PROBLEM TO BE SOLVED: To provide an adhesive compositions usable in the manufacturing of an-adhesive article comprising a support of the PET type having satisfactory properties such as a high shear resistance and a high break temperature of the adhesive joint.SOLUTION: An adhesive article comprises a support layer coated with an adhesive layer, the support layer having an elongation at break ranging from 50 to 1200% and a bulk density ranging from 25 to 1200 kg/m3, the adhesive layer is obtained by cross-linking an adhesive composition comprising (a) to (c): (a) at least one polymer or a mixture of polymers having at least 20% of dialkoxylated silyl functions, with respect to the total quantity of silyl functions in the polymer or the mixture of polymers, and comprising at least 20% by weight of at least one polyurethane or at least one polyether comprising two or three hydrolyzable terminal groups of dialkoxysilane type and represented by formula (II); (b) at least one tackifier resin; and (c) at least one cross-linking catalyst. |
