Abstract
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 organic compound has a polymerizable unsaturated group, a group represented by the following formula (1), ##STR1## (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 the following formula (2), ##STR2## (wherein Z is a group selected from oxygen and sulfur)
