Abstract
Graphic arts media are provided which offer raised, three-dimensional effects. A basic medium is formulated of a colorant, film-forming binder, a solvent vehicle and thermally expandable microspheres. The microspheres are treated to preclude or inhibit solvation in the solvent vehicle by coating with a compound which is a non-solvent for the microspheres but which preferentially wets the surface thereof. Alkyl alcohols having about 3 to 5 carbon atoms in the alkyl chain are employed. The medium is selectively applied to a substrate, dried, and heated to expand the microspheres.
