Description

本発明は、堅牢性が高く、機能性染料として有用なフタロシアニン化合物に関する。   The present invention relates to a phthalocyanine compound having high fastness and useful as a functional dye.

フタロシアニン化合物は堅牢性の高い染料又は顔料としてだけでなく、機能性色素としても幅広く用いられている。特にα位にアルキル、アリール、ヘテロ環スルホニル基の置換したフタロシアニン化合物は、CD−Rなどの光情報記録材料の記録層の色素としての利用が報告されている(例えば、特許文献1参照。)。α位に置換基としてスルホニル基を有するフタロシアニン化合物は好ましい吸収特性を有するが、従来知られている化合物はいずれも油溶性であって、用途・用法において限定されるものであった。またβ位にスルホニル基の置換した水溶性フタロシアニン化合物も知られているが(例えば、特許文献2参照。)、これらは会合体に由来するブロードな吸収しか得られなかった。
特開2003−94828 特開2004−323511
Phthalocyanine compounds are widely used not only as fast dyes or pigments but also as functional dyes. In particular, a phthalocyanine compound substituted with an alkyl, aryl, or heterocyclic sulfonyl group at the α-position has been reported to be used as a dye in a recording layer of an optical information recording material such as CD-R (see, for example, Patent Document 1). . Phthalocyanine compounds having a sulfonyl group as a substituent at the α-position have preferable absorption characteristics, but all of the conventionally known compounds are oil-soluble and are limited in use and usage. In addition, water-soluble phthalocyanine compounds substituted with a sulfonyl group at the β-position are also known (see, for example, Patent Document 2), but only broad absorption derived from the aggregates was obtained.

合成中間体A(1.26g、4mmol)のエチレングリコール溶液(10mL)にCuCl2(134mg、1mmol)を加え、100℃に加熱した。反応混合物にDBU(1.52g、10mmol)を添加し、100℃で10時間撹拌した。反応混合物を塩酸で酸性化し、LiClを添加するとフタロシアニンの粗生成物が析出した。ここで得られた粗生成物をSephadex G−15を担体としたカラムクロマトグラフィーにより精製し、参考化合物2の混合物を67mg(収率5%)で得た。 CuCl 2 (134 mg, 1 mmol) was added to an ethylene glycol solution (10 mL) of synthetic intermediate A (1.26 g, 4 mmol) and heated to 100 ° C.

本発明で得られたα−スルホニル置換フタロシアニン化合物は、すべて水溶性染料であり、水溶液中でモノマーに由来するシャープな分光吸収スペクトルを与えることを大きな特徴とする。従来知られている油溶性のα−スルホニル置換フタロシアニン化合物では、水への溶解度が低く水溶液として利用することができない。一方、水溶性β−スルホニル置換フタロシアニン化合物では会合体に由来するブロードな分光吸収スペクトルしか得られない。   The α-sulfonyl-substituted phthalocyanine compounds obtained in the present invention are all water-soluble dyes, and are characterized by giving a sharp spectral absorption spectrum derived from a monomer in an aqueous solution. Conventionally known oil-soluble α-sulfonyl-substituted phthalocyanine compounds have low water solubility and cannot be used as an aqueous solution. On the other hand, with a water-soluble β-sulfonyl-substituted phthalocyanine compound, only a broad spectral absorption spectrum derived from the aggregate can be obtained.
