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.
Claims28
An ink or coating composition containing an adhesion promoting agent comprising the reaction product of:
- one or more polyamides having
- a) a terminal or pendent carboxyl group, or a terminal or pendent hydroxyl group;
- or
- b) a combination of a terminal or pendent carboxyl group and a terminal or pendent hydroxyl group;
- with at least one metal orthoester and at least one alkyl phosphate;
- wherein the reaction product is present in an amount of 2 wt % to 5 wt %, based on the total weight of the composition.
A method of improving the adhesion performance of an ink or coating composition comprising adding to said composition an agent comprising the reaction product of one or more polyamides having a terminal or pendent carboxyl group, or a terminal or pendent hydroxyl group, or a combination of a terminal or pendent carboxyl group and a terminal or pendent hydroxyl group, and at least one metal orthoester and at least one alkyl phosphate;
- wherein the reaction product is present in an amount of 2 wt % to 5 wt %, based on the total weight of the composition.
