Abstract
A sheet material having a microporous surface of elastomeric polyurethane is treated to produce a sheet, which has greater water-proofness and still transmits water vapor, by applying to it a coagulated layer of elastomeric polyurethane. Preferably the coagulated layer is produced by applying a pigmented polyurethane solution to the sheet while it is wet with a non-solvent. The coagulated layer may then be treated in various ways; e.g. it may be embossed or treated with a solvent to form a fused glossy moisture vapor-transmitting surface. The product is suitable for use as a leather substitute in shoe uppers.
