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

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

• ia) 50 to 89.5 wt % of at least one acrylic ester and/or methacrylic ester having the following formula:
• CH2═C(R1)(COOR2),
• where
• R1=H and R2 is a linear alkyl radical having 2 to 10 C atoms or a branched, noncyclic alkyl radical having at least 4 C atoms and/or
• R1=CH3 and R2 is a linear alkyl radical having 8 to 10 C atoms or a branched, noncyclic alkyl radical having at least 10 C atoms,
• ib) 5 to 20 wt % of at least one N-alkyl-substituted acrylamide,
• ic) 5 to 25 wt % of at least one acrylic ester and/or methacrylic ester having the following formula:
• CH2═C(R3)(COOR4),
• where
• R3=H or CH3 and R4 is a linear alkyl radical having at least 12 C atoms,
• id) 0.5 to 5 wt % of acrylic acid and/or methacrylic acid,
• the amounts figures being based in each case on the monomer mixture.
