The invention relates to a polymer (P) comprising at least one photoinitiator moiety (PI) and at least one dye moiety (DYE), wherein said at least one photoinitiator moiety (PI) and at least one dye moiety (DYE) are covalently linked to said polymer (P). Additionally, the invention relates to said polymer (P) being end-functionalized with optionally substituted acryloyi groups. The fact that both of these moieties are tightly bonded within the polymer, and the cross-linked polymer, means that the opportunities for leaching/migration of these components is reduced or even eliminated. Inks comprising at least one of said polymers are also provided. Methods for the manufacture of the polymers, and for printing are provided.
