Abstract
A layer comprising a stain resistant agent is formed on a treated surface of a ceramic product used with water so that a stain resistant treatment is applied to the treated surface. The stain resistant agent includes a silicon-containing functional group combining with the hydroxyl group present on the treated surface by dehydration or dehydrogenation. Consequently, a high stain resistant effect can be achieved from the ceramic product.
