The present invention relates in particular to pressure sensitive adhesive materials. According to at least one embodiment, the pressure sensitive adhesive material comprises at least partially crosslinked polyacrylate based on monomer mixture and at least one tackifying resin present in a fraction of 20 to 60 parts by weight per 100 parts by weight of polyacrylate . The monomer mixture a) 5 to the formula as a monomer A of 100 wt% CR 3 2 = C (R 2) (COOR 1) ( where, R 1 is at least two branches of 16 to 22 C atoms having a single branch point alkyl group, and, R 2 is H, is selected from methyl or halogen, R 3 are each together an acrylate ester of a independently is H or selected) halogen, b) 0 to 20 wt% of the formula CR as monomer b 5 2 = C) from 0 to 30 wt.% Of a monomer C (R 4 ) (COOH), wherein R 4 is selected from H, methyl or halogen and R 5 is each independently of the other H or halogen; c) (D) from 0 to 95% by weight of monomer D, of a compound of the formula CR 8 2 = C (R 7 ) (where R 1 is a monovalent organic group having at least one functional group, in the acrylic acid ester (where the COOR 6), R 6 is from 1 to 14 C atoms with Type, a single branched, cyclic or polycyclic alkyl group, R 7 is selected from H, methyl or halogen, and R 8 comprises independently, it is H or selected from the halogen). |
