Abstract
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 at least 2 functional groups selected from the group of functional groups —X—C(═O)—CHR1-C(═O)—R2, —X—C(═O)—C≡C—R2; or —X—C(═O)—CR1═CR2-NR11R12, with a compound B comprising at least two —NH2, —NH3+ or —N═C═O, wherein X, R1, R2, R3, R11 and R12 have the same meaning as that defined in the claims and wherein compound A and/or B comprise a dispersing group. The invention also includes a method of producing the aqueous dispersion and further relates to an aqueous inkjet ink comprising the resin particles.
