Abstract: A pressure-sensitive adhesive for bonding printing plates comprises one or more poly(meth)acrylates in a combined mass fraction of 50% or more and preparable by polymerization of a monomer composition comprising, based on the mass of the monomer composition: i) one or more first monomers selected from acrylic acid, methacrylic acid, dimethylacrylamide, hydroxybutyl acrylate, hydroxypropyl acrylate and hydroxyethyl acrylate in a combined mass fraction in the range from 10%-20%, and ii) one or more second monomers selected from (meth)acrylic esters of the formula (I), CH2═CR1—C(O)O—CHR2R3 (I), where R1 is hydrogen or methyl, where either i) R2 is hydrogen and R3 is a branched alkyl group having 16-20 carbon atoms, or ii) R2 is a linear or branched alkyl group having 3-10 carbon atoms and R3 a linear or branched alkyl group having 6-10 carbon atoms, in a combined mass fraction in the range from 20%-90%.
