The transfer film used in thermal transfer printing is mainly composed of film, transparent coating layer and printing ink on the surface, and some problems are often encountered in the transfer printing, such as the scratch resistance and wear resistance of the protective layer coating on the surface of the printed pattern is not good enough , The adhesion between the paint layer and the printing ink is poor, and the paint peels off, which affects the aesthetics of the transfer.

Utility model content

The technical problem to be solved by the utility model is: in order to solve the poor scratch resistance and wear resistance of the protective coating layer on the surface of the printing ink layer in the existing transfer film, the printing ink layer cannot be well protected, and at the same time the surface of the printing ink layer The adhesion between the protective coating layer and the printing ink layer is poor, and the peeling phenomenon of the protective coating layer is prone to occur. The light transmittance of the protective coating layer on the surface of the printing ink layer in the existing transfer film is poor, which easily causes the color distortion of the printing ink layer. To solve the problem of high defective rate, the utility model provides a transfer film for thermal transfer printing, which has high scratch resistance and wear resistance by coating a UV curable coating layer between the film layer and the printing ink layer , and has a large adhesion between the printing ink layer, which completely solves the phenomenon that the protective coating layer is easy to peel off. At the same time, the UV curing coating layer has high light transmittance, which avoids the color distortion of the printing ink layer and improves the conversion The qualification rate of printing film.

The technical scheme that the utility model solves its technical problem adopts is:

A transfer film for thermal transfer, comprising a thin film layer, on which a transparent UV curable paint layer, a printing ink layer and a colored primer layer are sequentially coated.

Preferably, a layer of hot-melt glue is also provided on the colored primer layer.

Specifically, the film layer is a PET film, a PE film, a PP film or a PVC film.

Specifically, the printing ink layer is a UV curable printing ink layer or a heat curing printing ink layer.

Specifically, the colored primer layer is a UV-cured colored primer layer or a heat-cured colored primer layer.

The beneficial effects of the utility model are: the utility model provides a transfer film for thermal transfer printing, by coating a layer of UV curable coating layer between the film layer and the printing ink layer, it has high scratch resistance and wear resistance performance, and has a large adhesion with the printing ink layer, which completely solves the phenomenon that the protective coating layer is easy to peel off. At the same time, the UV curing coating layer has a high light transmittance, which avoids the color distortion of the printing ink layer and improves the The qualification rate of the transfer film; the transfer film of the present invention uses at least one layer of UV curable coating, which has the advantages of low energy consumption and fast curing speed, which greatly saves production costs and shortens the production cycle.
