ADHESIVE COMPOSITION FOR ADHERING PRINTING PLATES TO IMPRESSION CYLINDERS FOR FLEXOGRAPHIC PRINTING

摘要

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 CH2═C(R1)(COOR2), where R1=H and R2 is 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 CH2═C(R3)(COOR4), where R3=H or CH3 and R4 is a linear alky radical with at least 12 C atoms, (d) acrylic acid and/or methacrylic acid.

1. 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),whereR1=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/orR1=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),whereR3=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.
