  • Method of processing lithographic printing plate precursors
    Patent number: 6649319
    Abstract: A method of processing imageable elements useful as alkaline-developable lithographic printing plate precursors that does not require either a rinsing step or a further gumming step is disclosed. The method comprises simultaneously developing and gumming the imaged element with an aqueous alkaline developing-gumming solution comprising one or more water-soluble polyhydroxy compounds of the following structure: R1(CHOH)nR2 in which n is 4 to 7; and either (i) R1 is hydrogen, aryl, or CH2OH; and R2 is hydrogen, alkyl group having 1 to 4 carbon atoms, CH2OR3 in which R3 is hydrogen or an alkyl group having 1 to 4 carbon atoms, CH2N(R4R5) in which R4 and R5 are each independently hydrogen or an alkyl group having 1 to 4 carbon atoms, or CO2H, or (ii) R1 and R2 together form a carbon—carbon single bond.
