    摘要: Laser-engravable flexographic printing elements including a thermally crosslinked, elastomeric, laser-engravable relief-forming layer E are made by producing a multilayer composite which has at least a two-layer composite formed of a depot layer D and an uncrosslinked precursor layer V for the relief-forming layer E which is directly adjacent to the depot layer D. Optionally, the multilayer composite may include further layers, such as support foils or films and/or protective films. The precursor layer V most preferably includes at least one elastomeric binder, and at least one ethylenically unsaturated monomer and, optionally an absorber for laser radiation and/or further additives. The depot layer D most preferably includes at least one elastomeric binder, and at least one thermally decomposing polymerization initiator and, optionally, an absorber for laser radiation and/or further additives. The thermally decomposing polymerization initiators are allowed to diffuse out of the depot layer D into the precursor layer V. If desired the depot layer D may be removed. Thermal crosslinking of the precursor layer V thereby yields the crosslinked elastomeric, laser-engravable, relief-forming layer E.

    摘要: A punch rivet and a die for the production of a punch rivet connection are described. The punch rivet is characterized by special rivet foot and underhead geometries. In the region of the rivet foot, the shank outer face and shank inner face are connected by means of a small radially outer radius and a larger radially inner radius, which radii merge into one another tangentially. The angle that the common tangent encloses with a radial plane is in the range of 10°±20°. The die is preferably matched to the described punch rivet, but can also be used in combination with conventional punch rivets.
