Ultraviolet-ray solidified ink and printed matter using same

Abstract

The present invention provides a printing ink which has good printing adaptability and easy treatment property of oiliness printing ink and can be solidified and instantaneously dried by UV-ray and printed matter printed by said printing ink. Besides, it also provides a printing ink used in the UV-ray solidified printing method for continuously cover-printing UV-ray solidification transparent varnish on the printing ink, and also provides the printed matter with excellent production property and excellent glossiness and frictional resistance. By regulating its carrier components said printing ink has good oleophilicity, good printing adaptability, easy treatment property and UV-ray instantaneous solidification property.

Description

technical field [0001] The present invention relates to an ultraviolet curable ink used for printing on substrate materials such as paper or plastic film using a lithographic printing machine. [0002] Furthermore, it relates to a printed matter provided with high gloss and high abrasion resistance by overprinting clear varnish when printing using this ink. Background technique [0003] In printing using an oxidative polymerization drying type oil-based ink, since it takes time for the printed matter to dry, there is a problem of low working efficiency. As a solution to this problem, although UV-curable inks are used, oil-based inks do not have the properties suitable for lithographic printing. In addition, when using UV-curable inks in printing machines for oil-based inks, there are still rubber rollers. Problems such as swelling. [0004] In addition, as a method of reducing these problems, there is known a method of continuously overprinting an ultraviolet-curable trans...

AI Technical Summary

Problems solved by technology

[0010] 1) Due to the high viscosity of the main acrylic monomer used in the ink, the type and amount of solid resin used in combination are limited, making it difficult to obtain sufficient printing adaptability;

[0011] 2) The functionality of the main acrylic monomer is very low, and it is difficult to obtain sufficient ultraviolet curability;
