Abstract

The invention relates to printing ink special for photographic paper identification printing and a production process for the printing ink. The printing ink is prepared from the following raw materials in percentage by weight: 8 to 12 percent of pigment, 14 to 27 percent of polyvinyl chloride resin, 6 to 11 percent of modified polyamide resin, 25 to 32 percent of cyclohexanone, 15 to 20 percent of butyl acetate, 4 to 9 percent of low-boiling-point solvent, 0.002 to 0.005 percent of dibutyl phthalate (DBP), 9 to 15 percent of filler, 1 to 3 percent of surfactant and 1 to 3 percent of antistatic agent. The printing ink has bright color, fine and smooth quality, high tinting strength, high combination degree with the photographic paper, does not lose color and decolor in the processing and using process, has high color stability, is difficult to fade, meets the high-temperature flushing requirement, has excellent friction resistance and high water resistance, does not influence the photosensitive of the colored photographic paper, does not generate chemical reaction with the flushing liquid medicine, and does not pollute the flushing liquid medicine.

Description

technical field [0001] The invention relates to an ink, in particular to a special ink for color photo paper logo printing. Background technique [0002] Color photographic paper is a photosensitive material coated with silver halide emulsion on a paper base coated with polyethylene resin. Photosensitive chemical properties. [0003] Printing ink is a substance used to form graphic information in the printing process. It plays a very important role in the printing process and directly determines the tone, color, and clarity of the image on the printed matter. The characteristics of printing ink include ink fineness, transparency, adhesion, fluidity, viscosity, viscosity, etc. The printability of ink mainly includes viscosity, adhesion, thixotropy, and drying. [0004] With the continuous development of printing technology, the types of printing inks are also increasing, according to the printing method can be divided into: [0005] 1. Toppan printing ink: a type of ink us...
