A photo-curable adhesive composition for a display panel assembly comprising: a) at least one polyurethane acrylate having a Tg value of from -70 to 20 캜; b) one or more (meth) acrylate monomers; c) at least one chain transfer agent; d) two or more thixotropic agents, wherein the first thixotropic agent is selected from the group consisting of hydrophobic fumed silica, hydrophilic fumed silica and mixtures thereof, the second thixotropic agent is selected from the group consisting of modified ureas, polyhydroxycarboxylic acid esters, Mixtures thereof; e) at least one photoinitiator; f) one or more plasticizers; And g) one or more defoaming agents. The photo-curable adhesive composition can be used to bond two transparent substrates together, or to bond one transparent substrate and one opaque substrate together. In addition, the composition may be used in a method of making an optical assembly. |
