Abstract
An aqueous dispersion containing a polyamide and non-polyamide polymer is prepared by dissolving the polyamide in an organic solvent with a surfactant to form a polyamide solution. Water is then added to the polyamide solution to form an aqueous dispersion. The non-polyamide polymer can be added before or after the addition of water. The polyamide/non-polyamide dispersion can be used to produce an ink with better adhesion to plastic substrates and reduced blocking problems.
