Composite pigments, coloring compositions, and image recording substances |
摘要 |
A composite pigment of a bluish green color comprises copper phthalocyanine and aluminum phthalocyanine which are preferably in the form of a mixture or solid solution. The composite pigment can be produced by mixing copper phthalocyanine and aluminum phthalocyanine into a mixture and then converting said mixture into a pigment form. A coloring composition comprises at least a resin and a pigment which comprises copper phthalocyanine and aluminum phthalocyanine. The coloring composition can be produced by mixing copper phthalocyanine and aluminum phthalocyanine which have been independently comminuted, into a composite pigment, and then kneading the pigment and a resin such that the pigment is dispersed in the resin. An image recording substance is produced using the coloring composition. The image recording substance can be a dry developer of a fine powder form or a wet developer of a liquid form, an ink-jet ink, or a thermal transfer ink ribbon with the coloring composition coated on a film-shaped or sheet-shaped base material.
