  • Hard coating composition and resin product with hard coat
    Patent number: 6852368
    Abstract: A resin substrate having a hard coat formed from a hard coat composition which comprises colloidal silica, a silicon compound having a fluoroalkyl group and optionally an ultraviolet light absorbing organic group. This resin substrate can retain water-repellency even when it is used in the open air and prevent the adhesion of a stain while it keeps its abrasion resistance for a long time by the hard coat composition.
