[Also in Division C3] Materials such as leather, metals, wood, concrete, masonry, asbestos, and cement slabs are coated with a spontaneously cross-linking polymer of an acylamino methylene carbamate of the formula: in which R is a haloalkyl or halocycloalkyl radical and R1 is H or CH 3 and, optionally, one or more comonomers, e.g. unsaturated acids and esters, amides and nitriles thereof, vinyl ethers, vinyl esters, vinyl ketones, vinyl or vinylidene halides, aromatic vinyl compounds, heterocyclic vinyl compounds, conjugated dienes, olefines, and divinyl or divinylidene compounds. Coatings are suitably obtained using latexes of the polymers, and in one Example the polymers are used as binders for casein-based surface lacquers for dressing leather.
