Abstract: The adherence of the oleophilic polymer printing surface of a lithographic printing plate to the support of the lithographic printing plate is improved by an anchoring layer formed from a hydrophobic oleophilic ester colloid which is capable of being rendered hydrophilic by treatment with an aqueous alkali solution. After an image-wise exposure of the photosensitive layer of the presensitized photosensitive sheet used to prepare the lithographic printing plate and removal of the non-polymerized (non-image) portions of the photosensitive layer the plate is contacted with an aqueous alkali solution to render those portions of the anchoring layer, which have been exposed by removal of the non-polymerized portions of the photosensitive layer, hydrophilic. Accordingly, the portions of the anchoring layer underlying the oleophilic hardened polymeric printing surface remain hydrophobic oleophilic and therefore can increase the number of satisfactory printings which can be made from the lithographic printing plate.

Abstract: A lithographic printing plate system utilizing a composite plate having an aluminum printing member that can be recycled. An aluminum printing member has a light-sensitive coating thereon which forms the image area of the plate together with the aluminum member itself. A carrier plate supports the aluminum member. The carrier plate and the aluminum member are preferably releasably adhered together outside the image area of the plate, that is, along transverse and/or longitudinal edge positions adjacent the image area. The aluminum member is readily separated from the carrier plate for recycling after the printing run and the carrier plate can be reused or recycled.

Abstract: Compositions comprising the reaction product of a novel, highly branched polyalkylenimine-urea-aldehyde resin and a polyacrylic resin provide useful intermediate coatings when applied to preconditioned metal surfaces which may be subsequently coated with light sensitive materials to make photolithographic plates. The intermediate coating, particularly when applied to a grained or ungrained aluminum support member which has been anodized and finally coated with light sensitive materials produces a highly durable plate that possesses good storage characteristics and is capable of unusually extended press runs.

Abstract: 1,177,527. Photo-sensitive materials. GAF CORP. April 14, 1967 [April 15, 1966; July 5, 1966], No. 17346/67. Heading G3C. A photo-sensitive material comprises a metal support coated with an alkali-soluble intermediate layer consisting of a copolymer with 80-99% mole per cent of acrylate units and 1-20% of acrylic acid units, and with a layer containing a quinone diazide and a water-insoluble, alkali-resistant polymer. Specified polymers are polyvinyl acetate, polymethyl acrylate or methacrylate, cellulose ethers and esters and phenolmodified coumarone-indene resins. The support may be aluminium, copper, coated aluminium or chromium copper-aluminium. The material is imagewise exposed and developed with a polyhydric alcohol to remove the un-exposed areas to produce a negative printing plate; the copolymer layer being hydrophilic. If the developer contains an amine, the copolymer and light-sensitive layers are removed in the exposed areas and the bared metal surface etched to produce either a positive or a negative printing plate.
