The present invention provides a polycarboxylic acid dye with low polymerization degree, which is formed by using a macromolecule skeleton of polymaleic acid linked to an azo chromophore, an azo-metal complexation chromophore or an anthraquinone chromophore via a bridge group of amide or ester bond. The dye is useful for dyeing and printing leather, protein fiber, cellulose fiber and synthetic fiber.
