[origin: WO9749664A1] A compound for use as a photoinitiator comprises a photoreactive portion and a pendent group, said photoreactive portion including an aromatic moiety and said pendent group incorporating at least one optionally-substituted poly(alkylene glycol) moiety. Preferred photoreactive portions include optionally-substituted benzophenone, thioxanthone and anthraquinone compounds substituted by a polyethylene glycol or polypropylene glycol moiety of average molecular weight in the range 150 to 900. Compounds of the type described are found to have low migration from cured films.
