Abstract
A coating composition comprising a silicone resin having at least two types of fluorinated organic substituent groups and hydroxyl or monovalent hydrolyzable groups forms, through brief curing at low temperature, a uniform transparent coating having a low refractive index (e.g., below 1.42) and a high hardness as well as excellent water repellency, oil repellency, and antifouling property. Stacking the coating on a high refractive index layer results in an antireflection article having an improved reflectance.
