Described are cuprophthalocyanine type compounds represented by formula [1] in the form of the free acid
(wherein D is a cuprophthalocyanine radical; B is an alkylene group of 2 to 4 carbon atoms or a phenylene group which may have one or two carboxyl group(s) or sulfonic acid group(s) as a substituent(s); R is a lower alkyl group or a lower alkoxy-lower alkyl group; X is a carboxyl group or a carbamoyl group and combines with the 3- or 4-position of the pyridine ring; / is 1, 2 or 3; m is 0, 1 or 2; n is 1 or 2; and the sum of /, m and n is 2, or 4) as well as a method for dyeing cellulosic fiber materials using the said compounds.
The present invention relates to a recording solution which is characterized in containing a copper phthalocyanine compound represented by the following formula (I)
(In the formula(I), PC is a copper phthalocyanine skeleton; B is a C2∼C4 alkylene group or a phenylene group which may be substituted with carboxyl group(s) or with sulfonic acid group(s); R is a lower alkyl group or a lower alkoxy lower alkyl group; M is hydrogen atom, an alkali metal or an alkali earth metal; l is 1∼3; m is 0∼2; and n is 1 or 2 with a proviso that (l + m + n) is 2∼4).
The recording solution of the present invention is a recording solution which gives image of high concentration and clear color tone having a good storage stability, particularly in terms of water resistance.
本发明涉及一种记录溶液,其特征在于含有下式(I)表示的铜酞菁化合物
(在式(I)中,PC 是铜酞菁骨架;B 是 C2∼C4 亚烷基或亚苯基,可被羧基或磺酸基取代;R 是低级烷基或低级烷氧基; M 是氢原子、碱金属或碱土金属; l 是 1∼3; m 是 0∼2; n 是 1 或 2,但 (l + m + n) 是 2∼4。)
本发明的记录溶液是一种能产生高浓度图像和清晰色调的记录溶液,具有良好的储存稳定性,尤其是防水性。
