Patent ID: 7335613

Claim:
A treated fiber substrate having a surface, wherein at least a portion of the surface is treated with a finish, wherein the finish comprises at least one antimicrobial composition comprising a metal complexed with a polymer, wherein the metal is selected from copper, silver, gold, tin, zinc and combinations thereof; and, wherein the polymer comprises monomer residues selected from residue A, residue B, residue C and combinations thereof; with the proviso that the polymer contains no more than 99.5 wt % of monomer residues of residue B; wherein residue A is wherein residue B is wherein residue C is wherein X is an unsaturated or aromatic heterocycle having at least one hetero atom selected from N, O and S; c is 0 or 1; R 1 is selected from H, CH 3 and —CO 2 R 4 ; where R 4 is selected from H, CH 3 , C 2 H 5 , a C 3 -C 24 alkyl; R 2 is selected from H, CH 3 , C 2 H 5 , phenyl, —CH 2 CO 2 R 5 and —CO 2 R 5 ; where R 5 is selected from (I)-(V), where R 11 is selected from H, methyl and phenyl; n is an integer from 1 to 20; Y is selected from OH, SO 3 Z and X; where Z is selected from H, sodium, potassium and NH 4 + ; with the proviso that when the polymer contains 0 wt % of monomer residues of residue B and 0 wt % of monomer residues of residue C, R 2 is —CH 2 CO 2 R 5 or —CO 2 R 5 , R 5 is (V) and Y is X; R 3 is selected from H, methyl, phenyl, sulfonated phenyl, phenol, acetate, hydroxy, a fragment O—R 1 , where R 1 is as defined previously, —CO 2 R 12 and —CONR 6 R 7 ; where R 6 and R 7 are independently selected from H, methyl, ethyl, C(CH 3 ) 2 CH 2 SO 3 Z, where Z is as defined previously, C 3 -C 8 alkyl and a combined ring structure and R 12 is selected from H, CH 3 , C 2 H 5 and C 3 -C 24 alkyl; R 8 and R 9 are independently selected from hydrogen, methyl, ethyl and C 3 -C 4 alkyl; R 10 is selected from C 1 -C 8 alkyl, C 2 -C 8 alkenyl, C 6 -C 10 unsaturated acyclic, C 6 -C 10 cyclic, C 6 -C 10 aromatic, C 2 -C 4 alkylene oxide and poly (C 2 -C 4 alkylene) b oxides; where b is an integer from 2 to 20.
