Patent

CA 2516026

The disclosed invention relates to a method of making a dry paint transfer laminate 100, comprising: extruding a paint film layer 110 over a release liner 130; and extruding a pressure sensitive adhesive layer 120 over the paint film layer 110, wherein the release liner 130 comprises: a backing liner 132 having an upper surface 133 and a lower surface 134; a first release coating layer 135 overlying the upper surface 134 of the backing liner 132; the first release coating layer 135 comprising a resinous material hardened or cured to bond to the backing liner 132 and form a matte release surface spaced from the backing liner 132, the matte release surface contacting the extruded paint film layer 110; the matte release surface of the release liner 130 releasably adhered to the paint film layer 110 for transferring a matte finish to the paint film layer 110 when the release liner 130 is removed therefrom.

L'invention concerne un procédé servant à fabriquer un stratifié à transfert de peinture sèche (100). Ledit procédé consiste à extruder une couche mince de peinture (110) sur une doublure anti-adhésive (130) et à extruder une couche adhésive autocollante (120) sur la couche mince de peinture (110). La doublure anti-adhésive (130) comprend : une doublure de support (132) pourvue d'une surface supérieure (133) et d'une surface inférieure (134) ; une première couche de revêtement anti-adhésif (135) disposée par-dessus la surface supérieure (134) de la doublure de support (132) ; la première couche de revêtement anti-adhésif (135) comprenant un matériau résineux durci ou traité pour se fixer sur la doublure de support (132) et former ainsi une surface anti-adhésive mate espacée de la doublure de support (132), ladite surface anti-adhésive mate venant en contact avec la couche mince de peinture (110) extrudée ; la surface anti-adhésive mate de la doublure anti-adhésive (130) adhérant de manière libre à la couche mince de peinture (110), de sorte à transférer une finition mate à la couche mince de peinture (110) lorsque la doublure anti-adhésive (130) est retirée de ladite couche.
