Metal complex dyes are a special type of dye whose molecules contain coordinated metal atoms and possess a range of unique properties and applications. The following is a detailed introduction to metal complex dyes:

1. Definition:
-Metal complex dyes are dyes with coordinating metal atoms in their molecules, which can be formed by complexing with metal ions such as copper, cobalt, chromium, nickel, etc.
-It is not only soluble in organic solvents, but also in water, which makes it have a wider range of applications.

2. * * Type * *:
-In addition to acidic metal complex dyes, it also includes metal complex dispersed dyes, metal complex solvent dyes, etc.
-Among them, 1:2 metal complex dyes are a special type that are mainly soluble in organic solvents such as aromatics, esters, styrene, methyl methacrylate, and are almost insoluble in water.

3. * * Features * *:
-Metal complex dyes have unique high glossiness and transparency, excellent weather resistance and firmness.
-Compared to inorganic pigments, metal complex dyes are more easily dispersed, have strong permeability, and have bright colors.

4. * * Color tone * *:
-The main color tones of 1:2 metal complex dyes include yellow, orange, red, blue, black, and fluorescent red (peach red).

5. * * Application * *:
-Metal complex dyes are widely used in fields such as architectural decoration, wood coloring, hot stamping materials, leather dyeing, shoe polish dyeing, plastic spraying, printing ink, stationery ink, metal spraying, paint, glasses, packaging paper, aluminum foil paper, etc.

-Especially when mixed with polyester resin, polyoxyester resin, melamine resin, acrylic resin, amino resin, nitrocellulose varnish, etc., it performs well.
