    摘要: Thermally reversible light scattering materials are provided in accordance with the invention including a low melting, polymeric material dispersed in a polymer matrix; a first polymer which upon heating from a temperature below its melting point to a temperature above its melting point changes from a light scattering solid to a liquid, the first polymer being dispersed in a matrix provided by a second polymer to form a light scattering polymer material when cold and a less or non-light scattering material when hot; and thermally reversible light scattering materials which go from light scattering at lower temperatures to less or non-light scattering at higher temperatures. The thermally reversible light scattering materials of the invention can be incorporated in many applications including a window which can reversibly change from a privacy condition to a non-privacy or clear condition; a window which can reversibly change between displaying images or objects to obscuring images or objects; a layer which can reversibly change between being clear and frosted by cycling the temperature of the layer; a reversible display; a temperature indicating material or device.

    摘要: A recording and erasure of a visible image on a reversible heat-sensitive recording medium can be repeatedly performed in a stable condition without failure. The visible image is recorded by a thermal recording head on the reversible heat-sensitive recording medium. The recording medium is provided with an unheated area which is not exposed to heat. The visible image is erased by providing heat by a thermal erasing head. The reversible heat-sensitive recording medium is provided with an unheated area which is unheated by the thermal erasing head. The unheated area substantially extends along at least one of sides of the reversible heat-sensitive recording medium. The unheated area prevents the reversible heat-sensitive recording medium from being warped when a erasing operation is repeated many times.
