Abstract: Disclosed in this specification is a decal assembly comprising a decal support, a releasable covercoat, a heat activatable layer, and an ink layer. The ink layer forms a digital image. The heat activatable layer has a high adhesion to a ceramic substrate at high temperatures and a low adhesion to the substrate at lower temperatures. Thus the adhesive properties of the decal are activated by heat. The resulting image has excellent adhesion to the substrate and resists the effects of washing.
