  • Patent number: 11119597
    Abstract: Provided is a thin touch sensor having excellent flexibility and durability against bending. A thin adhesive layer with a high elastic modulus under the touch sensing electrode pattern serves as a substrate, and a thick adhesive layer with a low elastic modulus on top of the touch sensor layer disperses the stress of the optical film.

  • Patent number: 10428247
    Abstract: The present invention provides an adhesive composition for a touch sensor comprising: a photopolymerizable compound a titanocene-based compound as a photoinitiator; and a phosphoric acid-based compound or a phosphonic acid-based 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.
