Abstract
Acrylic plastisol composition comprising a plasticiser component, a plasticiser compatible acrylic polymer powder component of primary particle size ≧0.4 &mgr;m and preferably not more than 30 &mgr;m, and Tg ≧65° C., and a plasticiser incompatible polymer powder component, where both polymers are preformed, are present in the weight ratio 95:5 to 40:60, and in combination are compatibly formulated with the plasticiser component.
