Abstract
1341010 Printing ink; treating tar ESSO RESEARCH & ENG CO 30 Dec 1971 [31 Dec 1970] 62048/70 Headings C4A and C5E A printing ink is based upon resinous compositions comprising a tar polymer produced from steam cracker tar or a fraction thereof and with a softening point in the range of 60‹ to 150‹ C., and a compatible solvent with a boiling point in the range 300‹ to 480‹ C. Steam cracker tar may be polymerized to produce the tar polymer by a catalytic or thermal process in which oxygen in the form of air is injected into the steam cracker tar which is continuously agitated. Suitable catalysts for the polymerization are aluminium chloride, strong inorganic acids such as hydrochloric or sulphuric acid, and heavy metal salts such as ferric, ferrous, cupric, and cuprous chloride. The tarpolymermayalternatively be a copolymer of steam cracker tar and formaldehyde produced in the presence of strong acid catalysts such as sulphuric acid or sulphonic acids. The copolymer may also include a third monomer such as phenol or a substituted phenol containing one or more alkyl groups with 1 to 20 carbon atoms. Other monomers which can be reacted with the tar or tar aldehyde copolymers are unsaturated dicarboxylic acids or anhydrides and esters thereof such as crotonic acid, phthallic acid, maleic acid and fumaric acid. The compatible solvent may be obtained by distillation of steam cracker tar to produce a higher liquid fraction. The solvent is aromatic and preferably naphthenic. Carbon black may be used as a pigment if required.
