Embodiment Construction

[0021] A colorful thermal transfer pearlescent film, which sequentially comprises: a base layer, a release agent layer, a pearlescent layer, a black ink layer, a six-color ink layer for printing, a white ink layer, and a hot-melt adhesive layer.

[0022] The printing thickness of the pearlescent layer is 50±10 μm, and the printing temperature is 80°C. The raw material of the pearlescent layer is a mixture of pearlescent ink and binder, and the ratio of pearlescent ink and binder is 1:5. The pearlescent ink is prepared by mixing toluene and butanone in a ratio of 1:1 as a solvent, and the pearlescent powder accounts for 20% of the total mass of the ink. The pearl powder is selected from glass powder or mica powder, and the binder is polyurethane resin.

[0023] The preparation method of the raw material of the pearlescent layer is as follows: first, the pearlescent powder is soaked in the solvent in proportion for 0.5-1 hour and stirred to obtain the pearlescent ink; then, the ...

Abstract

The invention discloses a colorful thermal transfer pearlescent film and a preparation method thereof. The pearlescent film sequentially comprises: a base layer, a release agent layer, a pearlescent layer, a black ink layer, a six-color ink layer for printing, a white ink layer, Hot melt adhesive layer. In the colorful thermal transfer pearlescent film of the present invention, the black ink layer is matched with the pearlescent layer, and the pearlescent powder particles are wrapped to form a grainy effect, which can produce a two-color change effect, and the printed picture has a grainy feel, which increases the luster and The brightness is more exquisite than the previous pattern, the visual effect is better, the focus is more prominent, the preparation process is simple, and it is worth promoting.

Description

technical field [0001] The invention belongs to the field of thermal transfer printing, in particular to a colorful thermal transfer pearlescent film and a preparation method thereof. Background technique [0002] Thermal transfer printing uses dot printing to print the pattern on the surface of the film. The printed pattern is rich in layers, bright in color, ever-changing, small in color difference, and good in reproducibility. It can achieve the effect of the designed pattern and is suitable for mass production. [0003] In the prior art, the pearlescent film is only made of light colors, and the printed pattern is beautiful, but the overall disadvantage is that it is not prominent enough and has no focus. People hope to find a better way. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a colorful thermal transfer pearlescent film with good pattern gloss and brightness, prominent focus and exquisite picture. ...
