Document Type and Number:
Japanese Patent JP7183712
Kind Code:
B2
Abstract:
To provide a squarylium pigment achieving both light fastness and dispersibility while having good dispersibility.SOLUTION: The squarylium pigment is represented by the general formula (1). The squarylium pigment is preferably used in a toner for electrophotography, an ink for an inkjet printer, an ink for a thermal printer and an ink for typographic, offset, flexographic, gravure and silk printing. The pigment has preferably diffraction peaks at least at Bragg angles 2θ (±0.2°) of 8.5°, 12.7°, 15.3°, 16.0°, 17.5°, 19.6°, 22.4° and 26.6° in an X-ray diffraction pattern by CuKα ray.SELECTED DRAWING: Figure 1
