20080206492 | Double-Sided Pressure-Sensitive Adhesive Tapes For the Production of Lc Displays With Light-Reflecting and Light-Absorbing Properties - A pressure-sensitive adhesive tape, in particular for producing a bond between optical liquid crystal data displays (LCDs), comprising an upper and a lower side with light-reflecting properties on the upper side and light-absorbing properties on the lower side and further comprising a support film with an upper and a lower side, each side of the pressure-sensitive adhesive tape having an outer pressure-sensitive layer, and said adhesive tape being characterized in that at least one metallic reflective layer for the reflection of light is provided between the outer pressure-sensitive layers of at least one pressure-sensitive adhesive layer, colored black, for the absorption of light and in that at least the outer pressure-sensitive layer on the upper side is transparent. | 08-28-2008 |
20080206491 | Double-Sided Pressure-Sensitive Adhesive Tape For Producing Lc Displays With Light-Reflecting and Light-Absorbing Properties - A pressure-sensitive adhesive (PSA) tape, particular for producing or bonding optical liquid-crystal data displays, having two PSA layers (b, b′) and at least one carrier sheet (a), wherein the PSA tape has light-reflecting properties on both its top and bottom faces and at the same time is light-absorbing at least in so far as light not reflected is unable to penetrate the adhesive tape. The PSA tape is implemented in particular in such a way that at least between one face of the carrier sheet and the PSA layer located on that face there is a white paint layer (c). As a preference, a metallic layer (d) is provided between the carrier sheet and the white paint layer. | 08-28-2008 |
20080202682 | Heat-Activatedly Bonding 2D Element - The invention provides a substantially two-dimensional element (2D element) which bonds adhesively without bubbles under heat activation and has at least one heat-activable adhesive, one side face of said element having a groove element. The groove element comprises at least one groove adapted for the transport of a fluid. The groove is set into the side face of the 2D element in such a way that it is open towards the side face. It runs continuously from one edge section of the side face to a further edge section of the side face. By way of the groove structure formed from the at least one groove, liquid or gaseous fluids which form or collect in the bond area can be drained from the plane of the bond, thereby improving the strength of the bond. The invention further offers methods of producing and employing this 2D element. | 08-28-2008 |
