With the rapid development of modern technology and the gradual maturity of processing technology, pearlescent pigments play an increasingly important role in the processing of animal leather. From leather shoes to clothing, from various bags to cushion sofas, the decorative effect of pearlescent pigments has been valued by more and more people.

For animal leather, because of the different uses of leather and fur, there are different requirements for the properties of the colored layer. In general, in most cases, the coloration of pearlescent pigments should be carried out during the finishing stage after dyeing. The pearlescent pigment is added to the leather pigment paste at a ratio of 5% to 8%, and the pearlescent pigment sheet is mechanically or chemically fixed to the surface of the leather by the adhesion of the resin in the pigment paste to form a pearl leather surface coating. It is also possible to add 2% to 3% of pearlescent pigment to the casein finish, which also achieves the effect of pearlescent decoration.

They are lactic casein formed within hydrogen bonding between film and leather, thus divided into strong, not easy to fall off due to friction. Moreover, the film formed by the lactic casein is relatively heat-resistant and can be ironed, and the formed pearl layer has the advantages of strong gas permeability and strong water permeability. The coating is not eroded by organic solvents, with water as the medium, no pollution, no odor, and convenient operation steps.
