Hot-melt pressure-sensitive adhesive (HMPSA) composition, comprises: at least one of styrene block copolymers (25-50%) e.g. polystyrene-polybutadiene-polystyrene; at least one of compatible tackifying resins (35-75%), which are liquid or have softening temperature below 150[deg] C; and supramolecular polymers (1-20%), obtained by reaction between: 1-(2-aminoethyl)-2-imidazolidone and fatty acid composition comprising dimers and/or trimers of identical or different fatty acids and/or identical or different fatty acids (51-100%); and monomers of identical or different fatty acids (0-49%). Hot-melt pressure-sensitive adhesive (HMPSA) composition, comprises: at least one of styrene block copolymers (25-50%) including polystyrene-polybutadiene-polystyrene, polystyrene-polyisoprene-polystyrene (SIS), polystyrene-polyisoprene-polybutadiene-polystyrene, polystyrene-poly(ethylenebutylene)-polystyrene or polystyrene-poly(ethylenepropylene)-polystyrene; at least one of compatible tackifying resins (35-75%), which are liquid or have a softening temperature below 150[deg] C; and at least one of supramolecular polymers (1-20%), obtained by reaction between 1-(2-aminoethyl)-2-imidazolidone (ureido diethylene triamine or UDETA) and a fatty acid composition comprising at least one of dimers and/or trimers of identical or different fatty acids and/or at least one of identical or different fatty acids (51-100%) and at least one of monomers of identical or different fatty acids (0-49%). Independent claims are also included for: (1) a multilayer system comprising an adhesive layer consisting of the HMPSA, a printable support layer adjacent to the adhesive layer, consisting of paper or a polymer film having at least one layer, and a protective layer adjacent to the adhesive layer; and (2) a self adhesive label obtained by converting the multilayer system. |
