Title
(EN) SHEETING HAVING AN OPTICAL CORE LAMINATED TO A VINYL FILM, RETROREFLECTIVE ARTICLES, AND METHODS
(FR) REVETEMENT FEUILLE A COEUR OPTIQUE LAMINE JUSQU'A UN FILM DE VINYLE, ARTICLES RETROREFLECHISSANTS, ET PROCEDES
Abstract
(EN)
Sheeting, such as retroreflective sheeting, methods of making such sheeting, and articles containing such sheeting. A sheeting includes: a vinyl film having two major surfaces; a preformed optical core laminated to a first major surface of the vinyl film; a primer disposed between the vinyl film and the preformed optical core, wherein the primer includes a urethane polymer; and optionally, graphics positioned between the primer and the optical core or the primer and the vinyl film.
(FR)
L'invention concerne un revêtement feuille, du type rétroréfléchissant, et des procédés relatifs à sa fabrication, ainsi que des produits dotés de ce revêtement. Le revêtement comprend un film de vinyle présentant deux surfaces majeures; un coeur optique préformé laminé jusqu'à une première surface majeure du film de vinyle; une couche d'apprêt entre le film de vinyle et le coeur préformé, à base de polymère d'uréthanne; et éventuellement des éléments graphiques entre l'apprêt et le coeur optique ou entre l'apprêt et le film de vinyle.
