The pressure-sensitive adhesive tape made of a flat, support material (8) provided with pressure-sensitive material (7, 9) on two sides is coated on at least one side of the support material with a polymer based pressure-sensitive material which can be produced from a monomer mixture made of at least the following components: i.a) 49.5 89.5 wt % (in relation to the monomer mixture) acrylic acid ester and/or methyl acrylic acid ester or free acids thereof having the following formula: CH2=CH(R1)(COOR2), wherein R1 = H or CH3 and R2 is an alkyl radical having 1 - 10 C-atoms or H and the homopolymer has a static glass transition temperature of < -30 DEG C; i.b) 10 - 40 wt % (in relation to the monomer mixture) acrylic acid ester and/or methyl acrylic acid ester having the following formula: CH2=CH(R3)(COOR4), wherein R3 = H or CH3 and R4 is a cyclic alkyl radical with at least 8 C atoms or a linear alkyl radical having at least 12 C atoms and the homopolymer has a static glass transition temperature of at least 30 DEG C; i.c) 0.5 10 wt. % (in relation to the monomer mixture ) acrylic acid ester and/or methyl acrylic acid ester having the following formula: CH2=CH(R3)(COOR5), wherein R3 = H or CH3 and R5 = H or an aliphatic radical with a functional group X, wherein X = COOH, OH, -NH, NH2, SH, SO3H and the homopolymer has a static glass transition temperature of at least 30 DEG C. |
