Abstract
A paint composition includes a raw polymer, and a dry solvent for dissolving the raw polymer. The raw polymer is composed of a transparent polymer having a hydroxyl group, and polysilazane. The polysilazane is included in an amount of 10% by weight or more with respect to the entire raw polymer taken as 100% by weight. Also disclosed are a process for producing a transparent protective film using the paint composition, and organic glass using the same. Note that the organic glass exhibits a surface hardness of 0.4 GPa or more.
