Abstract
Reactive particles have been invented that may be used for a curable composition exhibiting excellent cured product productivity and capable of forming coatings with high hardness, superior scratch resistance, excellent abrasion resistance, low curling properties, superb adhesion, and chemicals resistance, particularly high chemicals resistance, on the surface of various substrates; a curable composition containing the reactive particles; and cured products made from the curable composition.
