| titleOfInvention | Multi-color recording materials |
| abstract | Multi-color recording materials where the color forming layers are established on the same side of the support are disclosed. The multi-color recording system may be either of: (1) a two-color recording material comprising a support having provided thereon: (a) a light-sensitive heat-sensitive color forming layer comprising (i) microcapsules containing a leuco dye which is capable of forming a color by oxidation and a photo-oxidizing agent and (ii) a reducing agent; and (b) a heat-sensitive color forming layer having a color forming temperature differing from the glass transition temperature of the microcapsule walls, and which comprises an electron donating leuco dye capable of forming a color of a hue differing from that of the light-sensitive heat-sensitive layer and an electron accepting compound capable of reacting with the electron donating lueuco dye to form a color; (2) a multi-color recording material comprising a support having provided thereon: (a) a light-sensitive heat-sensitive color forming layer comprising (i) at least two types of microcapsules each containing a leuco dye capable of forming a color by oxidization and a photo-oxidizing agent and (ii) a reducing agent, wherein the polymer walls of the at least two microcapsules have different glass transition temperatures from each other, and the leuco dyes contained in the microcapsules have different hues from each other; and (b) a heat-sensitive color forming layer as described above; or (3) a multi-color recording material comprising a support having provided thereon: (a) a light-sensitive heat-sensitive color forming layer comprising (i) at least two types of microcapsules each containing a leuco dye capable of forming colors by oxidation and a photo-oxidizing agent and (ii) a reducing agent, wherein the leuco dyes contained in the microcapsules have different hues from each other, and the photo-oxidizing agents contained in the microcapsules are activated by actinic light of different wavelengths; and (b) a heat-sensitive color forming layer as described above. |
