Problems solved by technology

Since the current UV-curable screen printing snowflake ink used for cigarette packs is light yellow after printing and drying, it will affect the coloring effect of the previous printing ink, making it difficult for the printer to grasp; and this color will also increase with the length of time the printed matter is placed. It gradually becomes darker, which seriously affects the product quality; especially when printing on white cardboard, this disadvantage is more obvious

Abstract

The invention relates to novel ultraviolet-cured silk-screening snow printing ink which is characterized by being prepared from the following components: tripropylene glycol diacrylate, 1, 6-hexanediol diacrylate, trimethylolpropane triacrylate, polyaldehyde resin, poly-n-butyl methacrylate, poly{2-hydroxyl-2-methul-1-[4-(1-methyl vinyl)phenyl] acetone}, polyurethane acrylate, an organic silicon defoamer, a polyether organic silicon flatting agent, an active amine-assisted optical initiator and a wax powder. The printing ink printed and dried is still ultraviolet-cured silk-screening snow printing ink which is transparent and not yellowed as standing time of a printing material goes on and is good in adhesive force. The printing ink is particularly suitable for being used on a white paperboard or offset print light color ink and overlaid on silk-screening UV gloss oil and a silk-screening UV thick film to print, and is strong in adhesive force. Moreover, the printing ink detonated and rocketed is proper in pattern thickness, so that a transparent third-dimensional effect on a pattern of the printing material is obtained.

Description

Technical field [0001] The invention relates to an ultraviolet light curing silk printing snowflake ink. Background technique [0002] UV-curable silk screen snowflake ink is a process of printing the ink on the pattern surface of the printed matter through a printing machine, and then detonating the flower to solidify to show a crystal clear texture like a snowflake in winter. It is a crystallized and fission type special process ink. Since the UV-curable silk screen snowflake ink currently used for cigarette packs is light yellow after printing, it will affect the color forming effect of the previous printing ink, making it difficult for the printer to grasp; and this color will also increase with the length of the printing time. Gradually become deeper, seriously affecting the quality of the product; especially when printing on white cardboard, this drawback is more obvious. Summary of the invention [0003] In view of the problems in the prior art, the purpose of the present ...
