SUBLIMATION TRANSFER-PRINTING FOR 3D ROUNDED SURFACE, THERMOPLASTIC FILM

摘要

Disclosed is a thermoplastic film capable of comprising a coating layer which receives and transfers sublimation dispersion dye in order that an image, which is printed by ink manufactured by the sublimation dispersion dye, is implemented on a 3D multi-curved surface. The present invention comprises a thermoplastic substrate, a preprocessing adhesion and barrier layer, an absorption layer, and a dye collection layer. The preprocessing adhesion and barrier layer helps the interfacial adhesion between absorption layers which absorb liquids included in ink and forms a film in order that the sublimation dispersion dye is not transferred to the substrate. The absorption layer absorbs the liquids of the ink and settles the image down. The dye collection layer positions the sublimation dispersion dye in a top position of a coating surface.
