Protective film composition for label with enhanced printing protection function, label manufacturing method and label using the same

The present invention relates to a protective film composition for a label with enhanced print protection function, a method for manufacturing a label using the same, and a label, and more particularly, to printing of a label by a UV curing method using a UV stock solution in which epoxy acrylate and urethane acrylate are mixed It relates to a protective film composition for a print protection function-enhancing label forming a film on a part, a method for manufacturing a label using the same, and a label.

In general, labels are used to increase surface curability to eliminate peeling, dents, scratches, etc. of printed parts, and to prevent print breakage by improving slip properties of labels. As an example, in the process of preparing the label coating solution, the coating solution is first applied to the surface of the label that has been printed. Then, when the coated part is cured with an ultraviolet lamp while the coating liquid is applied, the applied coating liquid is cured to form a transparent protective film that protects the printed layer, thereby protecting the printed layer from external impacts such as peeling, dents, and scratches. and maintains a certain gloss and slippery property.

However, although the appearance of the coating film produced by the above process is beautiful, it is difficult to display and add a label, and it is difficult to separate the label when removing it. Accordingly, it is necessary to research and develop a label for strengthening printing protection that does not affect the recognition of the printed layer while protecting the printed layer.
