Abstract
Abstract A releasable adhesive composition in the form of a paste and having improved adhesive and release properties comprising: (i) 10 to 80% (preferably 15 to 30%) by weight of a styrene-based block copolymer, preferably a styrene-olefin-styrene block copolymer; (ii) 10 to 80% (preferably 10 to 30%) by weight of a naphthenic or, preferably, paraffinic plasticiser, and optionally also an aromatic plasticiser; and (iii) 10 to 80% (preferably from 20 to 75%) by weight of an aliphatic, cycloaliphatic or aromatic (chloro)hydrocarbon solvent:
