Abstract
An ink composition suitable for ink jet printing is made from a fatty acid ester base and a diluent, wherein the base consists essentially of a fatty acid which is liquid at room temperature, a polyalkylene glycol, and a dye which has been reacted with the fatty acid to form an ester. The base is combined with a compatible diluent, such as an alcohol having a low-viscosity and low vapor pressure, to provide an ink composition especially suited for ink jet dot printing of high-definition symbols such as bar codes. The ink of the invention resists spreading on rough surfaces, and thus can be used to print bar codes directly on the sides of paperboard cartons.
