摘要： This invention relates to a process for modifying keratinous material, and, in particular, to a process for rendering the material resistant to shrinkage and to a process for imparting durable press characteristics to the material. This process comprises treating the material with a resin having at least two thiol groups per molecule and containing a radical of a polyhydric alcohol, bound to this radical, at least two poly(oxyalkylene) chains, at least two radicals of a thiolcontaining aliphatic carboxylic acid or of a thiol-containing aliphatic alcohol. As curing catalyst a sulfur-containing organic compound is used.
