Abstract

Abstract Translated from German Unter dem Einfluss eines kationischen Katalysators in höhermolekulare Stoffe überführbare Substanzen (a), wie 1.2-Epoxide, Aminoplaste, Vinylmonomere oder -präpolymere oder Phenoplaste, werden so überführt durch Belichtung mit aktinischer Strahlung in Gegenwart eines Carbamoylsulfoxoniumsalzes (b) der Formel worin p, q, Ar, R 6 , R 7 , R 8 , R 9 , R 10 , r, t und Z'- die im Anspruch 1 angegebene Bedeutung haben, zum Beispiel in Gegenwart von Acetanilinodimethylsutfoxonium-hexafluorophosphat, Benzoylcarbamoyldimethylsulfoxonium-hexafluorophosphat, 3.4-Dichloracetanlinodimethylsulfoxonium hexafluoroarsenat, 2,4-Bis-(dimethylsulfoxoniummethyl- carbamoyl)-toluol-dihexafluorophosphat. 4-Methylacetanilinodimethylsulfoxonium-chlorid und Tris-(acetanilinodimethylsulfoxonium)-orthophosphat. Ist (a) ein Polyepoxid-oder Resolharz. so lässt es sich mittels (b) photopolymerisieren und anschliessend durch Erhitzen mit einem latenten Heisshärtungsmittel vernetzen.- Substances (a) which can be converted into higher molecular weight substances under the influence of a cationic catalyst, such as 1,2-epoxides, aminoplasts, vinyl monomers or prepolymers or phenoplasts, are thus converted by exposure to actinic radiation in the presence of a carbamoylsulfoxonium salt (b) of the formula wherein p, q, Ar, R 6 , R 7 , R 8 , R 9 , R 10 , r, t and Z'- have the meaning given in claim 1, for example in the presence of acetanilinodimethylsutfoxonium hexafluorophosphate, benzoylcarbamoyldimethylsulfoxonium hexafluorophosphate, 3,4-dichloroacetanlinodimethylsulfoxonium hexafluoroarsenate, 2,4-bis (dimethylsulfoxoniummethylcarbamoyl) toluene dihexafluorophosphate. 4-methylacetanilinodimethylsulfoxonium chloride and tris (acetanilinodimethylsulfoxonium) orthophosphate. Is (a) a polyepoxide or resol resin. it can be photopolymerized using (b) and then crosslinked by heating with a latent heat curing agent.
