Abstract
A coating composition having excellent anti-static properties and suitable for use as anti-static hard coating films. The coating composition comprises a radical polymerizable binder and a salt based on an anion including a cage-shaped frame. The anti-static hard coating film formed using the coating composition has excellent anti-static properties, abrasion resistance and moist heat resistance. Such film may be used for an optical laminate a display device, and the like.
Claims15
A coating composition comprising:
