A floor panel includes a core and decorative layer applied thereon, such that the material of the aforementioned core has a density of more than 1000 kg/m.sup.3, preferably more than 1300 kg/m.sup.3, and has a thickness of 6 millimeters or more. The core has internal spaces and/or that the core has spaces on its bottom side. A method for manufacturing such floor panels is provided according to the aforementioned floor panel.

An image-decorated sheet including: an image recording sheet; and an image layer formed on an image receiving surface of the image recording sheet with toner using an image forming apparatus, in which the image layer is transferred to a body to be decorated to decorate the body to be decorated, an image-decorated body on which an image is formed by the image-decorated sheet, and an image-decorated body manufacturing method.

Gypsum boards formed from synthetic gypsum and other gypsum sources having high chloride salt concentrations. Gypsum boards may include a board core including set gypsum. A total concentration of the chloride anion in the board core ranges from about 500 ppm to about 3000 ppm, typically about 1000 ppm to about 3000 ppm, based on weight of the calcium sulfate hemihydrate. An inner surface of a front paper cover sheet contacts a first face of the board core. An inner surface of a back paper cover sheet contacts a second face of the board core. A starch layer coats the inner surface of at least one of the front and back cover sheet. Methods of making the gypsum board, and a wall system for employing the gypsum boards, are also provided.
