Abstract
A transfer sheet for applying images to glass, plexiglass and the like to simulate the look of an etched surface is prepared by a three-step screen printing process wherein a polystyrene or release coated paper base is first coated with nitrocellulose and then heated. Thereafter a further coat comprising a combination of nitrocellulose, a silica flattening agent and mica/silica is applied followed by further heating. A screen printable solvent based adhesive suitable for polystyrene or paper is then applied, then heated and, thereafter a slip sheet applied to the adhesive side to permit stacking.
