Title:
WATER-BASED PAINT COMPOSITION SET AND MULTILAYER-COATING-FILM FORMING METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2021/132258
Kind Code:
A1
Abstract:
The present invention provides a water-based paint composition with which it is possible to form a metallic coating film having excellent design properties and to form a coating film exhibiting good coating-film physical properties. Provided is a water-based paint composition set for forming a multilayer coating film, the water-based paint composition set containing a first base paint composition for forming a first base coating film and a second base paint composition for forming a second base coating film. The first base paint composition contains a first coating-film forming resin, a first hardener, a first inorganic brightener, and a first hydrophobic associative viscous agent. The first inorganic brightener is formed of one or more substances selected from the group consisting of silica, talc, calcium carbonate, kaolin, barium sulphate, and diatomaceous earth. The second base paint composition contains a second coating-film forming resin, a second hardener, a second bright material, a second inorganic viscous agent, a second hydrophobic associative viscous agent, and a second dispersing agent. The second inorganic viscous agent contains a layered material having a laminated structure in which many inorganic crystal layers are laminated.
