<p>Reactive silica particles capable of producing coatings exhibiting excellent scratch resistance, weather resistance, adhesiveness, and curability, while satisfying a wide spectrum of performances from transparency to semi-transparency and providing a glossy surface as well as a frosty surface. Reactive silica particles comprises silica particles and an organic compound chemically bonded to the silica particles via a silyloxy group, wherein the organiccompound has a polymerizable unsaturated group, a group represented by formula (1) (wherein X is a group selected from -NH-, -O-, and -S- and Y is a group selected from oxygen and sulfur, provided that when X is -O-, Y is a sulfur atom), and a group represented by formula (2) (wherein Z is a group selected from oxygen and sulfur).</p> |
