The present invention provides an adhesive composition for a touch sensor comprising: a photopolymerizable compound; a titanocene-based compound as a photoinitiator; and an acid functional group-containing polyfunctional acrylic compound as a curing accelerator. The adhesive composition for a touch sensor according to the present invention can exhibit corrosion resistance to a touch sensor while directly attaching a touch sensor on a UV-impermeable substrate, and thereby it can be effectively used for attaching a touch sensor on various substrates.

An anti-plasma adhesive tape utilized for manufacturing a semiconductor package includes a substrate; and an adhesive layer formed on the substrate, wherein the adhesive layer is selected from a group composed of acrylic adhesive, light-curable resin and photoinitiator. The anti-plasma adhesive tape is attached to a backside of a lead frame of the semiconductor package before a plasma-cleaning process and removed from the lead frame after a molding process. After the anti-plasma adhesive tape is cured by irradiating an energy ray and removed from the lead frame, there is no residual adhesive left on a molding compound of the semiconductor package.
