Beschreibung
Zusammenfassung:	The invention relates to water-based coating compositions comprising A) at least one water-dilutable polyurethane hybrid binder, obtained by polymerization of at least one polyurethane macromonomer, containing at least one lateral and/or terminal vinyl group, in the presence of at least one unsaturated monomer copolymerizable with the polyurethane macromonomer, B) optionally at least one curing agent, and C) at least one pigment, characterized in that, the at least one polyurethane macromonomer is based on at least one polyhydroxyl compound, said polyhydroxyl compound comprises at least 50 % by weight of at least one polycarbonate polyol, which is liquid at 20C, the % by weight are based on the total amount of the polyhydroxyl compound. L'invention concerne des compositions de revêtement à base d'eau comprenant A) au moins un liant hybride de polyuréthane diluable à l'eau, obtenu par polymérisation d'au moins un macromonomère de polyuréthane, contenant au moins un groupe vinylique latéral et/ou terminal, en présence d'au moins un monomère insaturé copolymérisable avec le macromonomère de polyuréthane, B) éventuellement au moins un agent de durcissement et C) au moins un pigment. Selon l'invention, ledit au moins un macromonomère de polyuréthane est à base d'au moins un composé polyhydroxyle, ledit composé polyhydroxyle comprenant au moins 50 % en poids d'au moins un polycarbonate-polyol, qui est liquide à 20°C, les % en poids étant basés sur la quantité totale du composé polyhydroxyle.
