摘要： Coating composition containing a binder/crosslinking agent system, organic solvents, optionally together with pigments and/or extenders and conventional lacquer additives, wherein the binder/crosslinking agent system contains A) 20 to 80 wt. % of carboxy-functional (meth)acrylic copolymers and/or polyesters which are dissolved in the continuous phase of the coating composition, with an acid value of 15 to 300 mg of KOH/g, B) 80 to 20 wt. % of epoxy-functional crosslinking agents, wherein the numerical ratio between the component A) carboxyl groups and the component B) epoxy groups is between 1:1 and 1:3, and the epoxy-functional crosslinking agent B) comprises at least one epoxy-functional crosslinking component B1) which is dissolved in the continuous phase of the coating composition and at least one epoxy-functional component B2) dispersed in the continuous phase of the coating composition, wherein the numerical ratio of the epoxy groups of the crosslinking components B1) and B2) is 10:1 to 1:5 and wherein the organic solvents comprise 0 to 35 wt. % of one or more conventional organic lacquer solvents containing oxygen and 65 to 100 wt. % of one or more conventional lacquer hydrocarbons.
