A method glues two plastic surfaces together via an adhesion produced by a heat-activatable adhesive. An adhesive, which is used as a heat-activatable adhesive, is based on i) at least one thermoplastic having a softening temperature or melting temperature in the region of between 90 and 120° C. At least one of the plastic surfaces that is to be glued is part of the substrate having a heat conductivity that is high enough to transfer the activation energy necessary for the adhesion of the heat-activatable adhesive

摘要:
The invention relates to an adhesive tape, especially for producing or gluing optical liquid crystal displays (LCDs). Said tape comprises a lower face and an upper face, the lower face having light-reflecting properties and the upper face having light-absorbing properties, a support film having an upper face and a lower face, said adhesive tape being provided on both sides with an adhesive layer. The inventive tape is characterized in that the support film has a content of antiblocking agents of less than 4000 ppm, the support film is brightly colored and at least one light-absorbing chromophoric layer is provided at least between the lower face of the support film and the adhesive layer disposed on said face.
