Title (EN) METHOD AND LIQUID COMPOSITION FOR MARKING SUBSTRATES MADE OF PLASTICS MATERIAL
(FR) PROCEDE ET COMPOSITION LIQUIDE DESTINES AU MARQUAGE DE SUBSTRATS EN MATIERE PLASTIQUE
Abstract:
(EN) A method of forming a mark on a substrate made of plastics material comprises the step of applying a basic solution to a surface portion having a prefixed pattern of the substrate. In a preferred embodiment, the basic solution is used in combination with at least one alkali-stable water-soluble polymer, to produce a viscous liquid composition, which is advantageously applicable to the substrate by means of pad-printing and silk-screen printing processes.
(FR) Ce procédé de formation d'une marque sur un substrat en matière plastique comprend l'étape consistant à appliquer une solution basique sur une portion de surface du substrat, laquelle présente un motif préalablement fixé. Dans un mode de réalisation préféré, on utilise cette solution en combinaison avec au moins un polymère soluble dans l'eau et stable en milieu alcalin, afin d'obtenir une composition liquide visqueuse que l'on peut avantageusement appliquer sur le substrat à l'aide de procédés de tampographie et de sérigraphie.
