Claim Text:
1. A method for producing an adhesive bond of two substrates, at least one of which is transparent and at least one of which has a surface with a surface energy of not more than 40 mN/m, comprising the use of a double-sided pressure-sensitive adhesive product comprising a pressure-sensitive adhesive layer having first and second pressure-sensitive adhesive surfaces, wherein the double-sided pressure-sensitive adhesive product is an adhesive transfer tape comprising no more than one pressure-sensitive adhesive layer and does not comprise a carrier material, the first pressure-sensitive adhesive surface being lined with a first release system, and the second pressure-sensitive adhesive surface being lined with a second release system, wherein the pressure-sensitive adhesive layer has a coatweight from 1 g/m the peel force of the first release system from the first pressure-sensitively adhesive surface, AZK the ratio of the bond strength of the fresh bond of the first pressure-sensitive adhesive surface to a surface having a surface energy of not more than 40 mN/m KK wherein AZK wherein the method comprises: (a) parting the first release system from the first pressure-sensitive adhesive surface, and contacting the first pressure-sensitive adhesive surface with the surface of the first of the two substrates to be adhered having a surface energy of not more than 40 mN/m; and (b) parting the second release system from the second pressure-sensitive adhesive surface and contacting the second pressure-sensitive adhesive surface with the surface of the second of the two substrates to be adhered, wherein the bond strength of the second pressure-sensitive adhesive layer to the surface of the second of the two substrates is less than 35 mN/cm.
