Problems solved by technology

The above covered inks are all printed on the surface of the object, which is extremely easy to fall off and fade, and the connection is extremely unstable
[0004] In addition, most of the thermal transfer inks on the market do not have the function of changing color, which also brings great inconvenience to people's use.

Abstract

The invention relates to a variable-color heat transfer printing ink which comprises 20-45 parts of offset diluting resin, 15-35 parts of ink compound, 17-33 parts of gummy oil and 25-35 parts of variable-color toner. The variable-color sublimation heat transfer printing ink can be directly converted from the solid dye into a gas phase through liquification so as to infiltrate among the molecular chain structures of the fiber and petrochemical product. After the ink is used for coloration, the printed material does not any hand feeling or unevenness phenomenon, and the ink can not damage the printed material and is environment-friendly. After being used for coloration, the ink has the advantages of very high clarity, obvious multilayer effect, very high stability, no shedding or fading and high connection stability, has the variable-color function, and can be used for printing trademarks, patterns or characters on clothing packages, brands or other products. In a strong-weak light alternate location, the printed characters, patterns or trademarks can display different colors, thereby preventing the product from being imitated, and maintaining the reputation of the product. Thus, the ink has very wide application range.

Description

technical field [0001] The invention belongs to the technical field of thermal transfer printing, in particular to a color-changeable thermal transfer printing ink and a preparation method thereof. Background technique [0002] Printing ink is a paste-like colloid formed by uniform dispersion and mixing of colorants, binders, fillers and other materials, and there are many types. The colorant gives the printed product a rich and colorful tone; the linking material acts as the carrier of the colorant, and also acts as a binder to fix the colorant on the surface of the substrate; the filler gives the ink proper properties, so that the ink can meet the printing suitability of various printing processes . More specifically, the binder is a viscous fluid. Its function is firstly as a carrier of the colorant, mixing and connecting solid particles such as powdery colorant; secondly, as a binder, the colorant can finally be It is fixed on the surface of the substrate to achieve th...
