The present invention provides a photosensitive color proofing article incorporating an antihalation effective amount of one or more antihalation dyes of the general formula (I) shown below:
wherein: Z is an oxygen atom, NH, or NR; R is an alkyl group of 1 to 12 carbon atoms or a hydrogen atom; R1 represents a perfluoroalkylsulfonyl group of 1 to 12 carbon atoms or an arylsulfonyl group; and R2 represents a perfluoroalkylsulfonyl group of from 1 to 12 carbon atoms; an arylsulfonyl group; or a cyano group. The antihalation dyes of formula (I) absorb radiation within the wavelength range of from about 325 to 700 nm and preferably, from about 325 to 450 nm.
