    摘要: The present invention provides a flame-retardant or nonflammable decorative sheet which is a one-piece laminate of the following materials:

    one layer or two or more layers of a sheet material for a core layer, obtained by impregnating a base sheet material made of an inorganic fiber, with a composition comprising a phenolic resin and/or a melamine resin and aluminum hydroxide and/or magnesium hydroxide, the proportions of the former and the latter in the composition being 4-15% by weight and 96-85% by weight, respectively, and
    a sheet material for a decorative layer, placed on at least one side of the sheet material for the core layer. When the sheet material for the core layer consists of two or more layers, there can be interposed, between the layers of the sheet material for the core layer, a sheet material for a reinforcing layer obtained by impregnating a base sheet material made of an inorganic fiber, with a thermosetting resin. The present invention also provides a process for producing such a flame-retardant or nonflammable decorative sheet.
