Color and/or effect coating system comprising a combination effect coat

A coating system, comprising a combination effect coat which simultaneously provides:

• (i) at least one function selected from the group consisting of color, effect or the combination thereof;
• as well as
• (ii) at least one function selected from the group consisting of corrosion protection, adhesion promotion, absorption of mechanical energy, or the combination of two or more of the foregoing;
• said combination effect coat resulting from the application and curing of a pigmented powder slurry having a residual volatile solvent content of less than 1% by weight, wherein the pigmented powder slurry is curable thermally, or thermally and with actinic radiation;
• wherein the pigmented powder slurry consists of finely divided dimensionally stable constituents having an average particle size of from 0.8 to 40 μm, and
• wherein the pigmented powder slurry comprises:
• a (meth)acrylate copolymer having an epoxide equivalent weight of 400 to 2500;
• and
• a color pigment, an effect pigment, or a combination thereof.
