"Fotossensu00ecvel flexographic printing element for the production of plates for flexographic printing of newspapers.Process for the production of flexographic printing plates for printing of newspapers, and flexographic printing plate for printing newspapers. The invention relates to a photosensitive printing element for the production of flexographic printing plates for printing newspapers, comprising at least a metal support flexible.An adhesive layer applied on the substrate, a layer of curing organically revealable, a layer of transparent substrate and, optionally, a removable protective sheet.When the total thickness of the flexographic printing element is from 300 to 1000 109 m, the elastomeric bonding agent has a molecular weight between weighted average 80000 to 150.000 g / mol and a shore a hardness between 50 to 80, in which the amount of softening agent ranges from 5 to 50 percent by weight in relation to the quantity of all the components of the curing layer.The invention also relates to a method for the production of flexographic printing plates by means of press exposure in the form of image of the flexographic printing element to actinic light.Revelation and drying at 105 C 160 198 198.
