Abstract:
An imageable element comprising:(A) a substrate; and (B) a radiation sensitive imageable composition applied on the substrate comprising: (a) a first layer, comprising: (i) a photosensitive composition which undergoes a decrease in solubility in a developer upon absorption of actinic radiation by the first layer, and (ii) an inhibitor which is activated by heat or radiation of longer wavelength than the actinic radiation to retard the decrease in solubility of the photosensitive composition of the first layer upon absorption of actinic radiation, wherein the inhibitor is a cyanine dye and is present in an amount equal to or greater than 1% by weight of the first layer, and (b) a second layer contiguous to the first layer comprising an ink repellent polymeric material which is transparent to both the actinic radiation and the longer wavelength radiation.
