Title
(EN) AQUEOUS COATING COMPOSITION AND A POLYOL FOR SUCH A COMPOSITION
(FR) COMPOSITION AQUEUSE DE REVETEMENT, ET POLYOL Y RELATIF
Abstract
(EN)
Aqueous coating composition, for example for use as a clear or pigmented top coat or a primer, comprising: a) a polyol or a mixture of polyols having: i) a content of carboxylate- and/or carboxylic acid-functional groups C and ii) a content of sulfonate- and/or sulfonic acid-functional groups S, the total content C + S being between 0,09 and 0,6 mmol/gram polyol and the ratio C/S having a value between 0,5 to 20; b) one or more cross-linkers, such as a polyisocyanate. More than 50 % of the sulfonic acid groups and the carboxylic acid groups are neutralized with amines. Polyol having a content C of carboxylate- and/or carboxylic acid-functional groups and a content S of sulfonate- and/or sulfonic acid-functional groups, the total content C + S being between 0,09 and 0,6 mmol/gram polyol, and the ratio C/S having a value between 0,5 to 20. Process for preparing a polyol resin, comprising the following steps: polymerizing a mixture of hydroxy-functional, olefinically unsaturated monomers without acid-functional groups and without carboxylate- or sulfonate-functional groups in a solvent-borne solution to obtain a hydrophobic polyol; adding to the mixture, after a portion of the monomer mixture has polymerized, a mixture of said monomers with olefinically unsaturated monomers having hxdroxy groups, carboxylic acid and/or carboxylate groups and/or sulfonic acid and/or sulfonate groups to obtain a hydrophilic polyol; evaporating the solvent; dispersing the polyol in a mixture of water and amines.

L'invention concerne une composition de revêtement aqueuse destinée à être utilisée, par exemple, comme couche de finition transparente ou pigmentée ou comme amorce, laquelle composition comprend: a) un polyol ou un mélange de polyols renfermant: i) une teneur C de groupes fonctionnels carboxylate- et/ou acide carboxylique et ii) une teneur S de groupes fonctionnels sulfonate et/ou acide sulfonique, la teneur totale C + S étant comprise entre 0,09 et 0,6 mmol/gram de polyol et le rapport C/S ayant une valeur comprise entre 0,5 et 20; b) un ou plusieurs agents de réticulation, notamment un polyisocyanate. Plus de 50 % des groupes acide sulfonique et des groupes acide carboxylique sont neutralisés par des amines. L'invention concerne également un polyol caractérisé par une teneur C de groupes fonctionnels carboxylate- et/ou acide carboxylique et par une teneur S de groupes fonctionnels sulfonate- et/ou acide sulfonique, la teneur totale C + S étant comprise entre 0,09 and 0,6 mmol/gram polyol de polyol, et le rapport C/S ayant une valeur comprise entre 0,5 et 20. L'invention concerne enfin un procédé de préparation d'une résine de polyol, consistant: à polymériser un mélange de monomères oléfiniquement insaturés à fonction hydroxy exempt de groupes fonctionnels acides et de groupes fonctionnels carboxylate- ou sulfonate- dans une solution support de solvants en vue d'obtenir un polyol hydrophobe; à ajouter au mélange, après polymérisation d'une partie du mélange de monomères, un mélange desdits monomères avec des monomères oléfiniquement insaturés présentant des groupes hydroxy, acide carboxylique et/ou carboxylate et/ou acide sulfonique et/ou sulfonate de manière à obtenir un polyol hydrophobe; à faire évaporer le solvant; et à disperser le polyol dans un mélange renfermant de l'eau et des amines.
