The objective of this study was to synthesize a new bifunctional photoinitiator by the reaction between 1‐hydroxy‐cyclohexyl‐phenyl‐ketone and 3‐isocyanato propyl trimethoxysilane (ICPTMS) and examine its capability in the photoinitiation process comparing it with the unmodified photoinitiator. This new photoinitiator also acts as a coupling agent for inorganic and organic phases. Therefore, its effect on the physical and mechanical properties of UV‐curable transparent organic‐inorganic hybrid coatings was investigated. The presence of the new bifunctional photoinitiator and TEOS, increased the abrasion resistance and also improved the hardness of the polymeric films.
