Production method of photosensitive flexo printing material, and flexo printing edition for newspaper

摘要

This invention, at least to be development possible with the metal make backing of flexibiility and are administered to this gluing layer and the organic medium which, itself at least the elastomer type binder of 1 kinds, ethylene characteristic unsaturated monomer, the optical initiator or the optical initiator composition and include the plasticizer Mitusige affinity layer and the transparent base course which and, in accordance with necessary includes with the exfoliation possible protective film to produce the flexo printing edition of the newspaper which being the photosensitive flexo printing material in order, entire thickness of the flexo printing material to be 300 - 1000 millimicrons, the elastomer type binder the mass average molecular weight of 80000 - 150000g/molIt possesses the shiyoa A hardness of Mw and 50 - 80, the quantity of the plasticizer 5 - 50 mass % in the chemical ray the image way it exposes the photosensitive flexo printing material, and the flexo printing material which feature that it is the range vis-a-vis the quantity of all the constitution amounts of Mitusige affinity layer, develops, and it regards the production method of flexo printing edition of the newspaper due to drying with 105 - the 160C.
