Epoxy compounds for use as components of aqueous coating compositions

Abstract

A compound of Formula (1): ##STR1## wherein: X is E--(L.sup.4 O).sub.m --CO--(T).sub.p ; Y is --Si(R.sup.1).sub.3 or X as defined above; T is O, CH.sub.2 or NR.sup.2 ; P is 0 or 1; q is 0, 1, 2, 3 or 4; E comprises an alicyclic or aliphatic epoxy group; each L.sup.1, L.sup.2, L.sup.3 and L.sup.4 independently is an unsubstituted or substituted alkylene group of 1 to 6 carbon atoms wherein any substitution is selected from methyl, amino, ester, hydroxy and ester groups; m is 0 or 1; each R.sup.1 when Y is --Si(R.sup.1).sub.3 is independently unsubstituted alkyl or substituted alkoxy provided that at least one R.sup.1 is unsubstituted alkoxy; and each R.sup.2 independently is H, --L.sup.1 X unsubstituted or substituted alkyl wherein any substitution is selected from poly(oxyalkylene), epoxy and hydrolyzable silyl groups, or --CONH(C.sub.1-20 -alkyl). The compounds are useful in coating compositions and films and coatings formed therefrom.
