Described is an adhesive composition with a high elasticity, measured in terms of elongation at break, and an elastic behavior approaching the ideal Hook law in the stress-strain diagram. Said adhesive composition comprises (a) at least one monofunctional meth(acrylic) monomer A whose homo-polymer or co-polymer exhibit a glass transition temperature (Tg) between 40 DEG C and 140 DEG C, (b) at least one monofunctional meth(acrylic) monomer B of the following structure (B): <CHEM> wherein R is H or CH3, R' is H or (CH2)nCH3, with n = 0 to 2, in particular CH2CH3 or H, and R" is C3-C20-alkyl or phenoxy or O-(CH2)n-CH3 or O-Ä(CH2)2-OÜn-CH2-CH3 with n = 0 to 2, in particular (CH2)nCH3 wherein n is 3 or 10 to 13 , and c) at least one liquid elastomer C in the molecular weight range of 1000 to 9000 with (meth)acrylic derivative groups, preferably (meth)acrylic ester groups, whereby the components A, B, and C are present in the following amounts: B based on the total weight of A+B+C = 5 to 20 % by weight, C based on the total weight of A+C = 30 to 70 % by weight. |
