Abstract
Abstract What is disclosed is an adhesion improved plastisol composition adaptable to use as a coating material or adhesive and comprising a finely-divided vinyl chloride polymer together with a plasticizer and filler and an adhesion improver which is (1) a condensation product formed between a polymerized fatty acid mixture having a content, X, measured in weight percent of said mixture, of tripolymeric and higher polymeric fatty acids and excess polyalkylene polyamine; (2) a product formed by reacting said condensation product (1) with an aldehyde or ketone; or (3) an adduct formed between said condensation product (1) and an epoxy compound; said adhesion improver (1), (2), or (3) having a content, Y, of imidazoline groups, expressed as a percent by weight of condensation product (1), such that the values of both X and Y are at least 40, or if the value of either X or Y is below 40 then the other value is at least 40+Z, where Z is the difference between 40 and the smaller value.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
182 words
An adhesion improved plastisol composition adaptable to use as a coating material or adhesive and comprising a finely-divided vinyl chloride polymer together with a plasticizer and filler and from 0.5 to 5 percent, by weight of said plastisol composition, of an adhesion improver which is (1) a condensation product formed between (a) a polymerized fatty acid mixture having a content, X, measured in weight percent of said mixture, of tripolymeric and higher polymeric fatty acids, and (b) excess polyalkylene polyamine; (2) a product formed by reacting said condensation product (1) with an aldehyde or ketone; or (3) an adduct formed between said condensation product (1) and a deficiency of an epoxy compound; said adhesion improver (1), (2), or (3) having a content, Y, of imidazoline groups, expressed as a percent by weight of condensation product (1), such that the values of both X and Y are at least 40, or if the value of either X or Y is below 40 then the other value is at least 40 + Z, where Z is the difference between 40 and the smaller value.
Claim 2
Dependent Claim
182 words
An adhesion improved plastisol composition adaptable to use as a coating material or adhesive and comprising a finely-divided vinyl chloride polymer together with a plasticizer and filler and from 0.5 to 5 percent, by weight of said plastisol composition, of an adhesion improver which is (1) a condensation product formed between (a) a polymerized fatty acid mixture having a content, X, measured in weight percent of said mixture, of tripolymeric and higher polymeric fatty acids, and (b) excess polyalkylene polyamine; (2) a product formed by reacting said condensation product (1) with an aldehyde or ketone; or (3) an adduct formed between said condensation product (1) and a deficiency of an epoxy compound; said adhesion improver (1), (2), or (3) having a content, Y, of imidazoline groups, expressed as a percent by weight of condensation product (1), such that the values of both X and Y are at least 40, or if the value of either X or Y is below 40 then the other value is at least 40 + Z, where Z is the difference between 40 and the smaller value.
Claim 3
Dependent Claim
15 words
A plastisol as in claim 1 wherein said adhesion improver is a condensation product (1).
Claim 4
Dependent Claim
15 words
A plastisol as in claim 1 wherein said adhesion improver is a reaction product (2).
Claim 5
Dependent Claim
14 words
A plastisol as in claim 1 wherein said adhesion improver is an adduct (3).
Claim 6
Dependent Claim
56 words
The method of forming a coating or adhesive bond of a vinyl chloride polymer on a substrate which comprises applying an improved plastisol as in claim 1 to said substrate and then baking said substrate having said plastisol thereon at a temperature of at least about 90° C., said substrate not melting at the baking temperature.
