Claim 12:
13. A self-adhesive article comprising an adhesive layer consisting of a crosslinked adhesive composition comprising:
E) at least one polysilylated polymer having a number-average molar mass (Mn) of at least 20000 g/mol, wherein the at least one polysilylated polymer comprises a polyether and/or polyurethane main chain and at least two hydrolysable silylated end groups, said silylated end groups being attached to the main chain of the polymer by a urethane or ether function (referred to as a connector group),
F) a tackifying resin mixture comprising at least one type (i) and (ii) tackifying resin, wherein each resin has a hydroxyl number less than or equal to 50 and wherein type (i) and type (ii) tackifying resins are defined as follows:
i. one or more resins selected from the group consisting of PICCO AR-100, PICCO AR-85, NORSOLENE M1090, and PICCO A-10; and
ii. one or more resins selected from the group consisting of NORSOLENE W110 and NOROSLENE W85; and

G) at least one crosslinking catalyst,
H) excluding any monosilylated polymer.
