Abstract
Abstract A novel quaternary ammonium group-containing material which is obtained from reacting a monoepoxide with an amine containing at feast one organic group containing an acyclic moiety of from about 8 to 30 carbon atoms is disclosed. The quaternary ammonium group-containing materials are useful as pigment grinding vehicles and in the formulation of pigment paste, particularly pigment paste with high pigment loadings. When formulated in cationic electrodepositable compositions, the pigment grinding vehicles provide for cured electrodeposited coatings of ex- cellentcorrosion resistance, particularly over untreated and oily steel.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
45 words
A quaternary ammonium group-containing material which is obtained from reacting: (1) a monoepoxide, and (2) an amine containing at least one organic group which contains an acyclic moiety of from about 8 to 30 carbon atoms, under conditions sufficient to form the quaternary ammonium group.
Claim 2
Dependent Claim
45 words
A quaternary ammonium group-containing material which is obtained from reacting: (1) a monoepoxide, and (2) an amine containing at least one organic group which contains an acyclic moiety of from about 8 to 30 carbon atoms, under conditions sufficient to form the quaternary ammonium group.
Claim 3
Dependent Claim
27 words
The quaternary ammonium group-containing material-of Claim 1, wherein (1) is a glycidyl ether or ester containing an acyclic group of from about 4 to 24 carbon atoms.
Claim 4
Dependent Claim
20 words
The quaternary ammonium group-containing material of Claim 2, wherein the fatty glycidyl ester is a glycidyl ester of versatic acid.
Claim 5
Dependent Claim
52 words
The quaternary ammonium group-containing material of Claim 1, wherein the amine is of the structure: wherein R 1 , R 2 and R 3 are alkyl groups of which at least one group contains an acyclic moiety of from about 8 to 30 carbon atoms and at least one group is methyl.
Claim 6
Dependent Claim
20 words
The quaternary ammonium group-containing material of Claim 1, containing at least two alkyl groups of 1 to 4 carbon atoms.
