The blending amount of the pigment can be arbitrarily determined depending on the kind of the pigment used and the like, but is usually 0.1 to 15% by mass, preferably 0.5 to 10% by mass of the ink composition.
本発明のインクジェット印刷用インク組成物においては、顔料分散剤として、１分子中に２個以上のアミド基を有し且つ数平均分子量が２,０００〜１５,０００であるポリエステルポリアミド樹脂を用いる。この顔料分散剤の配合量は、使用する顔料の種類等により決定されるが、通常はインク組成物の０.１〜１５質量％であり、好ましくは０.５〜１０質量％である。 In the ink composition for inkjet printing of the present invention, a polyester polyamide resin having two or more amide groups in one molecule and having a number average molecular weight of 2,000 to 15,000 is used as a pigment dispersant. The blending amount of the pigment dispersant is determined depending on the kind of the pigment used and the like, but is usually 0.1 to 15% by mass, preferably 0.5 to 10% by mass of the ink composition.
代表的な顔料分散剤は酸末端ポリエステル樹脂と１分子中に２個以上のアミノ基を有するポリアミン化合物とを反応させることにより製造される。例えば、ソルスパース３２０００、ソルスパース３２５００、ソルスパース３２６００、ソルスパース３３５００、ソルスパース３４７５０、ソルスパース３５１００、ソルスパース３７５００、ディスパービック９０７７等を挙げることができる。 A typical pigment dispersant is produced by reacting an acid-terminated polyester resin with a polyamine compound having two or more amino groups in one molecule.

なお、アミド基が１分子中１個以下の場合には顔料分散性が悪いので好ましくない。また、数平均分子量が２,０００未満の場合には顔料分散安定性が低下し、数平均分子量が１５,０００を超える場合にはインク中への分散性が低下する傾向がある。 In addition, when the number of amide groups is 1 or less per molecule, the pigment dispersibility is poor, which is not preferable. Further, when the number average molecular weight is less than 2,000, the pigment dispersion stability is lowered, and when the number average molecular weight exceeds 15,000, the dispersibility in the ink tends to be lowered.
また、本発明のインクジェット印刷用インク組成物は電導度調整剤を含有することができ、電導度調整剤の配合量は通常はインク組成物の０．１〜１０質量％であり、好ましくは０.５〜５質量％である。 Moreover, the ink composition for inkjet printing of this invention can contain a conductivity adjusting agent, and the compounding quantity of a conductivity adjusting agent is 0.1 to 10 mass% normally of an ink composition, Preferably it is 0. 0.5 to 5% by mass.
