A resin composition to prevent damage to a surface of a substrate from an etchant when an edge thereof is strengthened, the resin composition comprising:
- a resin mixture of 20˜50% by weight which includes a phenol resin and a epoxy acrylate resin with a weight ratio of 10:90 to 90:10, and a solvent.
A method for manufacturing a touch device, the method comprising:
- forming a protective layer per touch sensor on first and second surfaces of a mother substrate on which two or more touch sensors are formed;
- dividing the mother substrate into two or more substrates of the touch sensor unit by mechanically cutting or chemically treating the mother substrate;
- chemically strengthening an edge of each of the divided substrates;
- and
- removing the protective layer from at least one divided substrate.
