Abstract
A film touch sensor is prepared by performing a process in which a separation layer made of a specific component is formed on a carrier substrate, and an insulation film is formed on a transparent conductive film pattern, which is used as a planarization layer, an adhesive layer or a base layer.
Claims20
A film touch sensor comprising:
- a separation layer;
- an electrode pattern layer which is formed on the separation layer, and includes a sensing electrode and a pad electrode formed on one end of the sensing electrode;
- and
- an insulation layer formed on a top of the electrode pattern layer so as to cover a part or all of the electrode pattern layer,
- wherein the separation layer comprises a chain polymer including a side chain having an alcoholic secondary or tertiary hydroxyl group, and a cross-linking agent;
- and
- the side chain is made of a curable resin composition which has 3 to 30 carbon atoms, includes at least one saturated or unsaturated hydrocarbon group, or further includes at least one aromatic group, and has a bond selected from a group consisting of —COO—, —O—, and —CO— connecting the carbon atoms with each other.
