Title
(EN) AQUEOUS DISPERSION OF RESIN PARTICLES
(FR) DISPERSION AQUEUSE DE PARTICULES DE RÉSINE
Abstract
(EN)
An aqueous dispersion of resin particles comprising a dispersing group covalently bonded to the resin and at least one repeating unit of formula I, II and/or III and which is obtainable by contacting a compound A comprising 2 functional groups selected from the group of functional groups -X-C(=0)-CHR1-C(=0)-R2, -X-C(=0)-C≡C-R2; or -X-C(=0)-CR1 =CR2-NR11 R12, wherein X, R1, R2, R3, R11 and R12 have the same meaning as that defined in the claims, with a compound B comprising at least two -NH2, -NH3+ or -N=C=0, with a crosslinking agent C. The invention also includes a method of producing the aqueous dispersion and further relates to an aqueous ink jet ink comprising the resin particles.
(FR)
L'invention concerne une dispersion aqueuse de particules de résine comprenant un groupe dispersant lié de manière covalente à la résine et au moins un motif répété de formule I, II et/ou III et qui peut être obtenue par la mise en contact d'un composé A comprenant 2 groupes fonctionnels choisis dans le groupe des groupes fonctionnels -X-C(=O)-CHR1-C(=O)-R2, -X-C(=O)-C≡C-R2 et -X-C(=O)-CR1=CR2-NR11R12, X, R1, R2, R3, R11 et R12 ayant la même signification que celle définie dans les revendications, avec un composé B comprenant au moins deux groupes -NH2, -NH3+ ou -N=C=O, avec un agent de réticulation C. L'invention concerne également un procédé de production de la dispersion aqueuse et concerne en outre une encre aqueuse pour jet d'encre comprenant les particules de résine.
