radical-polymerizable unsaturated monomeric mixture including an amido-containing, radical-polymerizable unsaturated monomer having at least two radical-polymerizable unsaturated groups per molecule, and the effect pigment (B) being contained at a pigment weight concentration (PWC) within a range of 15-50%. |

1. An effect pigment-containing, water-borne base coating composition comprising water-dispersible acrylic polymer particles (A) and an effect pigment (B) which imparts to a coating film glittering brilliance or interference of light rays, and which is flaky or laminar, the water-dispersible acrylic polymer particles (A) being obtained by emulsion polymerization of a radical-polymerizable unsaturated monomer mixture comprising an amido-containing radical-polymerizable unsaturated monomer (M-1) having at least two radical-polymerizable unsaturated groups per molecule, a carboxyl-containing radical-polymerizable unsaturated monomer (M-2-1) and a hydroxyl-containing radical-polymerizable unsaturated monomer (M-2-2), in the presence of a reactive emulsifying agent which is an ammonium salt of a sulfonic acid compound having radical-polymerizable unsaturated groups, and the effect pigment (B) being contained at a pigment weight concentration (PWC) within a range of 15-50%, wherein the radical-polymerizable unsaturated monomer mixture contains the amido-containing radical-polymerizable unsaturated monomer (M-1) within a range of 0.1-5 mass %, based on the total amount of the radical polymerizable unsaturated monomers. |
