AI Technical Summary

Problems solved by technology

Although the pigment has better water resistance and light resistance, it must be combined with an appropriate dispersant and adhesive agent. In addition, the pigment has a larger particle size, so it is more prone to precipitation and aggregation. And clog the inkjet head, reducing the printing quality

Abstract

A combination of high chroma multi-colour dyestuff and the ink-jet ink for the chromatic colour ink-jet print is disclosed. The combination of dyestuff include: a. direct blue dyestuff 199,acidic blue dyestuff 9, direct blue dyestuff 87 b. active red dyestuff 158, active red dyestuff 159, acidic red dyestuff 92 c. acidic yellow dyestuff 23, direct yellow dyestuff 86. The combination dyestuff has not only the light and water resistance but also the unique viscosity and interfacial force. It can improve the quality of the print because of the wide colour gamut and high quality colour imagery.

Description

technical field [0001] The invention relates to a combination of multicolor dyes with high chroma and an ink-jet ink composition containing the combination of dyes. Background technique [0002] Generally speaking, for the requirements of color inkjet printing, it is necessary to have a wide color range and ideal mixed colors, such as blue or red. The combination of cyan ink, magenta ink, yellow ink and black ink is called primary dye-set. Secondary dye-set refers to other colors that do not contain the first-level dye combination coloring material, but are obtained through the mixing and matching of the first-level dye combination coloring material. [0003] In fact, for color inkjet printing, a better ink combination, its ink characteristics and printing quality must meet the following requirements: wear resistance (good crusting resistance), stability (goodstability), unique viscosity (proper viscosity), unique surface tension (proper surface tension), high color satura...
