    摘要: 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.

    摘要: A new liquid cleaner composition is provided for the mild and gentle removal of polymeric materials from sufaces without leaving any residues. The said new cleaner composition is an emulsion of the water-in-oil type comprising an aqueous phase finely dispersed in a continuous phase selected from the group consisting of nonflammable, fire-retardant, high-boiling, and fire-retardant and high-boiling organic phases, the volume ratio of the finely dispersed aqueous phase to the continuous organic phase being in the range of from 90:10 to 10:90. The new liquid cleaner composition can contain alcohols, surface-active agents and further useful additives. The new liquid cleaner composition is most preferably used in the process for preparing photopolymerized flexographic relief printing plates as the developer for washing out the non-irradiated and thus non-photopolymerized areas of the imagewise irradiated relief-forming recording layers of the said flexographic relief printing plates.
