Description

本発明は、顔料や油溶性染料等の様々な不溶性色材(以下、単に「色材」という)に対して高い吸着性を示す、色材用分散剤の吸着部位の形成に利用可能な化合物(モノマー)に関する。   The present invention is a compound that can be used to form an adsorption site of a dispersing agent for a colorant, which exhibits high adsorptivity to various insoluble colorants (hereinafter simply referred to as “colorants”) such as pigments and oil-soluble dyes. (Monomer).

従来より、色材は、溶媒または樹脂等の媒体(以下、単に「媒体」という)に分散され、インクや塗料として使用されている。このような用途においては、色材が媒体中に均一に分散されている必要があり、一般に、高分子分散剤や界面活性剤などの分散剤が併用されてきた。   Conventionally, a color material is dispersed in a medium such as a solvent or a resin (hereinafter simply referred to as “medium”) and used as ink or paint. In such applications, it is necessary that the colorant is uniformly dispersed in the medium, and generally, a dispersant such as a polymer dispersant or a surfactant has been used in combination.

色材用の分散剤は、主に色材に対して吸着性を持つ「吸着部位」と、媒体への親和性を有する「分散部位」とで構成され、それぞれの部位は、色材あるいは媒体に合わせて設計できることから、様々な分散剤が報告されている。   The dispersing agent for the color material is mainly composed of an “adsorption site” having an adsorptivity to the color material and a “dispersion site” having an affinity for the medium, and each site is a color material or a medium. Therefore, various dispersants have been reported.

例えば、特許文献1では、吸着部位として窒素含有マクロモノマーを用いた色材分散剤が、また、特許文献2では、塩基性基を有する顔料誘導体を有する吸着モノマーと、カルボキシル基を有し媒体に親和性の高い分散ポリマーの混合物を用いた色材分散剤が提案されている。   For example, in Patent Document 1, a colorant dispersant using a nitrogen-containing macromonomer as an adsorption site is used, and in Patent Document 2, an adsorption monomer having a pigment derivative having a basic group and a carboxyl group as a medium. A colorant dispersant using a mixture of dispersion polymers having high affinity has been proposed.

しかしながら、これら従来の分散剤の構造中の吸着部位(あるいは、その形成成分である吸着モノマー)は、色材への吸着性が低く、分散剤として使用した場合に満足できる効果を示さないという問題点があった。従って、本発明の課題とするところは、色材への高い吸着性を示し、高分子分散剤等の分散剤における色材への吸着部位の形成に利用可能な新規なモノマーを提供することにある。   However, the adsorbing site (or the adsorbing monomer that is a component of the adsorbing component) in the structure of these conventional dispersants has a low adsorptive property to the coloring material and does not exhibit a satisfactory effect when used as a dispersing agent. There was a point. Accordingly, an object of the present invention is to provide a novel monomer that exhibits high adsorptivity to a color material and can be used for forming an adsorption site on the color material in a dispersant such as a polymer dispersant. is there.

本発明者らは、上記課題を解決すべく鋭意検討した結果、色材用分散剤を形成する際に特有な構造のモノマーを用いることで、色材に対する高い吸着性能を示す吸着部位を持つ色材用分散剤の形成が可能になることを見出して、本発明を完成するに至った。   As a result of intensive studies to solve the above-mentioned problems, the present inventors have used a monomer having a specific structure when forming a colorant dispersant, so that a color having an adsorption site exhibiting high adsorption performance for a colorant. The inventors have found that a dispersant for a material can be formed, and have completed the present invention.

A benzene ring which may have a group, Z 1 , Z m , Z n and Z p each independently represents either a hydrogen atom or a polymerizable functional group, and Z 1 , Z m , at least two of Z n and Z p is a polymerizable functional group.)

まず、本発明のピリダジン誘導体を色材用分散剤の形成に用いた場合に、色材に対する高い吸着性能を示す吸着部位が形成される理由について説明する。本発明のピリダジン誘導体は、分子内にC=OおよびNを含有するため、これを色材用分散剤の形成に用いるとその構造中にC=O及びNを導入でき、これらは色材が持つ親水基と水素結合することが可能である。これに加えて、本発明のピリダジン誘導体は、分子内に不飽和結合やベンゼン環を複数有しており、分子の平面性が高いことから、色材とのπ−π相互作用が増大され、色材に対して強い吸着性を示す。   First, the reason why an adsorption site exhibiting high adsorption performance with respect to a color material is formed when the pyridazine derivative of the present invention is used for forming a dispersant for the color material will be described. Since the pyridazine derivative of the present invention contains C═O and N in the molecule, it can be introduced into the structure when it is used to form a dispersant for a colorant. It can hydrogen bond with the hydrophilic group it has. In addition to this, the pyridazine derivative of the present invention has a plurality of unsaturated bonds and benzene rings in the molecule, and since the planarity of the molecule is high, the π-π interaction with the coloring material is increased, Shows strong adsorptivity to coloring materials.

