Abstract

An environmentally safe additive and vehicle system are provided for water-based and oil-based printing inks, paints, coatings and adhesives which can be rapidly transferred, dispersed, dispensed, spread, dried and cured. The low cost, stable additive and vehicle system enhance multiple color, high speed printing with sharp, highly defined images and superior quality, and can be used on many different types of substrates, such as paper, paperboard, cardboard, clay coated board, foil, plastic, glass, metal, wood and composites. The additive may be formed by the reaction product of a photoinitiator, such as an UV-activated polyelectrolyte, and a monomer, such as an acrylate or a methacrylate in an aqueous solution. In other embodiments, the additive is formed from a carboxylic acid or anhydride and alkylalkanolamine monomer or a dialkylaminoalkyl acrylate or methacrylate monomer in an aqueous solution.
