Abstract
Abstract Poromeric plastic coated fabrics containing embedded therein microspheres disposed in natural or synthetic clustered domains each constituted by a matrix insoluble in the coating composition, the clustered domains adjacent to one another but spatially separated horizontally and vertically to provide substantially uniform microporosity throughout the coating.
