Abstract
Abstract A quaternary ammonium group-containing material which is obtained from reacting a polyepoxide with an amine containing at least one acyclic group of about 8 to 30 carbon atoms and optionally an amine containing an alkyl- arylpoly ether moiety is disclosed. The resins are useful as pigment grinding vehicles and in the formulation of pigment paste, particularly pigment paste with high pigment loadings. When formulated into cationic electrodepositable compositions, the pigment grinding vehicles provide for cured electrodeposited coatings of excellent corrosion resistance, particularly over untreated and oily steel.

A quaternary ammonium group-containing material which is obtained from reacting: (i) a polyepoxide having a 1,2-epoxy equivalency greater than one, and (ii) an amine containing at least one organic group which contains an acyclic moiety of about 8 to 30 carbon atoms, under conditions sufficient to form the quaternary ammonium group.
Claim 2
Dependent Claim
51 words
A quaternary ammonium group-containing material which is obtained from reacting: (i) a polyepoxide having a 1,2-epoxy equivalency greater than one, and (ii) an amine containing at least one organic group which contains an acyclic moiety of about 8 to 30 carbon atoms, under conditions sufficient to form the quaternary ammonium group.
Claim 3
Dependent Claim
95 words
A quaternary ammonium group-containing material which is obtained from reacting: (i) a polyepoxide having a 1,2-epoxy equivalency greater than one, (ii) an amine containing at least one organic group which contains an acyclic moiety of about 8 to 30 carbon atoms, and (iii) an amine containing an alkylarylpolyether moiety of the formula: wherein R is an alkyl group containing from 1 to 30 carbon atoms, R' is hydrogen or lower alkyl containing from 1 to 5 carbon atoms and x is equal to 3 to 20, under conditions sufficient to form the quaternary ammonium group.
Claim 4
Dependent Claim
95 words
