    Abstract: There is described a method of forming a lithographic plate by the heat-mode imaging method which comprises coating on a base which can be used as a lithographic base, a positive working photosensitive composition which comprises a naphthoquinone diazide ester of a phenolic resin or a naphthoquinone diazide ester and a phenolic resin and at least one substance which absorbs infrared radiation, overall exposing the assembly to ultraviolet light to render the photosensitive composition developable, imaging the plate by means of a laser which emits in the infrared region of the spectrum and then developing the plate to remove those areas of the photosensitive composition not exposed to the laser.

    Abstract: There is described coated on a lithographic base a complex of a developer-insoluble phenolic resin and a compound which forms a thermally frangible complex with the phenolic resin. This complex is less soluble in the developer solution than the uncomplexed phenolic resin. However when this complex is imagewise heated the complex breaks down so allowing the non-complexed phenolic resin to the dissolved in the developing solution. Thus the solubility differential between the heated areas of the phenolic resin and the unheated areas is increased when the phenolic resin is complexed. Preferably a laser-radiation absorbing material is also present on the lithographic base. A large number of compounds which form a thermally frangible complex with the phenolic resin have been located. Examples of such compounds are quinolinium compounds, benzothiazolium compounds, pyridinium compounds and imidazoline compounds.

    Abstract: There is described a lithographic plate which comprises a base coated with a photopolymerisable composition which comprises a polymeric binder, at least one free-radically polymerisable ethylenically unsaturated compound and as the photoinitiator combination a metallocene compound, N-phenyl glycine or a substituted N-phenyl glycine or an N-phenyl glycine derivative together with a third component which is a substance which helps in the reaction initiation but also increases the sensitivity of the photopolymerisable composition to a desired region of the spectrum.
