Abstract: This invention relates to novel condensation products, novel light-sensitive condensation products of aromatic diazonium salts, processes for preparation thereof, and to light-sensitive reproduction materials, which latter comprise a support having a reproduction layer containing at least one of the novel light-sensitive products. The light-sensitive condensation products are prepared by first homo-condensing non-diazo containing monomers of the structure R--M--R to form an oligomer. The oligomer is next condensed with an aromatic diazonium salt form the desired novel light-sensitive condensation product. R is a reactive substituent capable of undergoing condensation reactions in acid medium. M is selected from the group consisting of aromatic hydrocarbons, diaryl ethers, diaryl sulfides, diaryl amines, diaryl sulfones, diaryl ketones and diaryl diketones. The resulting novel light-sensitive condensation products have approximately four times the speed of prior art compounds.

Abstract: Light sensitive coating compositions containing a dyestuff, which compositions exhibit improved adhesion to transparent film substrates, are disclosed. For example, the adhesion between a polyester base film and a light sensitive coating composition containing a light sensitive diazo material, a resinous binder and a dyestuff is improved by additionally incorporating into the composition an effective amount of an adhesion promoter based on a copolyester obtained by the esterification and subsequent polymerization of a lower alkylene glycol with a mixture of terephthalic acid, isophthalic acid, and at least one acyclic dicarboxylic acid. These coating compositions may be readily removed from the base film by appropriate lithographic developer solutions without substantial residual staining of the film by the dyestuff present in the coating composition.

Abstract: An electrophotographic apparatus for producing printing masters utilizing modulated laser light as the exposure source and a continuous process for producing such printing masters involving the steps of plate conveyance, synchronous charging and exposure, and electrostatic development and fusing of electrophotographic printing masters suitable for use in offset or lithographic printing processes. The apparatus comprises a transport system for sequentially conveying printing masters to the exposure platen which retains the masters in a fixed plane for synchronous charging and exposure, utilizing as a light source, a modulated laser beam. The optical and deflecting components of the exposure system are mounted in a moveable carriage member adapted to traverse a plane substantially parallel to the plane of the exposure platen such that the exposure laser will raster scan the platen area.

A test specimen in the form of a thin unnotched strand of known thickness is mounted in a holding means and subjected to impact by a pendulum type striking means having a predetermined potential energy content. The excess energy remaining in the striking means after breaking the specimen is measured and impact values determined by a mathematical formula as a function of specimen thickness and energy required to break the specimen.
