摘要： A hydrosilylation inhibitor comprising a reaction product of (1) a titanium compound having an alkoxy group in its ligand, and (2) an organosilicon compound having at least one hydrogen atom bonded to silicon atom per molecule is provided. This hydrosilylation inhibitor exhibits inhibitory activity for catalytic activity of a PGE (platinum group element)-bearing hydrosilylation catalyst in an oxygen atmosphere of up to 100 ppm and/or a moisture atmosphere of up to 100 ppm. By using the present invention, catalytic function of the hydrosilylation catalyst is reliably inhibited in the absence of oxygen and moisture while the same catalytic function is easily provided in the presence of the oxygen or the moisture.
