Abstract[English]
The present invention relates to a method for etching at least one surface of a sulfur-containing thermoplastic resin-substrate, the method comprising the steps (A) to (C), wherein step (C) is an etching step including a contacting with a liquid etching composition. The liquid etching composition comprises (a) a mineral acid selected from the group consisting of sulfuric acid and nitric acid, and (b) a dialkyl sulfoxide and/or a phenyl-comprising sulfoxide.[French]
La présente invention concerne un procédé de gravure d'au moins une surface d'un substrat en résine thermoplastique contenant du soufre, le procédé comprenant les étapes (A) à (C), l'étape (C) étant une étape de gravure comprenant une mise en contact avec une composition de gravure liquide. La composition de gravure liquide comprend (a) un acide minéral choisi dans le groupe constitué par l'acide sulfurique et l'acide nitrique, et (b) un sulfoxyde de dialkyle et/ou un sulfoxyde comprenant du phényle.
