Abstract

The security ink disclosed uses a siccative vegetable oil such as linseed oil as both liquid and binder. The pigments/dyes used are soluble in oil, and have a particle size of less than 50 millimicrons, preferably in the range of from 10 to 30 millimicrons. The security ink acts in the manner of a dye and penetrates into, and the pigments/dye particles adhere to, the fiber structure of the paper. A two-tone product is also disclosed.
