Abstract

A coating composition comprising a single-phase mixture of first and second polymers that are different polymers.

Claims

exact text as granted — not AI-modified

1 . A coating composition comprising a single-phase mixture of first and second polymers that are different polymers, 
 wherein said first polymer is a polyvinyl acetal, cellulosic polymer, polyester, polycarbonate, epoxy resin, rosin polymer, polyketone resin, vinyl polymer, or maleic anhydride ester copolymer,    said second polymer is a polyvinyl acetal resin, cellulosic resin, vinyl polymer, or maleic anhydride-ester copolymer, and    said coating composition further comprising a polyisocyanate crosslinking agent in an amount of at least 10% based on total dry weight of said crosslinkable hydrophilic polymer binder.    
   
   
       2 . The coating; composition of  claim 1  wherein said polyisocyanate crosslinking agent is present in an amount of from 10% to 30% based on total dry weight of said crosslinkable hydrophilic polymer binder.  
   
   
       3 . The coating; composition of  claim 1  further comprising a tertiary amine or transition metal catalyst.
