    Patent number: 6387594
    Abstract: A plate making film has a layer provided on a transparent substrate, the layer consisting essentially of a polymeric compound composed of a repeating unit represented by the following general formula (1): &Brketopenst;AXAR1&Brketclosest;  (1) where A is x, y and z each denote an integer of 1 or more, X is a residue of an organic compound having 2 active hydrogen groups, Y is a hydrocarbon group having 1 or more carbon atoms, and R1 is a dicarboxylic acid compound residue, or a diisocyanate compound residue. On the plate making film, an image is formed, preferably, by ink jets using, preferably, a plate making ink containing a mono- or disazo dye which is a yellow dye highly ultraviolet absorbing properties for a wavelength of 350 to 450 nm. An inexpensive, high resolution, high grade photomask for plate making is produced thereby.
