Document Type and Number:
WIPO Patent Application WO/2011/162359
Kind Code:
A1
Abstract:
Disclosed is a stain-proof coating composition which does not contain copper or any copper compound (e.g., cuprous oxide) and therefore enables the production of a stain-proof coating film that does not undergo discoloration or cracking caused by ultraviolet ray or moisture, can have a low VOC and long-term anti-stain properties at high levels simultaneously, and has excellent mechanical strength. Specifically disclosed is a two-part hydrolysable stain-proof coating composition which comprises two liquids, i.e., a first component comprising a polyester resin and a paste-like second component containing zinc oxide, wherein the solid content in the polyester resin has an acid value and a hydroxy value of 50-200 mgKOH/g and 100 mgKOH/g, respectively, the polyester resin has a viscosity of 500 mPa·s or less at 25˚C, and wherein the coating composition is characterized in that the content of a volatile organic compound is 400 g/L or less relative to the total amount of the first and second components, and copper or any copper compound is not contained.
