Hot-melt pressure-sensitive adhesive (HMPSA) composition is disclosed comprising: a) 25 to 50% of a blend of SBS and SB styrene block copolymers; b) 45 to 75% of compatible tackifying resins having a softening temperature of between 80 to 150° C.; and c) 0.5 to 5.5% of fatty acids, the hydrocarbon chain of which comprises 10 to 22 carbon atoms.
