Pressure-sensitive adhesives for bonding printing plates

摘要

Crosslinked pressure-sensitive adhesive comprising at least one base polymer component obtainable by free-radical copolymerization of the following monomers:
a) linear acrylic esters having 2 to 10 C atoms in the alkyl radical,b) branched, non-cyclic acrylic esters having a glass transition temperature Tg (based on the DSC measurement to DIN 53765) of not more than −20° C.,c) 8% to 15% by weight of acrylic acid,d) optionally up to 10% by weight of further copolymerizable monomers,

characterized in that the ratio of the linear acrylic esters to the branched acrylic esters is in the range from 1:6 to 10:1 mass fractions.

1. Crosslinked pressure-sensitive adhesive comprising at least one polymer component obtained by free-radical copolymerization of the following monomers exclusively:
a) linear acrylic esters having 2 to 10 C atoms in the alkyl radical, b) branched, non-cyclic acrylic esters having a glass transition temperature Tg, of not more than −20° C., and c) acrylic acid, in an amount of at least 11% up to 13% by weight, based on the total weight of monomers, wherein the mass ratio of the linear acrylic esters to the branched acrylic esters is in the range from 1:6 to 10:1.
