Abstract
A polymer complex is disclosed which is the reaction product of one or more polymers having a terminal or pendant hydroxyl group, or a terminal or pendent carboxyl group, or combinations thereof, with at least one metal complex and one alkyl phosphate. This polymer complex acts as an adhesion promotion agent as well as a viscosity stabilizer when formulated in a printing ink or coating.
