Abstract

The invention discloses a photo-curing offset ink which is prepared from the following raw materials in parts by weight: 15-20 parts of pigment, 10-15 parts of epoxy acrylate, 5-15 parts of polyester acrylic resin, 25-35 parts of alkyd resin, 3-5 parts of benzophenone, 1-3 parts of propoxide glycerol methacrylate ester, and 1-5 parts of TX-10. The photo-curing offset ink is simple to burden, fast to cure, good in film-filming property, low in cost and applicable to large-scale industrial application.

Description

technical field [0001] The invention relates to the technical field of printing ink, in particular to a formulation of photocurable ink. Background technique [0002] Photocurable ink is UV ink. UV is the abbreviation of Ultraviolet Rays in English, that is, ultraviolet light. Ultraviolet (UV) is invisible to the naked eye. It is a section of electromagnetic radiation other than visible violet light, with a wavelength in the range of 10-400nm. UV ink refers to ink that is instantly cured by UV light irradiation. [0003] From the perspective of printing process, UV ink has fast fixation speed, good conjunctival performance, good adhesion to various printing materials, and better scratch resistance, abrasion resistance, acid and alkali resistance than ordinary inks. Therefore, Although its price is much more expensive than ordinary ink, it is still widely used. [0004] Compared with traditional ink printing, UV printing does have great advantages, but its popular applica...
