PRESSURE-SENSITIVE ADHESIVE MASS FOR LOW-ENERGY OR ROUGH SURFACES

摘要

The invention particularly relates to pressure sensitive adhesive materials. According to at least one embodiment, the pressure sensitive adhesive material comprises at least partially crosslinked polyacrylate based on a 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. Include. The monomer mixture comprises a) 5 to 100 wt% of the formula CR ³₂ = C(R ² )(COOR ¹ ) as monomer A (where R ¹ is a branch of 16 to 22 C atoms with at least 2 branch points Is an alkyl group, R ² is selected from H, methyl or halogen, and R ³ are each independently selected from H or halogen) acrylic acid ester, b) 0 to 20 wt% of the formula CR ⁵₂ = C(R ⁴ )(COOH) (wherein R ⁴ is selected from H, methyl or halogen, and R ⁵ are each independently selected from H or halogen) of acrylic acid, c) 0 to 30 wt% of monomer C As an olefinically unsaturated monomer having at least one functional group as, the monomer C is a monomer not belonging to the monomers A, B and D, and d) 0 to 95 wt% of the formula CR ⁸₂ = C(R ⁷ ) as monomer D COOR ⁶ ) acrylic acid ester (wherein R ⁶ is a linear, single branched, cyclic or polycyclic alkyl group having 1 to 14 C atoms, R ⁷ is selected from H, methyl or halogen, R ⁸ Each independently of each other is selected from H or halogen).
