摘要： The present invention provides aqueous matte coating compositions comprising a binder component B) and a polymeric duller component A) composed of particles of one or more multi-stage copolymer or single stage crosslinked (co)polymer, e.g. crosslinked t-butyl (meth)acrylate, the duller component particles A) having an average diameter of 1-20 µm. Components A) and B) are compatible. Preferably, the duller component A) is acrylic; more preferably, components A) and B) are acrylic. The aqueous compositions provide matte coatings having haptic or feel (soft touch) properties, film and appearance properties, including burnish resistance and low color loss.

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含水酸官能的丙烯酸或乙烯基共聚物的水性肉用涂料组合物，并且基于聚合物中羧酸的当量为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外皮或鞣制的皮革以及由其制成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皮革和鞣制皮革，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中是有价值的。
