Fingerprint-erasing cured film, method for manufacturing same, display and touch panel using same, and electronic device using these

Abstract

Fingerprint-erasing cured films for rendering fingerprint depositions on various surfaces quickly less visible, or invisible; a manufacturing method therefor; a display or touch panel using the same; and electronic devices using these are provided. A liquid coating film including a solvent and a polymerizable resin composition curable by an activating energy beam is formed. In a state of the solvent being included within the film, the film is cured to form a cured film containing the solvent, preferably using a release material whose surface has undergone matte processing; and the solvent is evaporated in a subsequent drying step, whereby a cured film with a multitude of micropores on the surface is formed. Fingerprint soiling is rendered not readily visible or invisible. By using the cured film, there are obtained displays, touch panels, and electronic devices having fingerprint-erasability. To improve fingerprint-erasability, adding a water-absorbent compound to the film composition is preferable.
