The invention provides a pigment compound which improves characteristics of organic pigments, especially flowability and non-flocculation properties when added to the organic pigments. The pigment compound is represented in the form of a free acid by the following formula (I):
wherein D represents an organic pigment residue excluding azo and phthalocyanine pigment residues; R₁ represents a substituted or unsubstituted and saturated or unsaturated aliphatic hydrocarbon group having 1-10 carbon atoms or a substituted or unsubstituted aromatic hydrocarbon group having 6-10 carbon atoms; X represents a heterocyclic ring-substituted alkyl group, the alkyl group having 1-6 carbon atoms and being substituted on a carbon atom of a heterocyclic ring having at least one of nitrogen atom, oxygen atom and sulfur atom, or
in which Y represents a straight or branched alkylene group having 1-10 carbon atoms, R₂ and R₃ independently of one another represent a substituted or unsubstituted and saturated or unsaturated aliphatic hydrocarbon group having 1-20 carbon atoms or a substituted or unsubstituted aromatic hydrocarbon group having 6-20 carbon atoms, or both R₂ and R₃ are taken together with the adjacent nitrogen atom to form a heterocyclic ring having at least one nitrogen atom, and optionally an oxygen or sulfur atom; or R₁ is taken together with the adjacent nitrogen atom and the
to form a heterocyclic ring having at least two nitrogen atoms; m is a number of 0-3 with the proviso that m is a number of 1-3 when R₁ is an unsubstituted aliphatic hydrocarbon group; n is a number of 1-4; and a total of m and n is 1-5.
本发明提供了一种颜料化合物,它可以改善有机颜料的特性,尤其是添加到有机颜料中后的流动性和不絮凝特性。该颜料化合物以游离酸的形式用下式(I)表示:
其中,D 代表有机颜料残留物,不包括偶氮和酞菁颜料残留物;R₁ 代表具有 1-10 个碳原子的取代或未取代的饱和或不饱和脂肪族烃基,或具有 6-10 个碳原子的取代或未取代的芳香族烃基;X 代表杂环取代的烷基,该烷基具有 1-6 个碳原子,在杂环的碳原子上被取代,该杂环至少具有氮原子、氧原子和硫原子中的一个,或
其中 Y 代表具有 1-10 个碳原子的直链或支链亚烷基,R₂ 和 R₃ 相互独立地代表具有 1-20 个碳原子的取代或未取代的饱和或不饱和脂肪族烃基或具有 6-20 个碳原子的取代或未取代的芳香族烃基、或 R₂ 和 R₃ 与相邻的氮原子一起形成杂环,该杂环至少有一个氮原子,可选地还有一个氧原子或硫原子;或 R₁ 与相邻的氮原子和
R₁ 是未取代的脂族烃基时,m 的数值为 1-3;n 的数值为 1-4;m 和 n 的总和为 1-5。
