Pressure-sensitive adhesives and methods, for bonding flexible printing plates, comprising at least one adhesive component comprising at least one polymer component based on a monomer mixture comprising at least one of the following monomers: at least one acrylic ester; at least one methacrylic ester; acrylic acid; and methacrylic acid. The pressure-sensitive adhesives further comprise 1 to 30 wt %, based on the overall blend of the at least one adhesive component without solvent, of a polyvinyl acetate.

Pressure-sensitive adhesives for bonding flexible printing plates

A pressure-sensitive adhesive comprising at least one adhesive component comprising at least one polymer component based on a monomer mixture comprising at least one of the following monomers:

The invention relates to a repulpable adhesive comprising orthophosphoric acid, to adhesive tapes comprising at least one layer of such an adhesive, and to the use of adhesive tapes of this kind.

Repulpable adhesives

Pressure-sensitive adhesive composition, having at least one polymer component formed of a monomer mixture of at least (a) one acrylic ester and/or methacrylic ester of the formula CH&#x2550;C(R)(COOR), where R&#x2550;H and Ris a linear alkyl radical with 2 to 10 C atoms or a branched alkyl radical with at least 4 C atoms, (b) at least one N-alkyl substituted acrylamide, (c) at least one acrylic ester and/or methacrylic ester of the formula CH&#x2550;C(R)(COOR), where R&#x2550;H or CHand Ris a linear alky radical with at least 12 C atoms, (d) acrylic acid and/or methacrylic acid.

Adhesive composition for adhering printing plates to impression cylinders for flexographic printing

Composition for preparing a crosslinked pressure-sensitive adhesive, comprising a pressure-sensitive adhesive comprising a polymer component based on one or more monomers having at least one ethylenically unsaturated bond and for which the glass transition temperatures Tof the corresponding homopolymers are at least 0&#xb0; C., some of the monomers having at least one ethylenically unsaturated bond also having at least one carboxyl group, acrylic esters and/or methacrylic esters which are each selected such that the glass transition temperatures Tof the corresponding homopolymers are not more than &#x2212;20&#xb0; C., at least one resin component having a softening point of at least 100&#xb0; C., and at least one difunctional or polyfunctional crosslinker.

Pressure-sensitive adhesive tapes for bonding printing plates

Use of a double-sided adhesive tape for fastening silicone rubbers, the adhesive tape having a backing and two layers of adhesive, the first layer of adhesive being composed of an acrylate-based pressure-sensitive adhesive and the second pressure-sensitive adhesive being composed of a crosslinked pressure-sensitive silicone adhesive.
