A polymeric photoinitiator, most suitably a polyurethane photoinitiator, is obtained by step-growth co-polymerization of at least one monomer (A) with at least one monomer (B). Monomer (A) includes a photoinitiator moiety, while monomer (B) is a monomer reactive with monomer (A) to form a polymer. A method produces the polymeric photoinitiator, a method cross-links the polymeric photoinitiator, and the polymeric photoinitiator is used as a photoinitiator of radical polymerization.
A polyacrylate is obtained by radical polymerization of at least one acrylate monomer (Ac) in the presence of a polymeric photoinitiator. The polymeric photoinitiator is a co-polymer of at least one photoinitiator monomer (A) with at least one monomer (B), and optional additional monomers (C). Rapid polymerization of the acrylate monomer is provided. A method produces a polyacrylate using the polymeric photoinitiator as described, and a polymeric photoinitiator is used as the photoinitiator of radical polymerization of acrylate monomers.

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.
