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.
