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 mono-functional meth(acrylic) monomer A whose homo-polymer or co-polymer exhibit a glass transition temperature (Tg) between 40° C. and 140° C., (b) at least one monofunctional meth(acrylic) monomer B of the following structure (B): 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-H3 or O-[(CH2)2-O]<custom-character file="US20050004304A1-20050106-P00900.TIF" wi="20" he="20" id="custom-character-00001"/>s; 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.
