Antimicrobial acid-catalyzed coating compositions

Abstract

The antimicrobial acid-catalyzed coating composition of the invention is an acid-catalyzed coating composition formulated with at least one antimicrobial agent to provide antimicrobial activity to the coating composition and an article coated therewith.

1 . A coating composition comprising an acid-catalyzed coating composition comprising one or more aminoplast resins, one or more backbone resins which contain functional groups that will react with the aminoplast resin or resins, at least one acid catalyst, and at least one organic antimicrobial agent. 
   
   
       2 . The coating composition of  claim 1 , wherein the antimicrobial agent comprises at least one a silver-based antimicrobial agent. 
   
   
       3 . The coating composition of  claim 1 , wherein the coating composition comprises:
 about 40-about 60% by weight of non-volatiles of said at least one backbone resin;   about 20-about 40% by weight of non-volatiles of at least one crosslinker;   about 60-about 70% by weight of volatiles of at least one carrier;   about 2-about 4% by weight of non-volatiles of said at least one catalyst; and   about 0.01-about 1% by weight of non-volatiles of said at least one antimicrobial agent.   
   
   
       4 . An antimicrobial acid-catalyzed coating composition comprising at least one antimicrobial agent, a plasticizer, at least one acid catalyst and about 20-about 30% by weight of non-volatiles of nitrocellulose. 
   
   
       5 . An article coated with the antimicrobial acid-catalyzed coating composition of  claim 1 . 
   
   
       6 . The coating composition of  claim 1 , wherein the antimicrobial agent comprises about 0.01%-about 0.5% by weight of non-volatiles. 
   
   
       7 . The coating composition of  claim 4 , wherein the coating composition comprises:
 about 40-about 60% by weight of non-volatiles of at least one backbone resin; about 20-about 40% by weight of non-volatiles of at least one crosslinker; about 60-about 70% by weight of volatiles of at least one carrier; about 2-about 4% by weight of non-volatiles of the at least one acid catalyst; and about 0.01-about 1% by weight of non-volatiles of the at least one antimicrobial agent.   
   
   
       8 . A coating composition comprising an acid-catalyzed coating composition comprising one or more aminoplast resins, one or more backbone resins which contain functional groups that will react with the aminoplast resin or resins, at least one acid catalyst, and at least one organic antimicrobial agent, wherein the acid catalyst is para-toluene sulfonic acid, phenyl acid phosphate or butyl acid phosphate. 
   
   
       9 . The coating composition of  claim 8 , wherein the coating composition comprises:
 about 40-about 60% by weight of non-volatiles of the one or more backbone resins; about 20-about 40% by weight of non-volatiles of at least one crosslinker; about 60-about 70% by weight of volatiles of at least one carrier; about 2-about 4% by weight of non-volatiles of the at least one acid catalyst; and about 0.01-about 1% by weight of non-volatiles of the at least one antimicrobial agent.   
   
   
       10 . The coating composition of  claim 1 , wherein the antimicrobial agent comprises about 0.25%-about 0.5% by weight of non-volatiles. 
   
   
       11 . The coating composition of  claim 4 , wherein the antimicrobial agent comprises about 0.01%-about 0.5% by weight of non-volatiles. 
   
   
       12 . The coating composition of  claim 8 , wherein the antimicrobial agent comprises about 0.01%-about 0.5% by weight of non-volatiles.
