ABSTRACT:
A carpet and carpet tile resistant to the growth of Gram negative, Gram positive and fungal organisms which contains a polymeric non-plasticized PVC tuftlock precoat, fusion bonding adhesive, or secondary backing which has incorporated in it a phosphoric acid ester or its salt of the general formula: ##STR1## wherein R and R' are alkyl, oxyalkyl, polyoxyalkyl, aryl, aralkyl or alkaryl groups of C.sub.1 to C.sub.24, and one of R or R' can be H; X is a Group I metal ion, Group II metal ion, transition metal ion, or NY.sub.1 Y.sub.2 Y.sub.3 Y.sub.4, where Y.sub.1-4 are hydrogen, a hydrocarbon of C.sub.1 to C.sub.24, or a hydroxyalkyl group of C.sub.1 to C.sub.24 ; and there is at least one free hydroxyl group; and when X is NY.sub.1 Y.sub.2 Y.sub.3 Y.sub.4 or a Group I metal ion, n is 1, when X is a Group II metal ion, n is 2; and when X is a transition metal, n is equal to the valence of the metal.
