Definitions
- the present invention relates to a low polymerization degree polycarboxylic acid dye.
- Polymeric dyes have high strength, good film formability, solvent resistance and processability, and have excellent migration and wet fastness. They are a new field of functional macromolecules and dye chemistry. Polycarboxylate-type dyes can not only impart water solubility to the dye due to the molecular weight of the carboxyl group, but are suitable for coloring natural fibers and leather products, and can be removed or amidated or esterified under certain conditions. It is a hydrophobic dye, and thus the synthetic fiber is colored. Therefore, the polycarboxylic acid dye has universal applicability and has important application value and prospect.
- Lewis et al. reacted aspartic acid with the double reactive dye C ⁇ active red 120 to form a tetracarboxylic acid dye, which was baked at 180-210 ° C for 1-2.5 minutes. The state reacts with the fiber to dye. However, the dye fixation rate is low and the dyeing temperature is also high (Lewis, AATCC, 1995, 536-544).
- USP3911 164, USP 6764541 copolymerize maleic anhydride with mercapto vinyl ether to obtain a copolymerized polymer, and then react with a dye to obtain a copolymerized macromolecular dye containing a carboxyl group, but the introduction of a copolymer group reduces the polymer
- the content of the acid anhydride is such that the amount of the dye grafted is lowered.
- polycarboxylic acid dyes are strong and easy to synthesize, and are a kind of dye with development prospects.
- polycarboxylic acid dyes especially the polymaleic acid type polycarboxylic acid which directly uses a polymaleic acid homopolymer as a macromolecular skeleton, an amide or ester bond as a bridging group, and an organic small molecule dye. Dyes have not been reported in the literature.
- the object of the present invention is to develop a new class of low-polymerization polycarboxylic acid dyes which directly use a polymaleic acid homopolymer as a macromolecular skeleton and an amide or ester bond as a bridging group to link small organic molecules.
- Dye suitable for dyeing and printing of leather, natural fiber and synthetic fiber; improving the color fastness of dye by increasing the binding force of dye to coloring matrix by means of the presence of polycarboxyl group.
- the dye synthesis process is simple, convenient to apply, and has broad application prospects.
- the present invention provides a class of low polymerization polycarboxylic acid dyes.
- the dye is a macromolecular skeleton of polymaleic acid, and is bridged by an amide or ester bond.
