Claim Text:
1. A self-adhesive article comprising a support layer coated with an adhesive layer, said support layer having an elongation at break ranging from 50 to 1200% and a bulk density ranging from 25 to 1200 kg/m 3 , said adhesive layer being obtained by cross-linking an adhesive composition comprising: a) a mixture of at least two polymers having at least 20% of dialkoxylated silyl functions, with respect to the total quantity of silyl functions in the mixture of polymers, and comprising: and in formulae (I), (II), (III), and (IV) above: B represents one of the two formulae:  where D and T represent a hydrocarbon radical comprising 2 to 66 carbon atoms, linear, branched, cyclic, alicyclic or aromatic, saturated or unsaturated, optionally comprising one or more heteroatoms, R R R R R n is an integer such that the average molar mass of the polyether block of formula —[OR m is an integer such that the average molar mass of the polymer ranges from 600 g/mol to 100000 g/mol, p is an integer equal to 0, 1 or 2, f is an integer equal to 2 or 3; b) at least one tackifier resin, and c) at least one cross-linking catalyst.
