摘要： 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 tanned leather is contacted, preferably by immersion, in a float containing a syntan and a desired colorant. 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.
