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.
本发明提供了一种感光性彩色打样制品,其中含有一种或多种抗光晕有效量的下表所示通式(I)的抗光晕染料:
其中Z是氧原子、NH或NR;R是1至12个碳原子的烷基或氢原子;R1代表1至12个碳原子的全氟烷基磺酰基或芳基磺酰基;R2代表1至12个碳原子的全氟烷基磺酰基、芳基磺酰基或氰基。式(I)的防光晕染料吸收波长范围约为 325 至 700 纳米的辐射,最好是约 325 至 450 纳米。
