Document Type and Number:
WIPO Patent Application WO/2012/086723
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a contamination-resistant coating composition capable of forming a coating film which is excellent at maintaining contamination resistance and corrosion resistance with respect to rainwater etc., and in particular, a contamination-resistant coating composition suitable for forming a topcoat coating film on coated metal sheets with a sheen that is not more than a semi-gloss. A contamination-resistant coating composition is provided as a means of solving such a problem, said contamination-resistant coating composition containing a specific organosilicate and/or a condensate thereof, and a silsesquioxane compound containing an average of two or more reactive groups per molecule, in a resin binder containing a polyester resin component containing a specific hydroxyl group-containing polyester resin, and a cross-linker, which is a melamine resin and/or a polyisocyanate compound. A coating film forming method in which the coating composition is used, and a coated metal plate which has been coated with the coating composition are also provided.
