Abstract: A direct color thermal printing method records a full-color image containing black characters on a thermosensitive color recording medium having three laminated thermosensitive recording layers. Three color components of each pixel are sequentially read out from three color frame memories.

When recording the black pixels, a thermal head is driven to apply a predetermined maximum amount of head energy to the thermosensitive color recording medium, for simultaneously coloring the three thermosensitive recording layers in accordance with the black pixel data.

Abstract: A photographic contact printing process is disclosed having application in the mass production of replicate video discs from a master disc, and other applications wherein it is desired to replicate micro-detail over a relatively large area. A problem with conventional contact printing from a mask to a photographic medium is one of maintaining intimate contact over a relatively large area since dust, dirt, etc., are almost impossible to completely eliminate in any practical manner. In accordance with the present invention, a contact printing process is provided wherein intimate contact is not necessary for making high quality contact prints. The present invention recognizes that in contact printing information from a master disc to a replicate disc, the contact printing process is significantly less sensitive to imperfect contact between the master disc and the replicate disc if one employs a replicate disc comprising a photosensitive material having a certain optical properties.

Abstract: A method of manufacturing a semiconductor device, in which a layer of photolacquer (5) containing as a photoactive component a diazo oxide is provided on a semiconductor substrate. Of this layer, parts (9) are irradiated by a first patterned irradiation (7) and these parts are then rendered poorly developable by an intermediate treatment. Subsequently, the lacquer layer (5) is subjected to a second non-patterned irradiation (11) and is then developed. According to the invention, in the parts (9) irradiated by the first irradiation a pigment is formed, which absorbs radiation having a wavelength at which diazo oxide is photosensitive. The second irradiation is carried out with radiation of that wavelength. Thus, lacquer tracks having a rectangular profile can be obtained in a simple manner.

Dry development in ammonia vapors shows up transparent zones and opaque zones corresponding to the information.

Abstract: Disclosed herein is a method and apparatus for producing color transparencies on a recording element comprising an additive color filter screen having disposed thereon a coating of a visible light-transmissive, invisible light-sensitive, silverless material, preferably a diazo or vesicular material. The method comprises the steps of imagewise exposing a panchromatic auxiliary layer, e.g. a photoconductive layer, to a multicolored object, such exposure being made through the recording element of the invention. This step acts to produce in the auxiliary layer a monochrome image containing color image information of the multicolored object. Next, the silverless material is exposed to invisible actinic radiation, such exposure being made through the monochrome image formed in or on the panchromatic auxiliary layer. This step serves to transfer the color image information from the auxiliary layer to the silverless layer of the recording element.

The light source produces major energy in the range of about 4600 to 5900 Angstroms. A filter or other means is provided to remove any spurious wavelengths which are non-responsive to the blue image and which can expose the diazo paper.
