Abstract: This invention is a method for preventing sticking of a resin plate surface by coating the solution of binder and photopolymerizable monomer on the surface of a photosensitive resin composed of binder, photopolymerizable monomer, and photopolymerization initiator, developing relief images by a photomechanical process, and then by drying the coating solution.

Abstract: The composition of this invention comprises:(a) a thermoplastic organic polymer,(b) a non-gaseous ethylenically unsaturated compound containing at least two terminal ethylenic groups capable of forming a polymer by photoinitiated addition polymerization,(c) an addition polymerization initiator activatable by actinic radiation, and(d) a benzotriazole carboxylic acid.

Abstract: The invention provides an improved method for the so-called dry-film process for forming a pattern-wise photoresist layer on the substrate surface in which a substrate is overlaid and laminated with a preformed film of a photosensitive composition called a dry film and photolithographically processed. In the inventive method, different from conventional dry-film processes, the substrate plate is first provided with a protecting layer of a photosensitive composition containing a halation inhibitor and the lamination with a dry film is performed without removing the protecting layer. After pattern-wise exposure to light, development of the photosensitive layer is undertaken by use of a developer solvent capable of dissolving both of the protecting layer and the pattern-forming layer. Despite the intervention of the protecting layer, the resolving power and image reproducibility are excellent.
