  • Publication number: 20070181857
    Abstract: The object of the invention is to provide an antistatic agent exhibiting an excellent property of preventing film-thinning phenomenon and fogging in chemically amplified resists, an antistatic film using the antistatic agent and a product coated therewith. The antistatic agent comprising the water-soluble electroconductive polymer, the solvent and the water-soluble polymer. By using a water-soluble polymer, especially a water-soluble polymer compound having a polypeptide bond or a specific water-soluble polymer compound having a polyvinyl structure in combination with a water-soluble electroconductive polymer in an antistatic agent, influences on resist (such as fogging, film-thinning phenomenons and dissolution of resist after developing of resist) can be suppressed even when surfactant is added into the antistatic agent for the purpose of imparting coatability inexpensively and easily, while maintaining coatability of the agent.

  • Patent number: 7029768
    Abstract: A food container on which surface titanium oxide particles are fixed, where titanium oxide particles may contain brookite crystals, the material of which the food container is constructed may be stainless steel, and the titanium oxide particles may be bonded using a sintering aid, a binder or both. When the food container is made of glass, satisfactory mechanical strength of the container can be maintained even when the thickness of a wall of the container is reduced. Since titanium oxide particles can be fixed onto a surface of a food container at a temperature as low as 20 to 450° C. by use of a sintering aid, a binder or both thermal deformation of glass forming the food container can be prevented.
