Abstract

This disclosure relates a low cost xerographic copier or printer using coated paper. The copy paper is coated with a photosensitive material. This material would be similar to the Diazo coating used in the blueprint process. The copy paper would also include micro-encapsulated bubbles within the fibers of the paper. These bubbles could be similar to those used in National Cash Register's "carbonless" carbon paper. These bubbles would be filled with developrnent solution.

This disclosure relates a low cost xerographic copier or printer using coated paper. The copy paper is coated with a photosensitive material. This material would be similar to the Diazo coating used in the blueprint process. The copy paper would also include micro-encapsulated bubbles within the fibers of the paper. These bubbles could be similar to those used in National Cash Register's "carbonless" carbon paper. These bubbles would be filled with developrnent solution.

A latent irnage would be formed on the copy paper by "burning away" unwanted coating as is done in the Diazo process. The operation of "burning away" the coating could be done with light from a laser for a printer, or conventional optics for a copier. After the latent image is formed, pressure would be applied to the copy paper which would break the bubbles and allow the enclosed developrnent solution to dampen the paper and develop the latent image. The developer reacts with the remaining coating to form a visible image. The development solution would then evaporate. The pressure could be applied to the copy paper by passing it through the nip of two pressure rollers.

Alternatively, the bubbles could be supplied on a second development sheet or web which would be compressed with the copy paper. Bubbles could also be supplied in bulk and applied to the copy paper at the compres...
