Abstract

The invention relates to a preparation method of color ink powder for printers, belonging to the field of pigments. The preparation method is simple in process and is easy to operate. The color ink powder is yellow ink powder which contains a yellow pigment, wherein the yellow pigment comprises the following components in parts by weight: 20-40 parts of La2O3, 10-40 parts of MoO3, 5-10 parts of Pr6O11 and 5-10 parts of Nd1.8Sm0.2O3. The color ink powder adopts an inorganic oxide as the pigment; and the yellow ink powder has bright color and stable properties, can still give play to functions stably after long-term storage and is especially suitable for vast quick printing.

Description

technical field [0001] The invention relates to a preparation method of color toner for printers, belonging to the field of pigments. Background technique [0002] The printed color is the light reflected by the paper, so the three primary colors of the pigment are the colors that can absorb RGB, which are cyan, magenta, and yellow, and they are the complementary colors of RGB. For example, if you mix yellow pigment and cyan pigment, because yellow pigment absorbs blue light and cyan pigment absorbs red light, only green light is reflected. This is the reason why yellow pigment plus cyan pigment forms green. [0003] Yellow toner for printers is one of the three primary color toners, usually composed of solvents, colorants, surfactants, pH regulators, driers and other necessary additives. However, the currently used yellow toner fades quickly and has poor color, which is not conducive to long-term storage and large-volume printing. Contents of the invention [0004] The ...
