Abstract
Abstract A fabric coating comprising a carboxylated butadiene acrylonitrile polymer alone or in combination with a butadiene acrylonitrile-styrene polymer, zinc oxide as a curing agent pigment and optionally a thickener is disclosed. A fabric thus coated has the appearance of leather, is waterproof, oil-proof and useful for wearing apparel.
