Abstract
The present invention is directed to a method of treating tanned leather to improve its dyeing characteristics while still retaining desired grain break and grain strength.

The syntan includes a copolymer of a carboxylic acid monomer and a vinyl ester monomer, such as, vinyl acetate. The retanning method of the present invention provides wide process latitude.
