Abstract

L'invention concerne une couche mince en résine imprimée destinée à la stratification d'une feuille décorative, présentant des motifs de caractéristique de conception égale ou supérieure à celle d'une feuille décorative classique utilisant une couche mince en résine de polychlorure de vinyle, présentant d'excellentes propriétés de surface telles qu'une résistance aux tâches, et une feuille décorative stratifiée avec la couche mince en résine. La couche mince en résine imprimée destinée à la stratification d'une feuille décorative est produite par stratification, dans l'ordre mentionné, d'une couche de résine adhésive (10), une couche de résine de base (4) faisant office de base d'impression et constituée de téréphtalate de polybutylène modifié, une couche d'impression (5) constituée d'une couche (5b) à motif imprimé et d'une couche (5a) imprimée unie, une couche de protection de surface (6) gaufrant sélectivement la couche (5), et une couche (8) de régulation de brillance appliquée sélectivement sur la couche (6). Une feuille décorative (9) est formée par collage de cette couche mince de résine imprimée sur une feuille de base (2) telle qu'une plaque de bois, une feuille de carton et une plaque de métal.
