A pressure sensitive adhesive based on block copolymers which have at least one unit composed of a series of three alternating polymer blocks P(A) and P(B), whereinP(A) represents a homopolymer or copolymer block formed from a component A which itself comprises at least one acrylated macromonomer of general formulain which R<I>'=H or CH3 and R'' is an aliphatic linear, branched or cyclic, unsubstituted or substituted, saturated or unsaturated, alkyl radical having more than 30 carbon atoms, and the average molecular weight Mn of said at least one macromonomer being between 492 g/mol and 30 000 g/mol,P(B) represents a homopolymer or copolymer block formed from a monomeric component B which itself comprises at least one monomer B1, the polymer block P(B) having a softening temperature of from -80° C. to +20° C., and the polymer blocks P(A) being immiscible with the polymer blocks P(B).
