    Abstract: PURPOSE: To make it possible to produce an endless printing plate body with which an ink holding characteristic and an ink transfer characteristic are made easily reproducibly adjustable as desired by image forming exposure and development of an endless photosensitive recording layer suitable for production of the endless printing plate body by providing a method which is as simple as possible and is usable in multiple applications for the purpose of forming the endless recording layer described above. CONSTITUTION: Specified surface patterns are imparted by a roller treatment to the photosensitive polymer endless recording layer during the time of curing of the recording layer, thereby, the purposes are achieved in a known method for forming the endless solid recording layer of a photosensitive polymer on a cylindrical surface for production of the endless printing plate body by endlessly forming the layer of the photosensitive polymer recording material for forming the recording layer on the cylindrical surface in a fluid state and curing the layer thereon.

    Abstract: PURPOSE: To provide a photosensitive recording element with which copying is executed simply by uniformly exposing the image mask on a recording layer to chemical rays prior to development. CONSTITUTION: This recording element sensitive to UV band and visible band chemical rays has (A) a dimensionally stable substrate, (B) the negative processing photosensitive recording layer (B1) or the positive processing photosensitive recording layer (B2) and (C) the image mask which is directly placed on the surface of the photosensitive recording layer (B1) or (B2) and forms the relief-like patterns of the coating regions (C1) and non-coating regions (C2) substantially non-transmissible to the chemical rays to be used in either case. The relief-like patterns and the coating regions (C1) of the image mask (C) are composed of the liquid droplets or solid particles transferred onto the surface of the photosensitive recording layer (B1) or (B2).

    Abstract: PURPOSE: To improve adhesion property between a metal substrate for a printed circuit board and a layer transfer material by adding a specified adhesion improving agent. CONSTITUTION: This material consists of a film forming polymer as a binder, an org. compd. having two or more double bonds which enables addition polymn., a photopolymn. initiator (compsn.) and an adhesion improving agent (A), and if necessary, an assistant. The component (A) is a compd. expressed by the formula. In the formula, R', R" are preferably 1 to 4 C alkyl groups, M is preferably an alkali metal. As for the component (A), for example, sodium diethyl dithiocarbamate can be used. The obtd. material is applied on a polyester film to produce a photoresist film which can be used for the production of a printed circuit board.

    Abstract: PURPOSE: To ensure satisfactory stability in a rolled state even at the time of storage of a dry film resist over a long period of time by allowing a specified N-vinylamide copolymer or a polyamide additive to exist in a photopolymerizable recording layer. CONSTITUTION: The top of a carrier having dimensional stability is coated with a photopolymerizable recording layer developable with an aq. alkali soln. and contg. a polymer binder, at least one kind of ethylenic unsatd. photopolymerizable compd. and at least one kind of photoinitiator or further contg. other additives and/or auxiliaries. In the recording layer, an N-vinylamide homopolymer, an N-vinylamide copolymer contg. >=50mol% N-vinylamide units in a polymerized state or a polyamide additive having 1,500-300,000g/mol mol.wt. exists by 0.2-6wt.% of the total amt. of the recording layer. Laminating is facilitated and stability in a rolled state can be improved even at the time of storage of a dry film resist over a long period of time.

    Abstract: PURPOSE: To improve suitability to exposure by using a specified dye forming compsn. or further using a film forming polymer binder, a compd. having an ethylenic unsatd. double bond, a photopolymn. initiator activated by irradiation with chemical rays or its compsn., additives and auxiliaries. CONSTITUTION: This photosensitive compsn. contains a mixture of at least one kind of hexaarylbisimidazole compd. represented by formula I or its structural isomer with at least one kind of halogen-contg. compd. represented by formula II and at least one kind of dye forming compd. convertible into a dye by oxidation as a dye forming compsn. In the formula I, Ar is optionally substd. phenyl and Ar is phenyl or phenyl substd. by halogen or alkyl at the 2- or 2'-position. In the formula II, Hal is halogen and R is H, optionally substd. alkyl, cycloalkyl, aryl, heteroaryl or a heterocyclic group. This compsn. has satisfactory suitability to exposure, forms a very fine image faithful to the original and can guarantee sure reproduction.
