A thermal transfer label with cracking effect and its production process

Abstract

The invention relates to a heat transfer printing trademark with a cracking effect and a production process thereof. The heat transfer printing trademark with the cracking effect includes a PET film,a release layer, a surface protection layer, a cracking resin layer, a white glue layer, a sublimation prevention layer and a hot melt glue layer which are successively arranged from bottom to top, and the cracking resin layer comprises the following raw materials of a cracking resin, a dry high wear-resisting resin, acetic ether, organic color paste, a color showing agent, a polyether defoaming agent and an organic silicon leveling agent. According to the heat transfer printing trademark with the cracking effect and the production process thereof, the cracking resin layer is mainly composed of the cracking resin and the dry high wear-resisting resin, when the cracking resin layer is heated to a certain degree, macromolecule chains in the cracking resin composition breaks, a cracking pattern is formed, and thus the heat transfer printing trademark has the cracking effect; and by adjusting the ratio between the cracking resin and the dry high wear-resisting resin, the cracking pattern formed by the cracking resin layer is fine and smooth, the effect is obvious, and the bonding fastness between upper and lower layers is good.

Description

technical field [0001] The invention belongs to the field of thermal transfer label preparation, and in particular relates to a thermal transfer label with a cracking effect and a production process thereof. Background technique [0002] Thermal transfer printing is a surface printing method. First, the transfer film is printed, that is, the pattern or text is first printed on the surface of the film, and then the graphics and text on the printing film are transferred to the substrate by heating and pressing through the thermal transfer processing equipment. The surface of the object makes the product bright and beautiful, greatly improves the product grade, increases the added value of the product and the market competitiveness. It is characterized by simple process, few procedures, high efficiency, no pollution, small footprint and low investment. Because its printing process is simple, easy to operate, the required materials are economical and easy to get, and it can be ...
