A fluid set for inkjet printing comprising a fluid comprising a compound functionalized with at least two functional groups being of a primary amine or a secondary amine, and an aqueous inkjet ink comprising a colorant and a polymeric particle comprising an oligomer or polymer having at least 3 repeating units comprising a functional group according to general formula I, II or III. The fluid is preferably a pre-treatment liquid or over coat liquid.

Fluid set for inkjet printing

An aqueous inkjet ink comprises a compound functionalized with at least two functional groups selected from the group consisting of a primary amine and a secondary amine, a colorant and a polymeric particle comprising an oligomer or polymer having at least 3 repeating units comprising a functional group according to general formula I, II or III general formula I general formula II general formula III

Aqueous resin based inkjet ink

An aqueous dispersion of particles comprising a resin having at least one repeating unit of formula I, II and/or III and which is obtainable by contacting in a liquid comprising water, 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, the functional groups are linked by a linking group comprising a polyester, polyether, polyolefin, polydimethylsiloxane or polycarbonate chain with a compound B comprising at least two —NH, —NHor —N═C═O, wherein X, R1, R2, R3, R11 and R12 have the same meaning as that defined in the claims and w. The invention also includes a method of producing the aqueous dispersion.

Aqueous dispersion of capsules

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(═O)—CHR1-C(═O)—R2, —X—C(═O)—C≡C—R2; or —X—C(═O)—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 —NH, —NHor —N═C═O, 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.

Aqueous dispersion of resin particles

A negative-working lithographic printing plate precursor includes a coating including vinylogous vitrimer particles. The vinylogous vitrimer particles include a resin having at least one moiety of formula (I), (II), and/or (III): 

Lithographic printing plate precursor

A heat-sensitive imaging element includes an IR dye, and more particularly a heat-sensitive lithographic printing plate precursor includes the IR dye. A method for making the lithographic printing plate produces a print-out image of high contrast upon exposure to IR-radiation or heating.

Heat-sensitive imaging element

A heat-sensitive imaging element includes an IR dye having a structure according to Formula I, wherein at least one of the Rgroups is a group which is transformed by a chemical reaction, induced by exposure to IR-radiation or heat, into a group which is a stronger electron-donor than the R; or wherein at least one of the Rgroups is a group which is transformed by a chemical reaction, induced by exposure to IR-radiation or heat, into a group which is a stronger electron-acceptor than the R. The imaging element is able to form a visible print-out image with a high contrast directly after image-wise exposure by IR-radiation or heating.
