  • Adhesively securable multilayer relief plate for flexographic printing
    Patent number: 4871631
    Abstract: A flexographic printing relief-plate, which has a relief layer (P), an interlayer (Z) and a base layer (U), is provided with a double-sided adhesive sheet (W). The double-sided adhesive sheet (W) transmits actinic light and is firmly bonded to the base layer (U) on one side. On the opposing side, the adhesive sheet (W) has an adhesive force of from 1 to 6 N/25 mm. This force is less than the adhesive force on the side bonded to the base layer (U). The adhesive sheet (W) permits the flexographic relief printing plate to be repeatedly adhered to and removed from the printing cylinder without damaging the plate.
