Abstract
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.

Dependent Claim
56 words
mineral filler providing a pigment to binder ratio of at least 0.5:1, said filler having a alkaline character; and 3. surfactant for stabilizing said emulsion; said aqueous emulsion having a viscosity of from 500 to 15,000 centipoises and being foamed to increase the volume thereof to an extent of from 0.5 to 4 times the original
Claim 5
Dependent Claim
19 words
volume. 2. A foamed pigmented emulsion as recited in claim 1 in which said mineral filler is calcium carbonate.
