Abstract
This invention relates to compositions for forming opaque, abrasion-removable masks on substrates. The compositions, which include a texture modifying amount of solid or hollow microspheres, have enabled depression or embossing of the surface of the printed substrates to be obscured so that they cannot be seen by the naked eye. The compositions can be based on plastisols, pigmented polymer solution, or pigmented aqueous emulsions. The invention further provides substrates, for example lottery tickets, having abrasion-removable masks formed from compositions of the invention.
