1. Phthalocyanine pigment has become a type of organic pigment, which not only has excellent heat resistance, light resistance, migration resistance, but also

Comprehensive application performance such as weather resistance, as well as advantages such as easy production and low cost, currently there is no chemical substance that can be extracted

Replacing it, its production accounts for 1/4 of organic pigment production. The varieties of phthalocyanine pigments used in plastic coloring are blue and green. Phthalocyanine

Pigment blue 151, pigment blue 153, and pigment green 7 have become the standard colors for plastic coloring.

Phthalocyanine pigments and their metal phthalocyanines have homogeneous polycrystalline properties, meaning that the same compound can generate multiple crystals with different structures. Homogeneous multiple

The phenomenon of crystallinity exists to varying degrees in many compounds, but is more typical in phthalein pigments. Except for the various products of phthalocyanine pigments

In addition to differences in melting points, these physical properties are also reflected in crystal shape, density, surface color, and reflection of light, which are similar to those of phthalocyanine pigments

The application performance of plastics is closely related. So studying and understanding these knowledge is of practical significance. Phthalocyanine materials are currently known to have

Eight crystal forms (a, B, Y, δ， e. I, X, R). But the crystal form used as a pigment is only.. B. y. Among them, especially a β*** Commonly used,

The stability of phthalocyanine pigments depends on their crystal form, with type B being stronger and type being weaker. A-type instability is not sufficient to withstand the processing temperature of plastic molding,

It will transform into a stable type. To avoid this situation, the type can be stabilized by adding 0.5-1 chlorine atoms or by adding others

Special stable substances are used to treat the crystalline surface and stabilize it,

Blue green varieties for plastic coloring

Application characteristics of CAS registration number structure type for varieties

Pigment blue 15:0 [147-14-8] CuPc unstable type, red light blue

Pigment blue 15:1 [147-14-83] Low chlorinated CuPc stable crystal form, red light blue

Pigment Blue 15+3 [147-14-867] CuPe Stable β Pin Li, green light blue

Flag material green 7 [1328-53-6] (CuPeC115-16 polychlorinated copper phthalocyanine)

Pigment Green 36 [14302-13-7] (CuPe) CI10Be6 Chlorobromo copper phthalocyanine

2.1 Blue phthalocyanine pigment

① C.I. Pigment Blue 15 CI Structure Number: 74160; CAS registration number: [147-14-8] Structural formula:

Color characterization: Pigment Blue 15 is a metastable crystalline copper phthalocyanine. The crystal stability of this pigment is poor, and it can dissolve in high temperatures or aromatic hydrocarbons

There will be a change in crystal form in the agent, transforming into a stable B-type (green light). Compared to pigment blue 15+3, pigment blue 15 shows a red light blue phase,

The color is bright and the coloring power is also high.
