<p>Embossable foam latex compositions prepared by dispersing into a foam latex from 20 to 150 parts by weight per hundred parts of latex solids of a powdered particulate material having a melting point in the range 90.degree. to 200.degree.C. Suitable powdered particulate materials include powdered PVC resins, polyolefins, waxes and the like. Embossing of foam-backed carpet or foam sheet material prepared from these latex compositions is readily accomplished by heating the foam structure to the melting temperature of the dispersed particulate material, then passing the foam through a cold embossing roll to chill and set the foam in place.</p> |
