Adhesive bands for bonding printing plates

Composition comprises: (A) an adhesive mass comprising (A1) 60-90 wt.% of a polymer component based on (a) 5-25 wt.% of one or more compounds with at least an ethylenically unsaturated bond, where each monomer is selected in such a way that the glass transition temperature of the corresponding homopolymer is at least 0[deg] C, and a portion of the compounds further contains at least one carboxyl group, and (b) 75-95 wt.% of acrylic acid ester and/or methacrylic acid ester, and (A2) 10-40 wt.% of at least one resin component; and (B) at least one bi- or poly-functional crosslinking agent. Composition comprises: (A) an adhesive mass comprising (A1) 60-90 wt.% (based on the polymer component) of a polymer component based on (a) 5-25 wt.% of one or more compounds with at least an ethylenically unsaturated bond, where each monomer is selected in such a way that the glass transition temperature of the corresponding homopolymer is at least 0[deg] C, and a portion of the compounds with at least one ethylenically unsaturated bond further contains at least one carboxyl group, and (b) 75-95 wt.% (based on the polymer component) of acrylic acid ester and/or methacrylic acid ester, each of which is selected in such a way that the glass transition temperature of the corresponding homopolymer is not more than -20[deg] C, and (A2) 10-40 wt.% of at least one resin component with a softening point of at least 100[deg] C; and (B) at least one bi-or poly-functional crosslinking agent, where: the crosslinking agent is added such that the quantity ratio (V1) of the substance amount (n z) of the crosslinking active centers of the crosslinkers to the theoretical amount (n p) of the substance of the macromolecule of the polymer component (A1) is 1.5-2.5 (i.e. V1 = n z/n p= 1.5-2.5); the substance amount (n z) of the crosslinking active centers of the crosslinkers results from multiplying mass (m v) of the crosslinker that is divided by the molar mass (M v) of the crosslinkers with the number (f) of the crosslinking active centre per crosslinking molecule (i.e. n z= fx m v/M v); and the theoretical substance amount (n p) of the macromolecule of the polymer component (A1) results from the mass (m p) of the polymer components in the adhesive mass that is divided by the number average molar mass (M n) (i.e. n p= m p/M n). Independent claims are included for: (1) an adhesive mass obtained by crosslinking the composition; and (2) a double-sided adhesive band for bonding of flexible prin
