Example Embodiment

[0116] Example 1

[0117] The resin varnish 1 for ink is used, a pigment, a photopolymerization initiator, a polymerization inhibitor, etc. are mixed, and it is ground with three rollers to obtain the ultraviolet curable ink of the present invention processed into four colors (yellow, red, blue, and black). The ink formulation is shown in Table 2.

Example

[0124] Example 2-4, Comparative Example 1

[0125] Except for using resin varnish 2-5 for ink, the same method as in Example 1 was used to obtain the ultraviolet curable ink of the present invention and the ink of the comparative example processed into four colors. Among them, the formulation of blue ink is shown in Table 3.

[0126] Example 1

[0127] (C) Evaluation of physical properties of the resulting ink

[0128] Using inks processed into 4 colors (yellow, red, blue, and black), the surface layer of OK is coated (57.5) on the R704 single-paper printing machine manufactured by Rorand, which is equipped with an ultraviolet irradiation device (120W, 3 metal halide lamps). kg / A, manufactured by Oji Paper Co., Ltd.) After printing 3000 sheets at a speed of 8000 sheets / hour, various comparative tests of suitability were carried out, namely (1) wide scale value of water volume, (2) rubber roller and rubber The swelling property of the cloth, (3) the retention of the ink...

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...
