Title (EN) ELECTROCOAGULATION PRINTING INK AND ITS USE
(FR) ENCRE D'IMPRIMERIE ELECTROCOAGULANTE ET SON UTILISATION
Abstract: front page image
(EN)An improved electrocoagulation printing ink comprising acetylene glycol-based surfactant, an electrocoagulable polymer, a coloring agent, a soluble electrolyte and a liquid medium. The printing ink is capable of being removed with ease from the surface of a positive cylindrical electrode in continuous printing and free from the occurrence of a unfavorable spot-like stain in the part having no images of a printed matter. A printed matter which is free from the lowering of quality by a spot-like stain in an unprinted part thereof, and an electrocoagulation printing method for providing such a printed matter are also disclosed.
(FR)La présente invention concerne un type amélioré d'encre d'imprimerie électrocoagulante. Elle comprend un tensioactif à base d'acétylène-glycol, un polymère électrocoagulable, un colorant, un électrolyte soluble et un milieu liquide. Cette encre d'imprimerie, qui se nettoie facilement de la surface d'une anode cylindrique d'impression en continu, ne produit pas de taches en micropoints sur les parties laissées vierges des imprimés. L'invention concerne également, d'une part un imprimé dont la qualité n'est pas dégradée par la formation de taches en micropoints dans les zones non imprimées, et un procédé d'impression par électrocoagulation permettant la production d'un tel imprimé.
