The pigment copper phthalocyanine solid solution and transparent dispersed ones which include that

摘要

As for this invention, as a host copper phthalocyanine (Pigment Blue 15; C.I. 74160), it regards the pigment solid solution which includes the pigment of the violet from the other blue as a guest. The desirable host, of copper phthalocyanine (the Pigment Blue 15:1), (the Pigment Blue 15:3) and (the Pigment Blue 15:6) is crystal form and especially crystal form. The single phase solid solution is desirable. This invention regards also dispersed ones which include the pigment derivative furthermore, as a pigment particle as these solid solutions and a rheology revised medicine. Especially, by comparison with the color filter which exists, the liquid crystal display which possesses the transmitted band which is improved in 44510nm (LCD) you can use for manufacturing the business color filter any dispersed things where the solid solution of the crystal lattice is desirable. In addition, the fact that it is claimed, production method of dispersed ones of this invention, solid solution itself, and is the use in order to color the high-molecular quantitative organic material.
