Patent

CA 2204628

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.

L'invention concerne des articles d'impression ayant une couche de poudre de toner sèche qui a été fusionnée en utilisant un adhésif autocollant et une faible compression. Des adhésifs autocollants appropriés sont des copolymères ou des polymères d'alkyle acrylate, des copolymères ou des polymères d'éther d'alkyle vinylique, les copolymères de butadiène-styrène, polyisobutylène, polybutadiène. De tels articles d'impression comprennent en outre une couche de recouvrement transparente disposée sur la surface portant la poudre toner sèche fusionnée. L'invention décrit également des procédés de formation d'articles d'impression, un procédé comprenant les étapes d'application de la poudre de toner sèche sur la surface d'un premier substrat, d'application d'une composition comprenant un adhésif autocollant sur la surface d'un second substrat, et le laminage des deux substrats pour mélanger la poudre de toner sèche et l'adhésif autocollant. Soit le premier soit le second substrat peut être la couche de recouvrement transparente de l'article d'impression obtenu.
