Claim 1
Independent Claim
118 words
A non-toxic method for coating a substrate which comprises: (1) treating the surface of the substrate with a solventless photocurable mixture comprising by weight (A) A non-toxic oxirane containing silicone or organic resin (B) An effective amount of a non-toxic arylonium salt (2) Irradiating the treated substrate of (1) with actinic or visible light, until a tack-free surface is obtained on the substrate, where the arylonium salt is selected from the class consisting of hexafluorophosphates, hexafluoroarsenates and hexafluoroantimonates and at least one of the aryl radicals of the arylonium hexafluorometalloid salt has a nuclear bound -OR group attached to the aryl nucleus by a carbon-oxygen linkage, where R is an alkyl radical having at least 8 carbon atoms.
