Title (EN) A METHOD AND LIQUID COMPOSITION FOR THE PRODUCTION OF INDELIBLE SCRIPT ON A PAPER SUBSTRATE
(FR) PROCEDE ET COMPOSITION LIQUIDE PERMETTANT LA FORMATION SUR UN SUBSTRAT EN PAPIER D'UNE ECRITURE INEFFAÇABLE
Abstract: front page image
(EN)A method for the production of indelible script on a paper substrate provides for the introduction of at least one highly penetrating colouring compound having at least two reactive functional groups into the substrate in a vehicle as well as its subsequent polymerisation in situ in the substrate itself. To advantage to colouring compound is selected from oxidation dyes and its in situ polymerisation is achieved by oxidation.
(FR)Procédé permettant la formation sur un substrat en papier d'une écriture ineffaçable. Il consiste à introduire dans le substrat au moins un composé colorant fortement pénétrant possédant au moins deux groupes fonctionnels réactifs et étant compris dans un véhicule, puis à le polymériser $i(in situ) dans le substrat lui-même. Le composé colorant est avantageusement sélectionné parmi les colorants d'oxydation, et sa polymérisation $i(in situ) s'effectue par oxydation.
