  It is known that a reactive compound represented by an acrylate compound easily undergoes a polymerization reaction by an active species generated from a polymerization initiator by heating or irradiating active energy rays to form a reaction cured product. .

  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 colorant can be reduced by ejecting the required amount of ink droplets when necessary when 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 viscosity has a great influence on the printing stability and other image quality obtained compared to ink for other printing methods such as gravure and offset.

  In recent years, there has been a demand for an active energy ray-curable ink-jet ink that can be printed at a higher speed, that is, reactively cured in a short time, in order to improve productivity. As one of the countermeasures, a plurality of reactive acrylic groups are substituted. A reactive compound such as an acrylate compound 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, there has been proposed an active energy ray curable inkjet ink using an acrylate compound and a vinyl ether compound having different reactivity (Patent Document 3). However, when an acrylate compound and a vinyl ether compound are used in combination, there is a concern that unreacted monomers remain. Moreover, acrylate compounds are rich in reactivity and storage stability is bad.

  In order to improve the storage stability, an active energy ray-curable inkjet ink using a reactive compound having a (meth) acryl group and a vinyl ether group in the same molecule has been proposed (Patent Document 4).

Furthermore, by using vinyl ether group-containing (meth) acrylic acid esters (for example, (meth) acrylic acid-2-vinyloxyethyl, (meth) acrylic acid-4-vinyloxybutyl etc.) as a reactive diluent, Moreover, a curable resin composition excellent in curability has been proposed, and its application to inkjet ink has been shown (Patent Document 5). However, there is still room for improvement in curability.

Specific examples of the alkylene group in R ^{3 to} R ⁶ include, for example, a methylene group, an ethylene group, a propylene group, and a butylene group, preferably a methylene group and an ethylene group, and more preferably a methylene group. And ethylene group.

  Specific structures are shown in Table 1 below, but the structure of the reactive compound (A) of the present invention is not limited thereto.

  The reactive compound (A) of the present invention is expressed in the same molecule as a (meth) acrylic group [an acrylic group and a methacrylic group are collectively referred to as “(meth) acrylic group”. The same applies below. And a vinyl ether group. By having this basic structure, it is a compound having a normally conflicting function that the viscosity of the ink does not increase while being highly reactive.

  In addition, having a vinyl ether group is also superior in that it has a low viscosity as compared with reactive compounds such as acrylate compounds having two to three (meth) acrylic groups having a similar structure.

  Furthermore, the present compound has a low viscosity compared to the non-added polymerizable composition only by adding a small amount to the polymerizable composition comprising the radical polymerizable compound (B) and the radical polymerization initiator (C). The point which improves sclerosis | hardenability is also excellent, keeping.

  The reason why the reactive compound (A) of the present invention is preferable is that not only the curing rate accompanying the polymerization reaction is extremely fast, but also low viscosity, excellent storage stability and the reactive compound (A). It can also be mentioned that this reaction is easy.

  The reactive compound (A) of the present invention includes an ester condensation reaction using an acid as a catalyst, an esterification reaction between a carboxylic acid and an alcohol using a dehydrating agent, a reaction using an acid chloride, and described in JP-A No. 2001-220364. It can be obtained by using a general organic synthesis reaction such as a transesterification reaction using a palladium-containing compound as a catalyst.

  The acid catalyst that can be used in the synthesis of the reactive compound (A) of the present invention is an organic or inorganic strong acid, and is not particularly limited, but mineral acids and partially neutralized salts thereof, heteropoly acids, organic sulfonic acids A halogenated acetic acid, a Lewis acid, an acidic zeolite carrying an organic sulfonic acid, an activated carbon carrying an organic sulfonic acid, and the like.

  Specific examples of the mineral acid include sulfuric acid, hydrochloric acid, nitric acid, phosphoric acid, boric acid and the like.

  Of these acid catalysts, sulfuric acid, hydrochloric acid, nitric acid, phosphoric acid, methanesulfonic acid, benzenesulfonic acid, p-toluenesulfonic acid, and activated carbon carrying an organic sulfonic acid are preferred.

  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 induction heating by irradiation with microwaves is preferable. In the induction heating method using microwave irradiation, the desired reaction temperature can be reached in a short time, and therefore, the generation of by-products that can occur at the time of temperature rise can be suppressed.

  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 microwave energy or is difficult to absorb, non-patent literature (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.
