Embodiment 1

[0050] Embodiment 1: Preparation of transparent fluorescent material

[0051] Organic dyes and organic light-emitting small molecules containing unsaturated bonds can be synthesized by organic solvent synthesis, such as 7-(diethylamino)-4-methyl-2H-1-benzopyran-2-ketocoumarin 1. By selecting an appropriate solvent (for example, acetone, ethanol, etc.) or chemically changing the solvent affinity of the molecule, the organic molecule can be effectively dissolved in the solvent to form a completely colorless and invisible functional luminescent liquid. Down emits a striking characteristic light.

[0052] The obtained luminescent material can be applied to the field of anti-counterfeiting. It can not only make colorful patterns on the colorless and transparent medium, but also emit different lights from the same material under the excitation of different ultraviolet wavelengths, thus greatly improving the level of anti-counterfeiting. .

Embodiment 2

[0053] Embodiment 2: Preparation of transparent fluorescent gravure printing ink

[0054] Add the transparent fluorescent material prepared in Example 1 to the transparent gravure ink at a ratio of 1:50, and dissolve or fully disperse it to obtain a transparent fluorescent ink. The selected transparent ink itself should have printing properties on the PET surface. applicability.

Embodiment 3

[0055] Embodiment 3: Preparation of fluorescent film for thermal transfer

[0056] The transparent fluorescent gravure printing ink that makes in embodiment 2 is printed on the PET film surface that has coated release layer by the mode of gravure printing, and the last gravure printing unit coats binder, and the final product is as follows: figure 1 As shown, a fluorescent film for thermal transfer printing was obtained, and the printing speed was controlled to be 40-70 m / min.

Abstract

The invention relates to fluorescence film for heat transfer printing on a glass surface or a ceramic surface and a preparation method of the fluorescence film, and provides the fluorescence film for the heat transfer printing on the glass surface or the ceramic surface. The fluorescence film for the heat transfer printing on the glass surface or the ceramic surface comprises base material film (1), a release layer (2) located on the base material film (1), a fluorescence ink layer (3) located on the release layer (2), and an adhesive layer (4) located on the fluorescence ink layer (3). Further provided is the preparation method of the fluorescence film for the heat transfer printing on the glass surface or the ceramic surface.

Description

technical field [0001] The present invention relates to a fluorescent film specially used for thermal transfer printing on the surface of glass or ceramics, in particular to a luminescent film based on organic fluorescent material which can be used for thermal transfer printing. The color fluorescent pattern is transferred to the surface of glass or ceramic products by thermal transfer. Background technique [0002] Today, fluorescent anti-counterfeiting has become one of the anti-counterfeiting methods often used by merchants, but at the same time, its application limitations are still quite large. Specifically: [0003] First of all, the color is single. Most of the common fluorescent anti-counterfeiting labels now only achieve single-color anti-counterfeiting, such as the blue fluorescent code on the surface of Zhonghua cigarettes; secondly, the scope of application is narrow. Due to technical limitations, fluorescent anti-counterfeiting is still used in many printing an...
