Background

The pop (point Of purchasase) billboard, as a shop promotion tool in commercial sale, is Of a type which is not limited by its color, and can effectively attract customers' viewpoints to arouse the desire to buy, and thus is widely used as a low-cost and efficient advertising means.

The conventional thermal transfer printing film generally comprises a carrier film, an image-text decorative layer and an adhesive layer, wherein the image-text decorative layer is separated from the carrier film and transferred to the surface of a printing stock under the action of heat and pressure during transfer by using the adhesive force of the adhesive layer. Hot melt adhesive is widely accepted and applied as an adhesive for thermal transfer printing films after decades of practice, because the hot melt adhesive is a solid substance in a normal state and has good viscosity under the action of heat, and on the other hand, the solvent-type hot melt adhesive can be used as ink to obtain a thin and uniform coating by a printing and coating method, and the coating can obtain high-efficiency and quick bonding effect by a thermal transfer method, such as hot stamping of electrochemical aluminum foil, and thermal transfer of ink pictures and texts on the surfaces of inorganic products and organic products of various shapes. In the curing process of the hot melt adhesive, a large amount of organic solvent needs to be volatilized, so that the environment is easily polluted, and the environment is not protected.

The ultraviolet curing adhesive is generally accepted due to the irreversibility after curing, the firmness of the adhered pattern, the acid and alkali resistance and the wide applicability to the adhered objects, and in addition, the ultraviolet curing adhesive does not contain organic solvent, so the environment is not polluted in the using process, and the ultraviolet curing adhesive is particularly suitable for the requirement of environmental protection.
