Adhesion promoters of plastisols, capable of maintaining plastisol color stable towards the effect of the application thermal treatment

摘要: The object of the invention are adhesion promoters for plastisols polyvinylchloride polymers or copolymers, characterized in that they constituted by polyaminoamidic resins obtained means condensation of: 1 equivalent carboxylic acids, polymerization unsaturated fatty composition comprised within following ranges: 0-2% monomers, 10-50% dimers, 50-90% trimers, with from 1.0 to 2.2 equivalents an heterocyclic amine general formula ##STR1## wherein R can be H alkylamino group --R'--NH 2 , R' is a saturated alifatic chain.
