    Abstract: PURPOSE: To obtain good solubility and homogeneity in a normal alkali developer soln. by forming an intermediate layer comprising a specified vinylalcohol polymer having a specified compsn. which is modified to be soluble or dispersible with water or an aq. soln. CONSTITUTION: This photoresist film consists of a carrier film, an intermediate layer formed on the carrier film, and a photosensitive layer and a coating film formed on the intermediate layer. The intermediate layer consists of a vinylalcohol polymer which is modified to the soluble or dispersible in water or an aq. soln. and contains 5 to 75wt.%, preferably 10 to 60wt.% of [-O-CH2 - CH2 -]x -units chemically bonded in the polymer molecule. In formula, x is at least 4. Thereby, the intermediate layer has enough adhesion strength with a material which is generally used as a carrier film and causes no difference in the adhesion strength between to the photosensitive layer and to the carrier film. Thus, good solubility and chemical homogeneity in a normal alkali developer soln. can be obtd. without forming a gel.

    Abstract: PURPOSE: To improve the adhesiveness of a relief layer to a carrier material and to shorten the exposure time when the printing plate is produced by incorporating a specified partially polymerized aryl glycidyl ether (meta)acrylate or using an intermediate layer formed there form. CONSTITUTION: An intermediate layer is deposited on a carrier, and further a photosensitive relief forming layer formed from the mixture of a polymer binder, photopplymerizable ethylenic unsaturated compd., photopolymerization initiator and thermopolymerization initiator is deposited. At least a partially polymerized compd. shown by formula I is further incorporated. In the formula, R is hydrogen or alkyls having 1-10 carbon atoms, R is hydrogen or methyl, X is -C2 H2 -, -(CH4 -CH2 -O)n -C2 H4 -, -(CHCH3 -CH2 O)n -CHCH3 -CH2 , etc., and (n) is 1 to 8. As a result the adhesiveness of the relief layer is remarkably improved, and the exposure time is drastically shortened when the printing plate is produced.

    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).
