ている。Also, a method of manufacturing a relief plate using a photosensitive resin,
For example, a mixture of a linear polymer, a monomer having one or more photopolymerizable olefinic double bonds, and a photopolymerization initiator is formed into a sheet, irradiated with light through the original image, and the unexposed areas are treated with a solvent, etc. A method of washing and removing it to obtain a relief plate is known. In addition, a photosensitive layer containing an elastomeric polymer, such as chloroprene rubber (hereinafter referred to as CR), IJ rubber (hereinafter referred to as NBR), or polyurethane rubber, a photopolymerizable monomer, and a photopolymerization initiator, is further used. A method for producing reliefs for flexographic printing has also been proposed.

整する必要があり満足できるものとはいえない。(Problems to be solved by the invention) However, the conventional rubber plate for flexographic printing
It requires many steps to manufacture, which is extremely disadvantageous in terms of cost and time, and has the disadvantage that the obtained rubber plate itself has low precision. In addition, the relief produced by the method of producing a relief plate using a photosensitive resin has insufficient adhesion for flexographic printing on a substrate made of rough material or a substrate of uneven thickness. In addition, the hardness changes greatly depending on the temperature, and it is necessary to adjust the printing conditions depending on summer and winter, which is not satisfactory.
さらには耐印刷用インク性の劣るものもあり、印刷用イ

剤性の低下が著しいという問題点を有する。Furthermore, in the conventional relief plate for flexographic printing, that is, the system consisting of an elastomeric polymer monomer and a photopolymerization initiator, the elasticity of the main components CR and acrylic rubber decreases due to the polymerization and crosslinking reaction of the monomers. Furthermore, there was a problem in that the elasticity at low temperatures deteriorated significantly. Regarding this, it has been proposed to add plasticizers such as phthalate esters and phosphate esters, which are stabilizers for polyvinyl chloride, or to add liquid prepolymers with a molecular weight of 1,000 to 5,000. Since the liquid prepolymer does not participate in any way in photopolymerization, it has the problem of a significant decrease in solvent resistance.

In order to develop an excellent relief plate that can be used, the inventors have conducted extensive research, and by using a photosensitive rubber composition containing a completely new elastomeric component, they have achieved this objective, and the present invention has been achieved.
