Abstract: Parent patent discloses prepn. of a radiation-hardenable unsatd. polyester binder from (A) polyhydric alcohol, (B) plain alpha,beta-olefinically unsatd. dicarboxylic acid and/or a polycarboxylic acid which is free from polymerisable aliphatic multiple bonds and (C) acrylic cpd. which can be condensed in. (A), (B) and, (D) a norbornane deriv. contg. >=1 functionally identical COOH, OH or amino gp. are reacted together. The prod. is then reacted with (C). In this Patent of addn. N-1-4C-alkylol-acrylamide or -methacrylamide is used as (C). The binders are pref. used as printing ink components, esp. insolvent-free printing inks. Binders admixed with fillers can be used as mastics. Binders have high storage stability and high hardening velocity on irradiation with UV light.

The prod. is then reacted with (C). In this Patent of Addn. a hydroxy-1-3C alkyl-acrylate or -methacrylate is used as (C). The binders are pref. used in printing ink compsns. esp for solvent-free printing inks, or when admixed with fillers they can be used as mastics. They have high storage-stability, e.g. can be stored 6 months without gelling, thickening and changes in viscosity. Hardening rate can be >400 m/min. on irradiation with UV light.

Abstract: Writing ink contains a triphenyl methane dyestuff in aq. acid soln. together with an aromatic sulphonic acid and/or an aromatic hydroxycarboxylic acid. The (blue) ink is completely storage-stable and requires no preservatives. The colour strength and brilliance is also improved. Specifically the ink contains in aq. soln. 0.5-2%, esp. 1% dyestuff which is pref. in its easily sol. ammonium salt form; and 0.1-2% of the aromatic acid and opt. an inorganic acid to obtain the desired optimum pH of 1.5-3, esp. 2-2.5.
