ABSTRACT:
An intaglio ink composition and method of using the same for printing by the intaglio process are disclosed. The composition comprises a pigment, a vehicle composed basically of a resin and solvent, and a small amount, e.g., 0.005 to 0.5 wt.%, of an antioxidant composition consisting of a mixture of phenolic and amine antioxidants. The antioxidant composition serves to reduce the tendency of gravure ink formulations to streak during the printing process. A preferred gravure ink formulation contains a small amount of an antioxidant composition consisting of a mixture of 2,6-di-tert-butyl-4-methylphenol and 4,4'-bis(1,1,3,3-tetramethylbutylphenyl)amine.
