Transfer Film

Abstract

The technical problem to be solved by this invention is to eliminate the release layer from the transfer film. The object of this invention is to provide a transfer film that can be applied stably to the transfer process without any trouble. The transfer film of this invention comprises a substrate to be peeled off during the transfer process and a transferred layer to be transferred to an article to be decorated, both of which are laminated directly to each other in a peelable manner by an extrusion laminating process without requiring any release layer.

1 . A transfer film comprising a substrate layer ( 2 ) to be peeled off during transfer process and a transferred layer ( 9 ) to be transferred to an article to be decorated, wherein both layers are directly laminated to each other in a peelable manner by an extrusion laminating process without requiring any release layer. 
   
   
       2 . The transfer film according to  claim 1  wherein said transferred layer ( 9 ) has a protective layer ( 3 ), a printed or vapor-deposited decorative layer ( 11 ), and an adhering layer ( 7 ), which are laminated in this order, wherein at least either one of said substrate ( 2 ) and protective layer ( 3 ) is a synthetic resin film, and wherein the substrate layer ( 2 ) and the protective layer ( 3 ) are directly laminated to each other in a peelable manner by the extrusion laminating process without requiring any release layer. 
   
   
       3 . The transfer film according to  claim 2 , wherein the protective layer ( 3 ) is a protective film ( 3   a ) of a synthetic resin, which is directly laminated with the substrate layer ( 2 ) in a peelable manner by the extrusion laminating process. 
   
   
       4 . The transfer film according to  claim 2  wherein the substrate layer ( 2 ) is a base film ( 2   a ) of a synthetic resin, wherein the protective layer ( 3 ) is a hard coat layer ( 3   b ) of a UV- or heat-cured resin, and wherein said base film ( 2   a ) is laminated directly with said hard coat layer ( 3   b ) in a peelable manner by the extrusion laminating process. 
   
   
       5 . The transfer film according to  claim 2 , wherein a decorative film ( 4 ) of a synthetic resin is laminated between the protective layer ( 3 ) and the adhering layer ( 7 ) and wherein a printed or vapor-deposited decorative layer ( 11 ) is formed at least on either surface of the decorative film ( 4 ). 
   
   
       6 . The transfer film according to  claim 2 , wherein the adhering layer ( 7 ) comprises an adhering film ( 5 ) of a synthetic resin which can be directly adhered by heat seal to the wall of the article to be decorated. 
   
   
       7 . The transfer film according to  claim 5 , which comprises the base film ( 2   a ) made of a polyethylene terephthalate resin, the protective film ( 3   a ) made of a low-density polyethylene resin, and the decorative film ( 4 ) made of a nylon resin.
