[0157] Preparation of transparent ink

[0158] Table 2 shows the raw materials used to prepare the clear ink. According to the compounding described in Tables 3-6, a polymerizable monomer, a photopolymerization initiator, a polymerization inhibitor, and an organic solvent were slowly added to a reaction container, and the obtained liquid mixture was stirred. Next, after adding a surface tension adjusting agent to the above-mentioned mixed liquid, it was shaken by a shaker for 6 hours to prepare an ink. The obtained ink was filtered through a PTFE filter with a pore diameter of 0.5 microns to remove dust and coarse particles, and used as an evaluation ink. In addition, the addition and mixing order of the raw material for obtaining the said mixed liquid may differ.

[0160] Modulation of color ink

[0161] 15 parts by weight of the organic pigment, 7.5 parts by weight of the pigment dispersant, and 77.5 parts by weight of DPGDA were stirred with a high-speed mixer or the like until they became uniform. Next, the obtained mill base was dispersed for about 1 hour with a horizontal sand mill to prepare a pigment dispersion.

[0162] To the previously prepared pigment dispersion, a mixed solution of a polymerizable monomer, a photopolymerization initiator, a polymerization inhibitor, and an organic solvent was slowly added so as to be formulated in Table 7, and the obtained mixed solution was stirred. The compounding amount of DPGDA described in Table 7 is a numerical value which also includes the amount of DPGDA in the pigment dispersion. Next, after adding a surface tension modifier to the above-mentioned mixed solution, it was shaken by a shaker for 6 hours to prepare a color ink. The obtained color ink was filtered through a PTFE filter ...

[0164] Preparation of white ink

[0165] As a pigment, 50 parts of Tipaque CR-60 (titanium oxide treated with aluminum, primary particle size 210 nm, manufactured by Ishihara Sangyo Co., Ltd.), 2.5 parts of pigment dispersant, and 47.5 parts of DPGDA were stirred with a high-speed mixer until uniform . Next, the obtained mill base was dispersed for about 2 hours with a horizontal sand mill to prepare a pigment dispersion.

[0166]A mixed solution of a polymerizable monomer, a photopolymerization initiator, a polymerization inhibitor, and an organic solvent was slowly added to the previously prepared pigment dispersion so that the formulation described in Table 7 was obtained, and the obtained mixed solution was stirred. The compounding amount of DPGDA described in Table 7 is a numerical value which also includes the amount of DPGDA in the pigment dispersion. Next, after adding a surface tension modifier to the above mixed liquid, it was shaken by a shaker for 6 hours to prep...

Abstract

Provided is an active energy ray-curable inkjet ink which contains an organic solvent having a boiling point of 140-300 DEG C and a polymerizable monomer containing 2-(2-vinyloxyethoxy)ethyl acrylate, and which contains the organic solvent in an amount of 0.1-10% by weight based on the total weight of the ink. This ink has extremely high curability and ejection stability, and exhibits excellent adhesion to various bases. Consequently, this ink is suitable for use in inkjet printing.

Description

technical field [0001] The present invention relates to an active energy ray curable inkjet ink which has very high curability and discharge stability, and has adhesiveness to various substrates. Background technique [0002] The inkjet printing method refers to a printing method in which fine droplets of an ink composition from an inkjet head fly and land on a substrate to be printed to form images and characters on the substrate. This inkjet printing method is characterized in that a plate is not required for printing. The electrophotographic method is widely known as a printing method that does not require a plate. However, compared with the electrophotographic method, the inkjet printing method is superior in the initial cost of the device, the running cost at the time of printing, the size of the device, high-speed printing characteristics, and the like. [0003] Conventionally, various types of ink compositions such as solvent-based, water-based, and oil-based ink co...
