Patent ID: 7109262

Claim:
An aqueous effect coating material comprising (A) at least one water-soluble, -dilutable and/or -dispersible binder, (B) at least one effect pigment selected from the group consisting of optical effect pigments, electrically conductive pigments, magnetically shielding pigments, fluorescent pigments, and combinations thereof, and (C) at least one silicon compound of the general formula [(E) n L]Si(R 1 )(R 2 )(R 3 ) (I) wherein n is an integer from 1 to 5; E is a reactive functional group; L is an at least divalent, linking, organic group; R 1 is a substituted radical or an unsubstituted radical, and wherein the radical is at least one of a cycloalkoxy radical, an alkoxy radical, an aryloxy radical, a cycloalkyl radical an alkyl radical, and/or an aryl radical; and R 2 and R 3 independently of one another are a hydroxyl group, a substituted radical, or an unsubstituted radical, and wherein the radical is at least one of a cycloalkoxy radical, an alkoxy radical, and/or an aryloxy radical, wherein the at least one silicon compound (C) stabilizes the at least one effect pigment (B).
