Patent ID: 7361702

Claim:
A coating material composition, comprising: (A) one or more of (i) at least one compound of the formula (I) in which R 1 is a radical with at least one carbon atom, and the free radical R 1 • corresponding to R 1 is able to initiate a free-radical polymerization of unsaturated monomers, the radicals R 2 , R 3 , R 4 , R 5 , R 6 , and R 7 are identical or different straight or branched-chain, substituted or unsubstituted alkyl groups, substituted or unsubstituted aralkyl, alkylaryl or aryl groups, and —CR 2 R 3 or —CR 6 R 7 may be part of a cyclic structure, the radicals R 4 and R 5 are cyano-, ether-, hydroxyl-, nitro- or carbonyl-containing groups or R 4 CNCR 5 is part of a substituted or unsubstituted cyclic structure to which at least one further saturated or unsaturated ring may be fused, or —CR 2 R 3 R 4 or —CR 5 R 6 R 7 is part of an aromatic ring; and (ii) at least one compound of the formula (Ia) in which R 1 is a radical with at least one carbon atom, and the free radical R 1 • corresponding to R 1 is able to initiate a free-radical polymerization of unsaturated monomers, R 8 and R 9 are hydrogen, identical or different straight- or branched chain, substituted or unsubstituted alkyl groups, substituted or unsubstituted aralkyl, alkylaryl or aryl groups, which may possess a polymeric character, at least two of the radicals R 9 are a phenyl radical or a substituted phenyl radical; and (B) p-toluenesulfonic acid, one or more ethylenically unsaturated monomers, and at least one additive selected from the group consisting of a polymer, a crosslinker, a crosslinking catalyst, a pigment, a dye, a filler, a reinforcing filler, a rheological aid, a wetting agent, a defoamer, an adhesion promoter, an additive for improving the surface smoothness, a flatting agent, a leveling agent, a film formation auxiliary, a dryer, an antiskinning agent, a light stabilizer, a corrosion inhibitor, a biocide, a flame retardant, a polymerization inhibitor, a photoinhibitor and a plasticizer; and wherein the composition comprises the compound of formula I(a) which comprises diphenyl ethane units.
