Abstract: front page image
(EN)A surface treatment composition includes a solution having a pH within a range of above 4 to 8 that includes metal cations produced in situ from a metal-containing substance having a Ksp no greater than 1x10-6 in a reaction with an acid having a pKa in a range of -3.0 to +3.5. The composition further includes an agent mixed with the solution that is either a surface sizing agent or a coating agent used on a paper substrate. A print media includes the composition applied to a paper substrate. Preparation of the composition includes reacting the metal-containing substance with the acid, adjusting the pH to above 4 to 8, and mixing the metal cation-containing solution with either the surface sizing or coating agents.
(FR)L'invention concerne une composition de traitement de surface qui comprend une solution, ayant un pH se situant dans la plage au-dessus de 4 jusqu'à 8, qui comprend des cations métalliques obtenus in situ d'une substance contenant du métal ayant une Ksp non supérieure à 1x10-6 dans une réaction avec un acide ayant un pKa se situant dans la plage de -3,0 à +3,5. La composition comprend en outre un agent mélangé avec la solution qui est soit un agent de collage en surface, soit un agent de revêtement utilisé sur un substrat en papier. Un support d'impression comprend la composition appliquée à un substrat en papier. La préparation de la composition comprend la réaction de la substance contenant un métal avec l'acide, l'ajustement du pH au-dessus de 4 jusqu'à 8 et le mélange de la solution contenant un cation métallique avec soit l'agent de collage en surface, soit l'agent de revêtement.
