<P>PROBLEM TO BE SOLVED: To provide a monoazo pigment composition high in tinting strength, excellent in dispersibility and in crystal stability, and little in impurity content, more practically to provide a pigment composition that settles the problem that the crystal stability of monoazo pigment falls down when primary particle diameter thereof is made very fine, further is excellent in dispersibility even if the particle is very fine, also to provide a pigment dispersion excellent in dispersion stability and an inkjet ink excellent in dischargeability using the same. <P>SOLUTION: The pigment composition contains various monoazo pigments and monoazo pigment derivatives having various substituents. <P>COPYRIGHT: (C)2011,JPO&INPIT |
