摘要：
A non-dye containing flexographic ink containing a polymer or copolymer of a 3,4-dialkoxythiophene in which the two alkoxy groups may be the same or different or together represent an optionally substituted oxy-alkylene-oxy bridge, a polyanion and a latex binder in a solvent or aqueous medium, characterized in that the polymer or copolymer of a 3,4-dialkoxythiophene is present in a concentration of at least 0.1% by weight in the ink and that the ink is capable of producing a colorimetrically additive transparent print; a method of preparing the flexographic ink; and a flexographic printing process therewith.
