The earliest metal complex dyes were chromium complex acid dyes with salicylic acid as the component, pioneered by BASF Company in 1912. In 1915, Ciba Company developed ortho – and ortho – dibasic azo copper complex direct dyes; In 1919, the company developed a 1:1 chromium complex acidic dye. In 1936, German IG Company launched metal complex ice dyeing dyes that underwent coupling color development and then complexation treatment. In the 1950s, they successively developed metal complex dispersed dyes, metal complex leather dyes, and metal complex solvent dyes that can be used for coloring paints, inks, and aliphatic and aromatic non-polar solvents. In 1960, they were also made into metal complex dyes that can form covalent binding with cellulose fibers, It can be said that metal complex dyes have been involved in the entire field except for vat dyes and cationic dyes, with the azo type accounting for the majority and being the most important type.
Metal complex dyes greatly improve their dyeing performance due to the presence of metal ions in the dye molecules. This dye has a full and bright color, good covering power and dyeing fastness, and is widely used in dyeing. In leather dyeing, both spray dyeing and drum dyeing can improve dyeing quality, and it is also a popular dye among leather dyeing workers.
Our company, SUNRISE CHEM, can supply metal complex solvent dyes. Such as solvent red 21, solvent orange 62, solvent blue 70, solvent black 27 etc.
