Claims
- 1. 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: ##STR6## wherein R is an alkyl group containing from 1 to 30 carbon atoms, R' is hydrogen or lower aklyl containing from 1 to 5 carbon atoms and x is equal to 3 to 20,
- under conditions sufficient to form the quaternary ammonium group; the equivalent ratio of (i):(ii):(iii) is about 1:0.4 to 1:0.1 to 0.6 and the equivalent ratio of (i):(ii)+(iii) is equal to or greater than 1.
- 2. The quaternary ammonium group-containing material of claim 1, wherein the polyepoxide is a polyglycidyl ether of a polyol.
- 3. The quaternary ammonium group-containing material of claim 2, wherein the polyepoxide is a polyglycidyl ethter of bisphenol A, having an epoxy equivalent of about 100 to 500.
- 4. The quaternary ammonium group-containing material of claim 1, wherein the amine is of the structure: ##STR7## wherein R.sub.1, R.sub.2 and R.sub.3 are alkyl groups of which at least one group contains from about 8 to 30 carbon atoms, and at least one group is methyl.
- 5. The quaternary ammonium group-containing material of claim 4 wherein two groups are methyl and one group contains from 8 to 30 carbon atoms.
- 6. The quaternary ammonium group-containing material of claim 4, wherein the amine is N-octadecyldimethylamine.
- 7. The quaternary ammonium group-containing material of claim 1, wherein the amine containing an alkylarylpolyether moiety is derived from the reaction product of:
- (i) an alkylarylpolyether alcohol,
- (ii) an organic diisocyanate, and
- (iii) a hydroxyl-containing tertiary amine.
- 8. A pigment grinding vehicle comprising the quaternary ammonium group-containing material as recited in claim 1 which is at least partially acid-neutralized.
- 9. A pigment paste comprising:
- (A) the grinding vehicle of claim 8,
- (B) a pigment dispersed in (A).
- 10. A pigment paste of claim 9 wherein the weight ratio of (B) to (A) is at least 10:1.
