Abstract: PURPOSE:To prevent the generation of cracks by incorporating a quinonediazide compd. and pulverized particles respectively having specified conditions into a photosensitive resin layer. CONSTITUTION:The photosensitive resin layer contains 100pts.wt. quinonediazide compd. and 10-150pts.wt. pulverized particles of which the average particle size is below the film thickness of the photosensitive resin layer and has the grain size distribution contg.

Abstract: PURPOSE:To provide a thermoplastic resin compsn. Which is highly flexible and in which thermal degradation resistance, chemical resistance, weathering resistance, antistatic properties, etc. are improved, by a method wherein a specified amount of a polyether ester is blended with an ABS resin. CONSTITUTION:(A) 50-95pts.wt. of a rubber-reinforced resin contg. a polymer consisting mainly of a conjugated diolefin as a rubber component and a polymer consisting of an arom. vinyl and acrylonitrile, or the arom. vinyl, acrylonitrile and a methacrylic ester as a resin component, is melt-mixed with (B) 5-50pts.wt. of a polyether ester to obtain the desired compsn. The polyether ester is a copolymer consisting of a polyether glycol or a copolyether glycol, and is produced from an arom. dicarboxylic acid, an alkyl dicarboxylic acid or a cycloalkyl dicarboxylic acid and an alkylene glycol or a cycloalkylene glycol.

Abstract: PURPOSE:To enable relief of small relief angles and deep spot and dropout depth by using a polyester film containing an ultraviolet light absorber. CONSTITUTION:The ultraviolet light absorber haveing the chemical structure formula of preferably the formula (R is alkyl) 0.001 to 5wt%, preferably 0.1 to 4wt% is added prior to the polymerization process or melt extrusion of the copolymer in which more than 85% of repetitive units are ethylene terephthalate or ethylene-2, 6-naphthalate units or the polyester mixed with 15wt% or under of other polymers. This polyester is formed to an unoriented film of more than 0.50 in intrinsic viscosity measured preferably at 25 deg.C in O-chlorophenol by a melt extrusion process, following to which this film is biaxially oriented. This film has satisfactory transparency and permits application of various surface treatments.

Abstract: PURPOSE:To make a high-viscosity ink, a quick-drying ink or solvent serviceable without occurrence of clogging in printing to enable a continuous printing of fine characters and images with a sharp printing quality, by a method wherein a brush for scraping an ink remaining in the recessed portions of a plate surface is disposed close to a rotating plate cylinder. CONSTITUTION:A brush 8 for scraping an ink remaining the recessed portions of a plate surface is disposed close to a plate cylinder 6. Even after a plate surface 7 comes into contact with an elastic rubber 9 of a transfer cylinder, an ink remaining in cells is scraped by the brush 8. This brush 8 is so provided that it can approach to or separate from the plate surface and the tip end of the brush is pressed into the cells. The material of brush 8 for use is not particularly limited, but generally a bristle of a natural fiber, such as animal hair and hemp-palm, or a synthetic fiber, such as polypropylene, polyamide, and polyester, is especially preferable because of its resistance to solvent and appropriate rigidity. A material with a fiber diameter of the order of 10mum-1mm is preferable, and particularly that of 50-500mum is desirable.

Abstract: PURPOSE:To increase a difference between an exposed part and unexposed part with the adhesive power between laminated layers and the developing soln. resistance of a photosensitive layer by successively providing the photosensitive layer contg. a quinonediazide compd. and silicone rubber layer on a base and subjecting the laminate to image exposing then to a heating treatment thereby developing the same. CONSTITUTION:The laminate for image formation is provided with the photosensitive layer contg. the quinonediazide compd. lined on the base and the silicone rubber layer thereon. The laminate is then exposed with an active light source and is subjected to a heat treatment in succession thereof. The heat treatment temp. is 100-200 deg.C. The solubility of the photosensitive layer between the exposed part and unexposed part or the effect of increasing the difference in the adhesiveness between the photosensitive layer and the silicone rubber layer is deteriorated at =200 deg.C. The silicone rubber layer of the exposed part is independently removed or removed together with the photosensitive layer by brushing the printing surface of the printing plate subjected to the heat treatment by a developing pad contg. a developing soln., by which the surface of the photosensitive layer or the substrate surface is exposed.

Abstract: PURPOSE:To prevent printing plate performance from being lowered with time, by sequentially providing a photosensitive resin layer and a silicone rubber layer in lamination on a specified base. CONSTITUTION:The base on which the photosensitive resin layer and the silicone rubber layer are sequentially provided is provided with a covering layer on a rubber elastic body, which covering layer comprises a rubber component and is resistant to solvents. The rubber component in the covering layer may be, for example, a natural rubber or a synthetic rubber (polybutadiene rubber, nitrile rubber, urethane rubber, a polyamide elastomer or the like), which is used singly or in combination of two or more, and is used in the state of being mixed or cross-linked with a thermosetting polymer binder. The most preferable covering layer is one comprising the same rubber component as that in the rubber elastic body, in which case the adhesion of the layer to the rubber elastic body is enhanced. In addition, when the covering layer comprising the rubber component and the polymer binder cross-linked with each other is used, solvent resistance is enhanced, and the range of application of developing liquids at the time of forming the printing plate is widened.
