Abstract:
1. A paint composition, comprising: a hydroxyl group containing resin (A), comprising structural units based on 2,2-dimethylolalkanoic acid, a hydroxyl group value of from 200 to 400 mgKOH/g, and less than 25 weight % in the resin solid fraction of structural units based on a lactone compound; a hydroxyl group containing resin (B), comprising a hydroxyl group value from 50 to 200 mgKOH/g, and from 25 to 75 weight % in the resin solid fraction of structural units based on a lactone compound; and a crosslinking agent (C) comprising at least two OH-reactive functional groups per molecule, wherein the crosslinking agent (C) is a combination of an isocyanate compound and melamine resin having a solid fraction mass ratio of from 100/0 to 75/25 wherein the resin solid fraction weight ratio (A)/(B) of the hydroxyl group containing resin (A) and the hydroxyl group containing resin (B) is from 90/10 to 10/90.
