A releasable pressure sensitive adhesive composition comprising: (a) a block copolymer comprising at least one poly(monovinyl aromatic hydrocarbon) block and at least one poly(conjugated diene) block and having a vinyl content of at least 3% by weight, (b) a tackifying resin, and (c) a plasticizer, wherein the block copolymer has been cross-linked through its vinyl groups by means of a reaction with an organohydrogenpolysiloxane crosslinking agent containing at least two hydrogen atoms being directly bonded to a silicon atom in the presence of a crosslinking catalyst and wherein the plasticizer is present in an amount of from 1 to 50 parts by weight per 100 parts by weight of block copolymer. The releasable adhesive composition can be suitably applied in removable self-adhering memo notes and in removable tapes and labels.
