Abstract

The invention aims at the limitation that a thermal transfer ribbon is difficult to apply to the surfaces of substrates such as metal in the prior art, and provides a marking film for the surface of ahard smooth substrate. A method for preparing the marking film comprises the following steps: printing marking information on the surface of a TPU thin film through heat transfer printing via a thermal transfer ribbon, then carrying out heating and pressurizing to enable the TPU thin film to be melted and to be bonded with the surface of metal, and carrying out cooling to obtain the marking film.The thermal transfer ribbon comprises a ribbon base, wherein the two sides of the ribbon base are coated with a back coating and a thermal transfer layer respectively, and the thermal transfer layeris sequentially composed of a protective layer and a bonding layer from inside to outside from the surface of one side of the ribbon base. The marking film can reach the bonding strength required in application, is good in corrosion resistance, and avoids damage caused by chemical etching.

Description

technical field

[0001] The invention belongs to the technical field of thermal transfer materials, and in particular relates to a marking film for the surface of a hard and smooth substrate and a processing technology thereof. Background technique

[0002] In recent years, with the development of thermal transfer printing technology, the use of carbon ribbon thermal transfer to replace traditional printing methods has become more and more widespread. However, the printing on the surface of metal and other materials is limited by the transfer method of carbon ribbons. After the tape is printed on the label, it is pasted, or it is chemically etched. The former has poor bonding strength and resistance to complex conditions such as alcohol, sunlight, and acid-base corrosion, while the latter will cause damage to glass, ceramics, etc., and is not economical.
