| 摘要 |
The invention provides a water- and oil-repellent stainproofing substance comprising an amorphous monomolecular film of a cured film-forming agent selected from a cold curing polysilazane or polysiloxazane, with excellent hardness, durability and wear resistance. The substance may prevent the occurrence of coherency, even if the film is used on the antireflection films of plastic- and glass-lenses. By the vacuum depositing technique, an easy, short-time formation of the amorphous monomolecular film at a high yield is achieved with no use of freon 113. The present process will not cause any environmental pollution concerning the destruction of the ozone layer.
