The invention relates to a production process for leather for painting. The modern leather picture does not adopt the advanced production process for leather products, has a poor manufacturing method, a complex manufacturing process and single style, has no storage stability, and has high possibility of fading. The leather for painting is prepared by the steps of soaking in water, removing meat, degreasing, liming and removing hair, removing lime, softening, soaking in acid, tanning, extracting alkali after tanning, drying, painting, coating, shaping, mounting and obtaining the finished product, so that the leather has storage stability and is not damaged by worms when being placed for a long time. Painting adopts different painting methods of Chinese painting and oil painting, so that different styles are shown. The leather subjected to painting is treated, so the leather is anti-oxidant and is not faded along with the time. Chromium is not used in the tanning process, so environmental pollution is little.
