Abstract

A method for treating leather characterized by applying to a fully tanned leather and treated with a fatty liquid and in a dry state, on one side only an aqueous dispersion having a pH of 2 to 6.5 and containing at least 5% in weight approximately but not more than 20% by weight of a water insoluble linear addition polymer of unsaturated molecules and 0.5 to 8% by weight of a surfactant, the polymer having a second order apparent transition temperature not higher at 38º C and the dispersed polymer particles having a surface medium between 250 and 1,300 angstroms, the condition that the impregnation is effected (1) to distribute at least about 90% of the polymer through at least 15% of the polymer. % but not more than about 40% of the thickness of the leather when treating only one side of a split leather or the flesh side of any leather, or (2) to penetrate through the corium my nor and deposit polymer until the action of the corium minor with the corium major when treating only next to the grain of a leather.
