Definitions
- the present invention relates to a method for producing a pigment dispersion and an actinic ray curable inkjet ink composition, and more specifically, for an actinic ray curable inkjet containing a cationic polymerizable monomer, a photoacid generator, a pigment and a dispersant.
- the present invention relates to a method for producing a pigment dispersion used for ink preparation, and an ink-jet ink composition using the same.
- inkjet recording methods can easily and inexpensively form images, and thus have been applied to various printing fields such as photo printing, various types of printing, marking, special printing such as color filters, etc.
- the need for quick-drying printing inks is growing due to cost and diversity of recording media.
- actinic radiation curable inkjet ink has relatively low odor and less VOC (volatile organic solvent) problem than solvent-based ink, and can record on non-absorbable recording media.
- VOC volatile organic solvent
- it has been attracting attention.
- an active light curable ink there is a radical polymerization type and a cationic polymerization type.
- the cationic polymerization type is not subject to the inhibition of polymerization by oxygen compared to the radical polymerization type, so it must be carried out in an inert atmosphere. It has been attracting attention because of its advantages, such as no restrictions and the relatively low odor.
- pigment dispersion is an important issue in inkjet inks compared to conventional paints.
- the dispersion since it is necessary to uniformly eject droplets at a higher speed than a fine nozzle, if the dispersion is unstable, the emission becomes unstable, which is a fatal problem as an inkjet ink. Therefore, it is necessary to ensure the storage stability for a long time as well as the dispersion stability of the pigment. Therefore, in pigment dispersion, in order to ensure dispersion stability, a polymer dispersant that dissolves in a solvent vehicle is used as a dispersant, and the polymer dispersant is strongly adsorbed at the adsorption point on the pigment surface.
- a pigment derivative is a compound in which a polar group such as a sulfonic acid group is introduced into a pigment skeleton, and it is disclosed that treatment using this is effective for dispersion stability of the pigment (for example, (See Patent Documents 1 to 3.)
- the cationic polymerizable monomer is a vehicle and the pigment dispersion in the system of the pigment adsorbed with the pigment derivative and the polymer dispersant is excellent in storage stability and filterability, the ink does not change even after ink formation. It was very difficult to obtain a pigment dispersion with good storage stability and light emission.
- pigment derivatives are Since it has an oleophilic polar group, it has the property of being easily dissolved or peeled off in a cationic polymerizable monomer having a high affinity between the monomer and the pigment derivative.
- the pigment derivative has a role of promoting adsorption between the pigment surface and the polymer dispersant in the monomer by the polar group. However, if excessive dispersion energy is applied to the pigment surface, the pigment derivative is detached from the pigment surface. The polymer dispersant is also released.
