Polyvinyl chloride-plastisol having improved adhesion
First Claim
1. A method which comprises applying to a substrate material a plastisol composition comprising a polymer of vinyl chloride and then baking the composition onto the substrate material at a temperature between about 100°
- C. and 200°
C., said plastisol composition further comprising from 0.05 to 5 percent, by weight of said plastisol composition, of an adhesion improver which is a compound or compounds having an azomethine group and a silane group and wherein, if said azomethine group and said silane group are separately present in different compounds, then said compound having a silane group is an aminosilane.
