Title (EN) METHOD FOR COATING A PLURALITY OF FLUID LAYERS ONTO A SUBSTRATE
(FR) PROCEDE D'APPLICATION D'UNE PLURALITE DE COUCHES DE FLUIDES SUR UN SUBSTRAT
Abstract:
(EN) A method for minimizing coating defects caused by strikethrough when simultaneously slide coating a first fluid layer (80), a second fluid layer (82), and a third fluid layer (84). The method includes preparing the first, second, and third fluids (55, 60 and 66) such that the first solute is incompatible with the second and third solutes and such that the fist fluid minimizes strikethrough of at least one of the second and third fluids to a slide surface when the first fluid is positioned between the slide surface (53) and the second and third fluids. The present invention is useful in preparing imaging, data storage, and other media.
(FR) L'invention porte sur un procédé de réduction des défauts d'application de revêtement, ces derniers étant provoqués par les traversées de couches dans le cas d'application simultanée par transfert en continu d'une première couche de fluide (80), d'une deuxième couche de fluide (82) et d'une troisième couche de fluide (84). Ce procédé consiste à préparer les premier, deuxième et troisième fluides (55, 60 et 66) de sorte que le premier soluté soit incompatible avec les deuxième et troisième solutés et que le premier fluide réduise les traversées de couches d'au moins un de ces deuxième et troisième fluides sur un plan de transfert en continu lorsque le premier fluide se trouve entre le plan de transfert en continu (53) et les deuxième et troisième fluides. La présente invention est utile dans la préparation de supports utilisés pour l'imagerie, le stockage de données ou autres utilisations.
