The invention relates to an aqueous dispersion containing a pigment (B) that is at least partially sheathed in at least one radiation-curable polyurethane (A). Said radiation-curable polyurethane (A) is obtained by the reaction of (a) at least one di- or polyisocyanate, which on average contains between 1 and 10 allophanate groups and on average between 1 and 10 C-C double bonds per molecule with (b) at least one additional diisocyanate and (c) at least one compound comprising at least two groups that are capable of reacting with isocyanate.
L'invention concerne une dispersion aqueuse, contenant un pigment (B) recouvert au moins partiellement d'un polyuréthanne (A) durcissable par rayons, ledit polyuréthanne (A) durcissable par rayons pouvant être obtenu par transformation (a) d'au moins un polyisocyanate ou diisocyanate, qui contient entre 1 et 10 groupes d'allophanates et entre 1 et 10 doubles liaisons C-C par molécule, (b) au moins un diisocyanate supplémentaire et (c) au moins un composé comprenant au moins deux groupes destinés à la réaction avec un isocyanate.
