Finishing leather with a synthetic carboxylated rubber dispersion

摘要

Leather is finished with a synthetic carboxylated rubber dispersion to which as much as 50% by weight of one or more oxides and/or hydroxides of divalent and/or trivalent metals may have been added, finishing being carried out by a process in which the carboxylated rubber dispersion is prepared by the emulsion feed method, with a conversion of more than 90%, in such a way that it contains from 20 to 60% by weight of carboxylated rubber which is soluble in dimethylformamide at room temperature.
