Digital color ink-jet ink provided with 3D lines and suitable for shoe upper printing

Abstract

The invention provides digital color ink-jet ink provided with 3D lines and suitable for shoe upper printing. The digital color ink-jet ink is prepared from, by weight, an oligomer of a polymer or a copolymer containing a carboxylic acid group (COOH) 2%-25%, a monomer 35%-65%, a pigment 2%-10%, a photosensitive initiator 2%-10%, a solvent 2%-35%, and an additive containing a pigment dispersant or a property adjustment agent 5%-15%. The digital color ink-jet ink is acid-resistant, alkali-resistant and environmentally friendly, can be jetted to form stereoscopic line patterns within several seconds, the pigment color ink-jet ink can be rapidly cured by absorbing ultraviolet light and has good adhesive power, the usage rate of organic solvents is reduced by replacing the organic solvents permeating into a base material for adhesion in a photocuring adhesion mode, accordingly the harm of the organic solvents to the environment and human bodies is reduced, and the digital color ink-jet ink can be jetted on common shoe upper fabrics and can be also jetted on different materials such as glass, leather, plastic materials and advertising consumables, and stereoscopic patterns have the advantages of being foldable, twistable and deformation-free.

Description

technical field [0001] The invention relates to a digital color ink-jet ink with 3D texture and suitable for vamp printing. Background technique [0002] Traditional printing inks for shoe uppers can generally only print flat patterns, but cannot print lines with height and three-dimensional effects. However, the flat patterns sprayed by traditional shoe upper printing inks also have unbreakable shortcomings. Once the flat pattern printed on the upper is bent, cracks will appear in the pattern, resulting in damage to the texture pattern, affecting the appearance of the upper, and even shortening the service life of the shoe. Moreover, the ink used for traditional upper printing can only be printed on a specific surface. It can't be printed on glass, furniture, leather and other materials, which leads to its limited use and poor flexibility, and it can't be printed with various materials. Therefore, in view of the shortcomings of the above-mentioned technical problems in the...
