Abstract
Abstract A surface-treating paint for shaped plastic articles, said paint being the reaction product of (1) 50 to 95 mole % of an epoxyalkylalkoxysilane of the general formula ##STR1## wherein R 1 represents a divalent hydrocarbon group having 1 to 4 carbon atoms, R 2 and R 3 represent a monovalent hydrocarbon group having 1 to 4 carbon atoms, Q represents a glycidoxy or epoxycyclohexyl group, and m is 0 or 1, and (2) 50 to 5 mole % of a fluorinated alcohol of the general formula H--CF.sub.2 CF.sub.2).sub.p CH.sub.2 OH (II) wherein p is an integer of 1 to 7. The paint may further contain 50 to 5% by weight of the reaction product of (a) 80 to 30 mole % of an epoxyalkylalkoxysilane of general formula (I) with (b) 20 to 70 mole % of an aminoalkylalkoxysilane of the general formula ##STR2## wherein R 1 , R 2 and R 3 are as defined with regard to general formula (I), Z represents a hydrogen atom or an aminoalkyl group, and n is 0 or 1, or a partially hydrolyzed product of the reaction product.
