Abstract

Ethylene-vinyl acetate copolymers having a melt index of 2,000 to 7,500 and containing from 10 to 22% vinyl acetate are useful in hot melt road marking compositions containing from 1 to 30% of the EVA copolymer; from 0 to 29% by weight of a binder resin; and from 0 to 5% by weight of a plasticizer, the balance of the composition typically comprising from 70 to 80% by weight of aggregates, made up of particulate materials such as sand and/or fillers and/or pigments such as calcium carbonate and titanium dioxide.
