Abstract:
A method of producing a member comprising a predetermined pattern on a substrate, the method comprising: (a) providing a precursor comprising a substrate on which is provided a coating composition which includes a functionalized polymeric substance which is a phenolic resin having functional groups Q thereon wherein said functionalized polymeric substance is heat sensitive and said functional groups Q thereon cause said functionalized polymeric substance to have a reduced adhesive interaction with ink for use in waterless lithographic printing compared to the phenolic resin in the absence of said groups Q and (b) causing the pattern-wise application of heat to said coating composition and optional development thereby to define ink-accepting areas in heat exposed areas and non-ink-accepting areas in non-exposed areas, wherein the coating composition has a developer solubility which is not increased by incident UV or visible radiation.
