Description
本発明は、非水系顔料分散剤及び顔料組成物に関する。非水系溶媒中に顔料を分散させる場合、その分散工程で分散剤を分散浴に投入するが、この際に良好な作業性を得るため、また優れた塗膜を得るため、投入した顔料が分散浴中に速やかに均一に分散してその分散状態が安定して維持されること、また得られる塗膜に色調のばらつきが少ないことが要求される。特に近年のように、より優れた色再現性を有する塗膜を得るため、顔料として粒子径が数百ｎｍ以下の微粒子のものを用いる場合においては、上記の要求が強い。本発明はかかる要求に応える非水系顔料分散剤及びこれを用いた顔料組成物に関する。 The present invention relates to a non-aqueous pigment dispersant and a pigment composition. When dispersing the pigment in a non-aqueous solvent, the dispersing agent is added to the dispersion bath in the dispersion step. At this time, in order to obtain good workability and to obtain an excellent coating film, the added pigment is dispersed. It is required that the dispersion is quickly and uniformly dispersed in the bath and the dispersion state is stably maintained, and that the obtained coating film has little variation in color tone. In particular, as in recent years, in order to obtain a coating film having more excellent color reproducibility, the above-described demand is strong when a pigment having a particle diameter of several hundred nm or less is used as a pigment. The present invention relates to a non-aqueous pigment dispersant that meets such requirements and a pigment composition using the same.
従来、前記のような非水系顔料分散剤としては、例えば、１）ポリカルボン酸とポリオールとを構成単位とし且つ該ポリオールの５０重量％以上がビスフェノールのアルキレンオキシド付加物であるポリエステル樹脂（例えば特許文献１参照）、２）二価カルボン酸とポリエチレングリコールとの縮合物を一価アルコールでエステル化したもの（例えば特許文献２参照）、３）アミノ基と反応する官能基を有する有機色素とアミンを反応させたもの（例えば特許文献３参照）、４）芳香族環にポリエーテルを結合したもの（例えば特許文献４参照）、５）テトラカルボン酸化合物にポリカプロラクトンを結合したもの（例えば特許文献５参照）等が提案されている。 Conventionally, as the non-aqueous pigment dispersant as described above, for example, 1) a polyester resin having polycarboxylic acid and polyol as constituent units and 50% by weight or more of the polyol is an alkylene oxide adduct of bisphenol (for example, patent) 2) A product obtained by esterifying a condensate of a divalent carboxylic acid and polyethylene glycol with a monohydric alcohol (see, for example, Patent Document 2), 3) an organic dye and an amine having a functional group that reacts with an amino group (For example, see Patent Document 3), 4) those in which a polyether is bonded to an aromatic ring (see, for example, Patent Document 4), and 5) those in which polycaprolactone is bonded to a tetracarboxylic acid compound (for example, Patent Document) 5)) has been proposed.
ところが、かかる従来の非水系顔料分散剤には、もともと分散性が不充分であったり、また当初は相応の分散性を示してもそれが安定して維持されなかったり、更には分散剤の量のわずかな変動によって得られる塗膜の色調がばらついたりする等の問題がある。
本発明が解決しようとする課題は、良好な分散性を示し、またそれが安定維持され、更に得られる塗膜が色調の再現性に優れる非水系顔料分散剤及び顔料組成物を提供する処にある。 The problem to be solved by the present invention is to provide a non-aqueous pigment dispersant and a pigment composition that exhibit good dispersibility, that are stably maintained, and that the resulting coating film has excellent color tone reproducibility. is there.
しかして本発明者らは、前記の問題を解決するべく研究した結果、かかる非水系顔料分散剤としては、特定の三成分を重縮合したポリエステルから成るものを用いるのが正しく好適であることを見出した。 Accordingly, as a result of studies conducted by the present inventors to solve the above-mentioned problems, it is found that it is correctly preferable to use a non-aqueous pigment dispersant made of polyester obtained by polycondensation of specific three components.
