Abstract

The present invention provides an aqueous composition useful for treating fabric comprising (i) a complex of silver ion with a copolymer and (ii) a dispersed amine-functional softener, wherein said copolymer comprises (a) 60-95 wt % polymerized units of one or more monomer X, wherein said monomer X is an ethylenically unsaturated compound having a substituent group selected from an unsaturated or aromatic heterocyclic group having at least one nitrogen atom; and (b) 5-40 wt % polymerized units of one or more monomer Y, wherein said monomer Y is an ethylenically unsaturated compound selected from carboxylic acids, organosulfuric acids, sulfonic acids, phosphonic acids, esters comprising polymerized units of ethylene oxide, and mixtures thereof. Also provided is a method of treating fabric comprising contacting said fabric with the composition of claim 1 at pH from 3 to 7.

Claims

exact text as granted — not AI-modified
1 . An aqueous composition useful for treating fabric comprising
 (i) a complex of silver ion with a copolymer and   (ii) a dispersed amine-functional softener,   wherein said copolymer comprises   (a) 60-95 wt % polymerized units of one or more monomer X, wherein said monomer X is an ethylenically unsaturated compound having a substituent group selected from an unsaturated or aromatic heterocyclic group having at least one nitrogen atom; and   (b) 5-40 wt % polymerized units of one or more monomer Y, wherein said monomer Y is an ethylenically unsaturated compound selected from carboxylic acids, organosulfuric acids, sulfonic acids, phosphonic acids, esters comprising polymerized units of ethylene oxide, and mixtures thereof.   
     
     
         2 . The composition of  claim 1 , wherein said composition has pH from 3 to 7. 
     
     
         3 . The composition of  claim 2 , wherein monomer X is N-vinylimidazole. 
     
     
         4 . The composition of  claim 1 , wherein said amine-functional softener is a silicone polymer. 
     
     
         5 . A method of treating fabrics comprising contacting said fabric with the composition of  claim 1  at pH from 3 to 7.
