Problems solved by technology

However, resins or 6-functional monomers are used in large quantities, and the viscosity is very high
Therefore, it is very difficult to spit out these inks through the existing inkjet heads, and it is necessary to invent ink compositions suitable for inkjet

Embodiment

[0058] Hereinafter, the present invention is further described in detail through examples, but the following examples do not limit the scope of rights of the present invention in any way. In addition, "part" in an Example means a "weight part."

[0059] (Preparation of Pigment Dispersion)

[0060] As described in Table 1, after mixing pigments, dispersing resins (resin-based pigment dispersants) and monomers, disperse them with a bead-type disperser (DCP mill) for 1 hour to obtain pigment dispersions A~AE. Dispersion was performed using Zr beads of a diameter of 0.3 mm at a volume filling rate of 75%.

[0061] In addition, the description of the dispersion resin used is described below in Table 1. DR-A, DR-B and DR-C are dispersion resins having a urethane skeleton, and DR-D and DR-E are polyesteramine-based Disperse resin.

[0062] (preparation of ink)

[0063] As shown in Table 2 and Table 3, the monomer mixed liquid was slowly added to 20 parts of each obtained pigment ...

Abstract

The invention is an active energy ray-curable inkjet ink composition. Specifically provided is a single pass-curable ink having high color reproducibility and high curing properties at the same time and having high dischargeability when used in printing at high frequency and high jetting speed, as compared with conventional ones. An active energy ray-curable inkjet ink composition contains a metal lake pigment of a rhodamine dye as a pigment, and the active energy ray-curable inkjet ink composition may contain 0.5 to 10% by weight of Pigment Violet 1, Pigment Violet 1:1, Pigment Violet 2, Pigment Violet 2:2, Pigment Red 81, Pigment Red 81:1, Pigment Red 81:2, Pigment Red 81:3, Pigment Red 81:4, Pigment Red 81:5, Pigment Red 169, or Pigment Red 173 as the metal lake pigment of the rhodamine dye based on the total weight of the ink.

Description

technical field [0001] The present invention relates to an active energy ray curable colored inkjet ink. Background technique [0002] Conventionally, active energy ray-curable inkjet inks are often mounted on high-speed printing type label printers (signage printers) due to their rapid drying compared with solvent-based inkjet inks. Or from the aspect of excellent substrate adhesion, it is often mounted on a flatbed printer (Flatbed printer) that can handle various substrates. Furthermore, it is being developed according to the application. [0003] These printers can cope with upsizing, thicker films, and higher densities by scanning the nozzles. In recent years, the technological progress of the nozzle has established the technology of the nozzle capable of ejecting fine liquid droplets at a high frequency. With the realization of this technology, inkjet printing, which is inferior in terms of productivity and image quality, has the advantages of digitalization and the...
