10 results about "Photographic paper" patented technology

Photographic paper is a paper coated with a light-sensitive chemical formula, used for making photographic prints. When photographic paper is exposed to light, it captures a latent image that is then developed to form a visible image; with most papers the image density from exposure can be sufficient to not require further development, aside from fixing and clearing, though latent exposure is also usually present. The light-sensitive layer of the paper is called the emulsion. The most common chemistry was based on silver salts (the focus of this page) but other alternatives have also been used.

Photosensitive film composite image medium, preparation method and application

The invention belongs to the technical field of image materials, and particularly relates to a photosensitive film composite image medium, a preparation method and application. Comprising the following steps: S1, exposing a photosensitive film to obtain an overexposure film; s2, carrying out reverse flushing on the overexposure film to obtain a visual image; and S3, attaching the visible image to the reflector to form the photosensitive film composite image medium. The invention provides a brand new photosensitive film processing method. And carrying out overexposure treatment and reverse flushing, and tightly attaching the obtained low-density film to a reflector (such as photographic paper) like a film to form a complete complex. The method breaks through the tradition that the photosensitive film must be watched by backlight. By compounding the processed film and the reflective base material, the obtained complex realizes a reflective image watching function, so that a final image work can be directly appreciated under common indoor light and gallery light like an oil painting and a common photo, and the application scene and the display flexibility of the image work are greatly expanded.
