Abstract:
A printing plate precursor comprising a carrier, a radiation-sensitive printing layer and an overcoat, wherein the overcoat comprises:(a) at least one polymeric organic binder, soluble in water or in organic solvents having a water content of at least 50 wt.-% based on the total solvent content; and (b) at least one radiation-absorbing component wherein the absorption maximum with the longest wavelength of the radiation-absorbing component of the overcoat is at or below 550 nm, the radiation-absorbing component absorbs in the range on the long wavelength side of the maximum of the absorption band of the photoactive system of the printing plate precursor and the difference between the absorption maximum with the longest wavelength of the radiation-absorbing component of the overcoat and the absorption maximum with the longest wavelength of the radiation-sensitive layer of the printing plate precursor is in the range of 5 to 200 nm.
