<p>The objective of the present invention is to provide a curable composition containing an organosilicon excellent in stability, being excellent in curability, and leading a cured material excellent in scratch resistance and adherence to a base material, and a production method of an organosilicon compound which is hardly gelated during or after the production thereof and is excellent in stability as well as solubility to an organic solvent and radical curability. The present curable composition comprises an organosilicon compound produced by hydrolysis copolycondensation of (A) a silicon compound R 0 Si(R 1 ) n X 1 3-n [wherein R 0 represents a (meth)acryloyl group; and X 1 represents a hydrolyzable group] and (B) a silicon compound SiY 1 4 [wherein Y 1 represents a siloxane-bond forming group] under an alkaline condition at a ratio of compound (A) to compound (B) of 1:(0.3 to 1.8) by mol. The present process for producing an organosilicon compound comprises a reaction process of conducting alcohol exchange reaction of a silicon compound SiY 2 4 [wherein Y 2 represents a siloxane-bond forming group] in 1-propanol to produce a composition; and a condensation process of adding a silicon compound R 0 Si(R 1 ) n X 2 3-n [wherein R 0 represents a (meth)acryloyl group; and X 2 represents a hydrolyzable group] to the composition to perform the hydrolysis copolycondensation of the silicon compounds under alkaline conditions.</p> |
