Abstract
The present invention discloses signage articles having a layer of fused dry toner powder which is fused by employing a tacky pressure-sensitive adhesive and low compression. Suitable tacky pressure-sensitive adhesives include alkyl acrylate polymers or copolymers, alkyl vinyl ether polymers or copolymers, polyisobutylene, polybutadiene, and butadiene-styrene copolymers. Such signage articles further comprise a transparent cover layer disposed over the fused dry toner powder-bearing surface. Also disclosed are methods of forming signage articles, one method comprising the steps of applying dry toner powder to a first substrate surface, applying a composition including a tacky pressure-sensitive adhesive to a second substrate surface, and laminating the two substrates to admix the dry toner powder and the tacky pressure-sensitive adhesive. Either the first or second substrate may be the transparent cover layer of the resulting signage article.
