ABSTRACT:
Disclosed is an improved plastisol composition comprising a finely-divided vinyl chloride polymer, filler, a primary plasticizer, and a polyaminoamide-polyimidazoline adhesion promoter. The improvement for overcoating said plastisol with an acid catalyzed topcoat comprises a plasticizer/promoter phase which comprises said primary plasticizer, said adhesion promoter, and an effective amount of a secondary plasticizer non-ionic solvent effective in solvating the adhesion promoter in the plasticizer/promoter phase. The plasticizer/promoter phase is pre-formed for addition with the remaining ingredient for the plastisol composition.
