This invention provides a contamination-resistant float glass showing even quality in durability and its good quality sufficienty. The film for contamination-resistance is formed only on the top-side surface of a float glass. The surface, free from tin diffused from a float bath, can be identified by ultraviolet irradation. A solution including a chemical adsorbent like fluoroalkyltrichlorosilane is applied to the top-side surface by a roller coater. The adsorbent can be prevented from hydrolyzing with dry air around the coating portion of the coater. Surplus solution can be removed with dry air blown on the surface to make the contamination-resistant property and the appearance better. The chemical adsorbent is bonded to the surface via a siloxane bond to form a thin film. The contamination-resistant float glass is installed in the front door of an apparatus like a toaster oven with the film facing the inside of the oven. The film on the top-side surface shows higher contact angles than that on the bottom-side surface in durability tests.

An iron comprising a bottom member as an ironing face, which is provided with a plated metal film containing fluorine compound fine particles, so that the ironing face provides high surface hardness which shows less wear, good slidability and less generation of static electricity.

Process for producting a contamination-resistant float glass

A protective layer which is applied to rewritable optical information recording medium comprising a substrate and a photosensitive thin film. When exposed to optical energy, the thin layer is capable of undergoing a reversible phase change by which an optical reflectivity is changed between two states. The protective layer is inhibiting the thermal damages of the substrate during light irradiation and also controlling thermal and optical boundary conditions. The protective layer is made of the mixture of mutually solid insoluble materials. The typical choice of the mixture of small crystalline grains of ZnS and noncrystalline SiO.sub.2.
