摘要:
A water reducible resin composition, a water reducible admixture of such resin with solvents and plasticizers, a water reduced form of such mixture suitable for a coating, and a coating prepared from such water reduced mixture. Said resin is required to be prepared from a balance of hydrophobic enhancing and hydrophilic enhancing monomers. Generally such hydrophobic enhancing monomers are required to be a balance of monomers promoting hard and soft segments of the resin.
