摘要： A method of forming visible images on a differentiated background comprises the application of thermal energy to a coating of metastable metal colloid on a support. Thermal energy is able to convert the metastable metal colloid to a stable spheroidal form. Computer control of a laser beam or thermal print head can be employed to provide highly resolved images carrying graphic, digital and textural information.

摘要： A photographic element according to the invention includes a reflective support, one or more photosensitive silver halide emulsion layers, and a colored antihalation layer interposed between the support and the photosensitive layers. The antihalation layer comprises thin grains of silver in the form of platelets having a thickness of up to about 20 nm. The platelets are distributed in a suitable matrix or colloidal medium such as gelatin. The thinness of the platelets allows the antihalation layer to be formed effectively at lower silver levels.

摘要： Apparatus is disclosed for recording and reading a color image formed on a receiving medium such as a film coated with a blue metastable colloidal silver. Upon application of heat to selected areas of the coating, the blue silver turns yellow to form an image. In a record mode, a modulated beam from a diode laser is scanned onto the receiving medium to form an image. In a read mode, a diode laser beam containing two different wavelengths of radiation is scanned across an image on the recording medium. In order to detect errors in the image, a detector senses the two wavelengths at each pixel and produces signals indicative of the densities of the yellow and blue in the pixel. Signal processing means is adapted to determine valid data points from the two signals.

摘要： A particulate metastable Group Ib metal colloid is prepared is formed by plating a Group Ib metal onto small nuclei in a suspension to form non-spherical particles of varying color. The preparation is stable below about 100.degree. C., but when coated onto a support, can be used to form a visible image by application of thermal energy.
