Abstract: The present disclosure relates to an adhesive printing form attachment layer comprising a support, and a permanently sticky layer suitable for receiving a printing form and fixing a printing form during a printing operation provided on the support, wherein the permanently sticky layer comprises a crosslinked silicone-based material. The present disclosure further relates to a method for preparing an adhesive printing form attachment layer, as well as a printing cylinder comprising it, the use of the an adhesive printing form attachment layer for fixing a flexographic printing plate during a printing operation on a printing cylinder, and a method of operating a printing machine wherein the adhesive printing form attachment layer is used.

Abstract: The present invention relates to an adhesive printing form attachment layer comprising a support, and a permanently sticky layer suitable for receiving a printing form and fixing a printing form during a printing operation provided on the support, wherein the permanently sticky layer comprises a crosslinked structure obtained by crosslinking a crosslinkable composition comprising at least one polyurethane-based polymeric compound that has two or more crosslinkable groups, which are preferably ethylenically unsaturated groups, and two or more —NHC(O)O— linkages. A method of preparing the adhesive printing form attachment layer and of operating a printing machine using the adhesive printing form attachment layer are also disclosed.

Abstract: A pressure-sensitive adhesive comprising at least 60 wt % of a polymer blend, where the polymer blend consists of a first polymer component A, a second polymer component B, and optionally one or more further polymer components (C, D, . . . ), where the first polymer component A is present at not less than x wt % in the polymer blend, where 90?x?99, and where the second polymer component B and any further polymer components C, D, . . . present are present in total at y wt % in the polymer blend, where y=100?x, where each polymer component (A, B, C, . . . ) derives to an extent of at least 60 wt % from (meth)acrylic monomers, wherein none of the polymer components (A, B, C, . . . ) is homogeneously miscible at room temperature with any of the other polymer components (A, B, C, . . . ), and so a multi-phase system is present.

Abstract: The invention relates to the use of an adhesive tape to adhesively bond printing plates, during which the impairment of the adhesive bonds by air bubble inclusions between the adhesive tape and a substrate should be reduced. This is achieved by using an adhesive tape comprising at least one adhesive layer, wherein the adhesive layer has at least one groove that does not extend to one of the edges of the adhesive layer, and the portion of the entire groove volume of the adhesive layer that is associated with such grooves is more than 50%.

Abstract: The aim of the invention is to improve an impairment to the adherence of an adhesive tape to a substrate caused by the inclusion of air bubbles between the adhesive tape and the substrate. According to the invention, said aim is achieved by means of an adhesive tape which comprises at least one adhesive layer, wherein the adhesive layer has at least one groove and none of the grooves extends as far as one of the lateral edges of the adhesive layer. The invention further relates to a release liner having a surface which has at least one ridge, wherein none of the ridges extends as far as one of the lateral edges of the release liner.
