摘要： 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.

摘要： A method for forming a molecular film includes the steps of: coating a surface of a substrate having active hydrogen atoms on its surface with a coating solution containing a silane-based compound having at least one reactive group selected from the group consisting of a chloro group, an alkoxy group and an isocyanate group; and effecting an elimination reaction between the active hydrogen atoms on the surface of the substrate and reactive groups of the silane-based compound, thereby covalently bonding the silane-based compounds to the surface of the substrate. The substrate is supplied to a chamber in which an atmosphere is maintained at a low water vapor density. The surface of the substrate is coated with a coating solution containing the silane-based compound and a solvent by using a transfer element. A dehydrochlorination reaction is effected between the active hydrogen atoms and the chloro groups of the silane-based compounds. Thereafter, any coating solution containing unreacted silane-based compounds after coating is removed inside or outside the chamber.

摘要： A novel chemical adsorbate compound capable of forming a monomolecular thin film is provided. The chemical adsorbate compound is transparent and stable in the visible light range, and has a photosensitive group which causes a photochemical reaction in the ultraviolet light range. Utilizing the chemical adsorbate compound, a liquid crystal alignment film is also provided. The liquid crystal alignment film has an excellent thermal stability and alignment control performance. Utilizing liquid crystal alignment film, a liquid crystal display device is further provided. The liquid crystal display device achieves wide viewing angles and clear display images at small driving voltages. These are achieved by, as one example, providing a chemical adsorbate compound including a chalcone derivative having a COO group at the 4′ position in the chalcone skeleton and an —SiX3 group, where X is a halogen, at the molecular end adjacent to the COO group. Another example of the chemical adsorbate compound is a compound in which a linear hydrocarbon group is ether-linked at the 4 position of the benzene ring in the chalcone skeleton and an —SiX3 group, where X is a halogen, is ether-linked to the hydrocarbon group.
