摘要： A method of improving the strength, temper and water resistance of leather utilizing selected amphiphilic copolymers is provided. The amphiphilic copolymers are formed from a predominant amount of at least one hydrophobic monomer and a minor amount of at least one copolymerizable hydrophilic monomer. The method is particularly useful as a one step substitute for conventional retanning and fatliquoring treatment steps. In a preferred embodiment the amphiphilic copolymers also provide a significant degree of water resistance to the leather.

摘要： The present invention provides aqueous flesh coating compositions comprising one or more aqueous acid-functional acrylic or vinyl copolymer and from 0.03 and up to 1.0 equivalent, based on equivalents of carboxylic acid in the polymer, of one or more active compound chosen from an aminoguanidine, semicarbazide, dihydrazide, guanamine, hydrazine and a salt thereof. Further, the invention provides methods of applying the coating composition to leather crust or to tanned leather, and to the flesh coated leather or coated leather crust produced thereby. The leather crust and tanned leather produced by the invention, for example fleshcoated or finished leather, will emit greatly reduced levels of aldehydes over time and especially valuable in scrubbing aldehydes from perforated leather for automotive use.
摘要翻译： 本发明提供包含一种或多种酸性官能的丙烯酸或乙烯基共聚物水溶液的含水肉皮组合物，和基于聚合物中羧酸当量的0.03和至多1.0当量的一种或多种活性化合物，所述活性化合物选自氨基胍， 氨基脲，二酰肼，胍胺，肼及其盐。 此外，本发明提供了将涂料组合物施用于皮革皮革或鞣制的皮革以及由其制备的肉皮涂层皮革或涂覆的皮革外皮的方法。 由本发明生产的皮革外壳和鞣制皮革，例如肉皮或成品皮革，随着时间的推移，将大大降低醛的含量，特别是在从用于汽车用途的穿孔皮革洗涤醛时尤其有价值。
