MULTILAYER SHEET MATERIAL IN THE FORM OF A PRINTING BLANKET OR OF A PRINTING PLATE
The invention relates to a multilayer sheet material 10 in the form of a printing blanket or of a printing plate, in particular for the printing of conical or cylindrical vessels made of, for example, plastic, styropore, paperboard, metal, etc., with a multiple-ply printing layer 1,2 made of at least one polymeric material and at least one other layer 3, 4, where the individual layers form, with one another, an adhesive bond that is not amenable to non-destructive separation.
The upper ply 1 of the printing layer, which during the printing procedure faces toward the object to be printed, comprises from 40 to 80 phr of butadiene rubber (BR) and from 20 to 60 phr of butyl rubber (IIR), and the lower ply 2, which during the printing procedure faces away from the object to be printed, comprises from 80 to 100 phr of butyl rubber (IIR).
