ABSTRACT A color proofing foil of increased sensitivity to actinic light is provided which comprises a substantially transparent polymeric base sheet having a thin coating of a light sensitive composition on the surface of said sheet comprising a mixture of a colorant, a light sensitive material and an effective amount of anionic surfactant. The anionic surfactant is obtained by the reaction of P2O5 with a condensation product of an alkylene oxide and an organic compound containing a reactive hydrogen. The light sensitive coating compositions of this invention exhibit greatly increased exposure speed, while retaining the required good adhesion to film substrates, good scratch resistance, freedom from tack and acceptable resistance to over- development.
