Phthalo Blue: bright colour, dye color strongly, has the high dispersion, high heat resistance, excellent solvent resistance and storage stability
 
It has many excellent performance. Such as high crystalline and stability, strong tinting for the Prussian blue several times, group of green, insoluble in most more than times solvent in heated to **0 degrees, and when, it doesn't happen, sublimation and chemical change, with bright blue, and good wear resistance and transparency. Now, not only used as colorants phthalocyanine youth, and is also used in organic semiconductor, light conductance photosensitive resin, the increasing of feeling agent, etc. Therefore, copper phthalocyanine blue become the largest output in organic material quite, use is the most extensive blue varieties. At present, the world market demand for it is increasing. Acid youth points type a and b type. Industry system of coarse crystallization of the blue phthalocyanine type b. This lack of turquoise tone of the blue phthalocyanine tinting strength. In order to made a material goods, must be the processing, pigment into type a.
