The present invention relates to an active energy ray-curable inkjet ink excellent in storage stability.

  Reactive compounds typified by acrylate compounds and vinyl ether compounds are known to easily undergo a polymerization reaction and form a cured product by active species generated from a polymerization initiator by heating or irradiation with active energy rays. ing.

  Applications using these reactive compounds are diverse, and one of them is active energy ray-curable ink.

  Conventionally, active energy ray curable inks have been used for offset printing and silk screen printing, but the cost per color can be reduced by ejecting the required amount of ink droplets when necessary during printing. In recent years, demand for active energy ray-curable inks for ink jet printing has been increasing from the point that on-demand printing is possible without requiring a plate. Active energy ray curable inks for inkjet printing include ultraviolet curable inkjet inks that are cured with ultraviolet rays, and are environmentally friendly and fast due to the reduction of volatile solvents compared to conventional water-based or solvent-based non-curable inks. In recent years, it has been attracting attention because of its high dryness, odor reduction, and ink-absorptive substrate printing, and high substrate selectivity, and patents have been disclosed (Patent Documents 1 and 2).

  Ink-jet ink is also characterized in that the effect of viscosity on printing stability and other obtained image quality is very large compared to other printing method inks such as gravure and offset.

  In recent years, printing at a higher speed for improving productivity, that is, an active energy ray-curable ink-jet ink that cures in a short time has been desired, and one of the countermeasures is a reaction in which a plurality of reactive substituents are substituted. May be used. However, the greater the number of acrylic group substitutions, the higher the viscosity of the ink, causing a problem that the ink ejection performance from the head is significantly reduced.

  As a method for improving the curability without increasing the viscosity of the ink, an active energy ray-curable ink-jet ink in which an acrylate compound and a vinyl ether compound are used in combination has been proposed. Reference 3).

  In order to improve storage stability, active energy ray-curable inkjet inks using reactive compounds having an acrylic group and a vinyl ether group in the same molecule have been proposed, but they are still insufficient in terms of curability. Yes (Patent Document 4).

  When synthesizing the reactive compound (A) of the present invention, a heat transfer method using an external heat source is usually used. As a heating means for synthesizing more efficiently, a method of heating by irradiation with microwaves is preferable.

  Examples of the microwave include 2450 ± 50 MHz, 5800 ± 75 MHz, and 24125 ± 125 MHz, which are designated frequency bands in Japan, and preferably 2450 ± 50 MHz.

  A microwave generator that can generate a frequency used for commercial use can be used, and there is no restriction such as a single mode, a multimode, a magnetron type, or a cavity type. For example, a microwave reactor μ reactor (made by Shikoku Keiki Kogyo Co., Ltd.) having an oscillation frequency of 2450 ± 30 MHz and an output power of 760 W can be used.

  When microwave heating is used when synthesizing the reactive compound (A) of the present invention, a nonpolar solvent that does not absorb or hardly absorb microwave energy may be added.

  Here, as a solvent that does not absorb or hardly absorbs microwave energy, non-patent literature (from B. L. Hayes, Microwave Synthesis: Chemistry at the Speed of Light, CEM Publishing, Mattews NC, 2002). From the values of dielectric loss (tan δ) of various solvents at a wave frequency of 2450 MHz and 25 ° C., the ease of absorbing microwave energy for the various solvents is defined.

  Among them, a solvent having a tan δ of 0.1 or less is generally described in the following non-patent literature (C. Olive Kappe, Controlled Microwave Heating in Modern organic Synthesis) as a solvent that does not absorb or hardly absorb microwaves. Specific examples include chlorobenzene, chloroform, acetonitrile, ethyl acetate, acetone, tetrahydrofuran, dichloromethane, toluene, xylene, hexane, cyclohexane and the like.

  The reason why these solvents are preferable is that by using a nonpolar solvent that does not absorb or hardly absorb microwave energy, the absorption of microwaves of alcohol and carboxylic acid, which are reaction substrates, is not hindered and efficient. It can be mentioned that it becomes a reaction. In addition, in the ester condensation reaction, it is desirable to use a solvent that forms an azeotrope with water produced by this reaction, and an organic solvent that azeotropes water to promote dehydration.

  A solvent having a boiling point of 80 ° C. to 120 ° C. is preferable as the solvent. Specific examples include benzene, toluene, and cyclohexane, and more preferred are toluene and cyclohexane.

  Although the specific structure of the reactive compound (A) of this invention is shown below, this invention is not limited to them. In the table, H represents a hydrogen atom, and Me represents a methyl group.

Is preferable because it is excellent. The organic pigment is preferably a fine pigment having an average particle diameter of 10 to 150 nm as measured by laser scattering. When the average particle diameter of the pigment is less than 10 nm, the light resistance is lowered due to the small particle diameter, and when it exceeds 150 nm, it is difficult to maintain stable dispersion, and the pigment is likely to precipitate.

  The organic pigment can be refined by the following method. That is, a mixture comprising at least three components of an organic pigment, a water-soluble inorganic salt that is at least 3 times the weight of the organic pigment, and a water-soluble solvent is made into a clay-like mixture, and is kneaded strongly with a kneader or the like and then refined.

  Examples of the water-soluble inorganic salt include sodium chloride and potassium chloride. These inorganic salts are used in the range of 3 times by weight or more, preferably 20 times by weight or less of the organic pigment. When the amount of the inorganic salt is less than 3 times by weight, a treated pigment having a desired size cannot be obtained. On the other hand, if the amount is more than 20 times by weight, the washing process in the subsequent step is great, and the substantial amount of the organic pigment is reduced.
