  • Publication number: 20150376412
    Abstract: The invention provides a black pigment composition capable of overcoming the drawbacks of carbon black pigments, which, when used as a toner colorant in particular, is able to reduce color shading over time and improve image qualities through an improvement in charging performances such as charge leakage and the like. The invention also provides a chromatic pigment composition able to reduce and correct the tinge of a carbon black pigment while improving fading stability, when the composition is added to a carbon black composition for electrophotographic toners. The black pigment composition contains, as essential pigments, a pigment P1 having a maximum absorption wavelength ?max (nm) within the range of 460??max?530 and a half-value wavelength (long wavelength side) of the absorption spectrum of 550 nm or more, and a pigment P2 having a maximum absorption wavelength ?max (nm) within the range of 600??max?700, as measured in the form of a dispersion in a solvent (methyl ethyl ketone).
