Title: Foamed pigmented emulsions for the backcoating of loosely structured fabrics

Abstract: A foamed pigmented thermosetting aqueous emulsion useful for the backcoating of loosely structured fabrics, especially those made of polypropylene fibers, is provided based on the following components: 1. an aqueous emulsion copolymer of 5% to 40% ethylene, from 1% to 10% of reactive monoethylenic monomer comprising monoethylenic monomer carrying the ##STR1## group, such as acrylamide, and the balance consisting essentially of vinyl ester of saturated monocarboxylic acid, such as vinyl acetate; 2. mineral filler providing a pigment to binder ratio of at least 0.5:1, the filler having an alkaline character; and 3. surfactant for stabilizing the emulsion.
