Properties and stability

1. Basic properties

refers to a class of dyes with a phthalocyanine structure. It is generally an organic complex containing metal atoms such as copper or chromium, zinc, nickel, manganese, etc., but there are also some that do not contain metal atoms.

Storage method


Synthesis method

2. Brief description of production method

Most phthalocyanine dyes are further processed from the pigment phthalocyanine. For example: copper phthalocyanine can be directly light-fast emerald blue after sulfonation and neutralizationGL, copper phthalocyanine is chlorosulfonated and then combined with (β-hydroxyethylsulfoneyl)aniline Condensation can produce active emerald blueKN-G.


3. Purpose

Phthalocyanine dyes have bright colors and good color fastness, and are mainly used for dyeing and printing fabrics such as cotton, linen, viscose and silk.
