| 1990 | Invention patented by Keizo Koya, Kozo Sato, Yoshiharu Yabuki, and Hiroshi Hara on April 31th, 1990. Abstract: A novel color image recording method is provided, which comprises exposing to light a light-sensitive material obtained by dispersing a composition containing at least a photopolymerization initiator, a color image-forming substance and a polymerizable compound in a hydrophilic binder and then coating said dispersion on a support, subjecting said polymerizable compound in the exposed portions to polymerization, and then (a) eluting said color image-forming substance contained in the unpolymerized polymerizable compound in the unexposed portions with an alkaline aqueous solution or (b) subjecting said color image-forming substance contained in the unpolymerized polymerizable compound in the unexposed portions to chemical change so that it is discolored, thereby forming dye images. |
| 1994 | Invention patented by Yasuko Sonoda on January 10th, 1994. Abstract: A half tone color image recording method is provided in which picture cells of a same main scanning line are staggered such that every second picture cell is shifted in a sub scan direction orthogonal to the main scan direction in one or two of three colors. Simultaneously, in the other two colors or in a remaining one color, every second picture cell group consisting of two adjacent picture cells of the same main scanning line is shifted in the sub scan direction. The amount of staggering or shifting corresponds to a half length of the picture cells in the sub scan direction. |
