Abstract: A method for improving the adhesiveness of the surface of a synthetic polymeric substrate to coatings, which comprises coating the surface of the synthetic polymeric substrate with a photopolymerizable composition comprising (A) a hydrophilic resin obtained by the polymerization of a polymerizable unsaturated monomer composition containing at least 10% by weight of a hydrophilic unsaturated monomer, (B) a radical-polymerizable mono-unsaturated monomer and (C) a triplet state sensitizer having a triplet state energy of at least 50 Kcal/mole, and then irradiating actinic rays to the coated surface of the polymeric substrate.

Abstract: A photocurable composition comprising a major part of a polymerizable compound with at least two ethylenically unsaturated bonds in one molecule thereof, and minor parts of a photosensitizer and a nitrosodiarylamine compound is described. The nitrosodiarylamine compound serves to suppress thermal polymerization of the photocurable composition. The photocurable composition is especially suitable for use in making paints and printing plate materials.

Abstract: A transparent image forming sheet and method for forming transparent images on the sheet, in which the sheet comprises a transparent film base, an opaque conductor layer being formed on one side of the transparent film base and a semiconductive layer containing powder of metallic oxide semiconductor, a mixture of non-conductive metallic compound and conductive substance, or polymeric semiconductor, and the method comprises the steps of applying electric voltage between the semiconductive layer and the conductor layer through recording stylus and development using corrosive liquid and/or dissolving solvent.The transparent image sheet can be used for several optical purposes including the preparation of a printing plate for photographs without the screen process.
