Abstract
Ungelled amidation reaction products of a polycarboxyl-containing material and a polyamine having at least one ether group are produced. The ungelled products can be mixed with a crosslinking resin to provide a coating composition having good durability and stain-resistance.
Claims31
An ungelled amidation product containing primary amine groups, secondary amine groups or a mixture thereof and carboxyl groups obtained by the reaction of (1) a polyamine containing aliphatic amine groups and having at least one ether group with (2) a polycarboxyl-containing material selected from the group consisting of an acrylic resin, polyester resin, polyamide resin, or mixture thereof and wherein the carboxyl content of the polycarboxyl-containing material ranges from about 0.5 milliequivalents to about 12 milliequivalents of carboxyl per gram.
A coating composition consisting essentially of:
- (a) from about 5 percent to about 95 percent of an ungelled amidation product containing primary amine groups, secondary amine groups or a mixture thereof and carboxyl groups obtained by the reaction of (1) a polyamine containing aliphatic amine groups and having at least one ether group with (2) a polycarboxyl-containing material selected from the group consisting of an acrylic resin, polyester resin, polyamide resin, or a mixture thereof and wherein the polycarboxyl-containing material has a carboxyl content ranging from about 0.5 milliequivalents to about 12 milliequivalents of carboxyl per gram;
- and
- (b) from about 5 percent to about 95 percent of a crosslinking resin.
