METHODS FOR PREPARING ORGANIC-INORGANIC HYBRID, HARD COATING LIQUID COMPRISING THE HYBRID, AND HARD COATING THIN FILM USING THE LIQUID

摘要

PURPOSE: Provided is an organic sulfur-silicon oxide hybrid, a hard coating liquid containing the same, and a method for forming a thin film of hard coating using the same. CONSTITUTION: The organic sulfur-silicon oxide hybrid is prepared by the step of urethane-reacting organic sulfur compound selected from the group consisting of organic sulfur compound having at least difunctional thiol group(-SH) at its ends, organic sulfur compound having at least monofunctional thiol group(-SH) and at least monofunctional hydroxyl group(-OH), and aromatic organic sulfur compound having at least monofunctional thiol group(-OH), aromatic group and at least monofunctional hydroxyl group(-OH) with alkoxysilane compound having isocyanate group(-NCO) in its molecule in the presence of catalyst.