また、本発明のピリダジン誘導体は、その構造中に複数の重合性官能基を有するが、当該重合性官能基の存在によって、色材を分散する際に用いられる種々の媒体に合わせて様々な分散部位を適宜に形成させることができる。本発明のピリダジン誘導体を構成する重合性官能基としては、アクリル基やメタクリル基等の重合性を有するものが好ましく、例えば、下記(I−a)〜(II−b)で示される官能基が挙げられる。さらには、これらの重合性官能基は連結基を介して結合されていてもよい。その際の連結基としては、例えば、アミド基、エステル基、ウレタン基、ウレア基、アルキレン基、フェニレン基、−O−、−NR1−及び−NHCH(CH2OH)−からなる群が挙げられる。ただし、R1は水素原子、アルキル基、フェニル基、アラルキル基を表す。 In addition, the pyridazine derivative of the present invention has a plurality of polymerizable functional groups in its structure, but the presence of the polymerizable functional group allows various dispersions in accordance with various media used when dispersing the coloring material. A site | part can be formed suitably. The polymerizable functional group constituting the pyridazine derivative of the present invention is preferably a polymerizable functional group such as an acryl group or a methacryl group. For example, functional groups represented by the following (Ia) to (II-b) are: Can be mentioned. Furthermore, these polymerizable functional groups may be bonded via a linking group. Examples of the linking group at that time include a group consisting of an amide group, an ester group, a urethane group, a urea group, an alkylene group, a phenylene group, —O—, —NR 1 —, and —NHCH (CH 2 OH) —. It is done. R 1 represents a hydrogen atom, an alkyl group, a phenyl group, or an aralkyl group.

Figure 2015067576

本発明者らの検討によれば、上記に挙げた重合性官能基のうち、少なくとも1種をその構造中に2個以上備えることで、本発明のピリダジン誘導体は、前述した吸着機能(水素結合、もしくはπ−π相互作用による色材への吸着機能)を阻害することなく、これを用いて形成した色材用分散剤に良好な分散部位を付加することができる。従って、本発明のピリダジン誘導体を色材用分散剤の形成材料に用いることで、吸着部位として優れた性能を有する分散剤を製造することが可能となる。   According to the study by the present inventors, the pyridazine derivative of the present invention has the above-described adsorption function (hydrogen bond) by providing at least one of the polymerizable functional groups listed above in its structure. In addition, a good dispersion site can be added to the colorant dispersant formed using this without inhibiting the adsorption function to the colorant due to the π-π interaction). Therefore, by using the pyridazine derivative of the present invention as a material for forming a colorant dispersant, it is possible to produce a dispersant having excellent performance as an adsorption site.

本発明者らの検討によれば、本発明のピリダジン誘導体を構成する前記重合性官能基は、前記一般式(1)中のAr1〜Ar4のメタ位またはパラ位に付設するのが好ましい。その理由は、重合性官能基をオルト位に配置した場合、分子内で生じる立体障害によって、該重合性官能基に分散部位を付加する際の反応性が低下したり、付加した分散部位がピリダジン誘導体の持つ前記した色材への高い吸着機能を阻害するおそれがあるので好ましくない。よって、重合性官能基の位置は、分散部位を付加する際における反応性を確保するとともに、色材への吸着性能が損なわれることがないように、メタ位またはパラ位に付設するのが好ましい。特に、分子の中心から最も離れたパラ位に配置するのがより好ましい。 According to studies by the present inventors, the polymerizable functional group constituting the pyridazine derivative of the present invention is preferably attached to the meta position or para position of Ar 1 to Ar 4 in the general formula (1). . The reason for this is that when the polymerizable functional group is arranged in the ortho position, the steric hindrance generated in the molecule reduces the reactivity when adding a dispersion site to the polymerizable functional group, or the added dispersion site is pyridazine. This is not preferable because there is a risk of hindering the high adsorption function of the derivative to the above-described color material. Therefore, the position of the polymerizable functional group is preferably attached to the meta position or the para position so as to ensure the reactivity when adding the dispersion site and not impair the adsorption performance to the coloring material. . In particular, it is more preferable to arrange in the para position farthest from the center of the molecule.

本発明のピリダジン誘導体は、従来より公知の方法で合成可能であり、例えば、次のようなスキームで合成できる。   The pyridazine derivative of the present invention can be synthesized by a conventionally known method. For example, it can be synthesized by the following scheme.

〔ピリダジン誘導体の色材への吸着率の測定〕
本発明で目的としている色材分散剤の構造中の吸着部位における高い性能は、その形成成分である吸着モノマーの吸着性能に依存する。このことは、本発明のピリダジン誘導体の性能として、色材への高い吸着性が求められることを意味しており、その効果を認定するためには色材への吸着性能を確認する必要がある。そこで、本発明では、ピリダジン誘導体の色材への吸着率の測定を、分光光度計(日立社製)を用いて行った。測定の際における吸着率の測定方法、使用する色材・溶媒、ピリダジン誘導体の混合比率等の条件は以下の通りである。
[Measurement of adsorption rate of pyridazine derivative to coloring material]
The high performance at the adsorption site in the structure of the colorant dispersant aimed at in the present invention depends on the adsorption performance of the adsorption monomer as the forming component. This means that the performance of the pyridazine derivative of the present invention requires high adsorptivity to the color material, and it is necessary to confirm the adsorptivity to the color material in order to recognize the effect. . Therefore, in the present invention, the adsorption rate of the pyridazine derivative to the colorant was measured using a spectrophotometer (manufactured by Hitachi).
