The invention relates to a production technology of contrast-effect automobile seat cushion leather. The protection technology comprises the steps of liming: dissolving Na2S, NaHS and lime into water in a mass ratio of 1:1:2 to form a liming alkali liquor, reacting fur with the liming alkali liquor in a liquor ratio of 100:100 for 6 h, adding the liming alkali liquor step by step to enable the liquor ratio to increase to 100:200, and continuously reacting for 12 h; retanning: for every 100 parts of fur, adding 100 parts of water, 1 part of a pre-fatting agent and 3 parts of a chrome tanning agent or a chrome-free tanning agent, reacting at the normal temperature for 1 h, adding 2 parts of sodium formate, reacting at the temperature of 40 DEG C for 1 h, and controlling the pH in a range of 3.6-4.0; and finishing: the finishing comprises the steps of roller coating of a bottom layer, embossing, spraying of a color layer, roller coating of an effect layer and spraying of a top layer. The leather produced through the technology is soft, fine in grain side, full in hand feeling, elastic, safe and environment-friendly and has characteristics of wear resistance, folding endurance, light resistance, color migration resistance and the like; and ornamental and pleasant characteristics of the leather are added due to roller coating of the effect layer, and the rigid and non-flexible appearance of ordinary automobile seat cushion leather is changed.
