Claims
- 1. A thermosensitive recording method, comprising;
- providing a first recording sheet pre-treated with a compound A, and a second recording sheet pre-treated with a compound B, and placing said first recording sheet upon said second recording sheet to form a set of recording sheets,
- heat-treating said set of recording sheets resulting in sublimation or evaporation of compound B to bring these two compounds into contact with each other on said first recording sheet, resulting in a latent image on said first recording sheet, and
- exposing said first recording sheet to light to produce a color image on said first recording sheet corresponding to said latent image.
- 2. A thermosensitive recording method according to claim 1, wherein said compound A is at least one compound selected from materials forming free radicals.
- 3. The thermosensitive recording method of claim 2, wherein said compound B is sublimed onto said first recording sheet, which has been pre-coated with at least one of said materials forming free radicals, to allow the reaction thereof with said materials on said first recording sheet.
- 4. The thermosensitive recording method of claim 2 wherein compound A is selected from the group consisting of carbon tetrachloride, carbon tetrabromide, dibromomethane, iodoform, chloroform, bromoform, bromochloroform, hexachloroethane, tetrachloroethylene, trichloroacetophenone, tribromoacetophenone, p-nitrobenzotribromide, benzotrichloride, hexachlorobenzene, hexabromomethylsulfone, hexachloromethylsulfone, N-tribromomethyltriazine, tribromomethylphenylsulfone, tribromoacetic acid, tribromoethane, and tribromoethylene.
- 5. A thermosensitive recording method according to claim 1 wherein said compound B is at least one compound selected from aromatic amines.
- 6. The thermosensitive recording method of claim 5 wherein compound B is selected from the group consisting of aromatic amines, indoles, azobenzenes, quinolines, naphthoquinones, imidazoles, diphenylamines, styrile bases, triphenylamines, N-vinylcarbazoles, carbazoles, pyridine, isoquinoline, pyrimidine, pyridazine, pyrazine, cinnoline, quinazoline, pyrrole, pyrazole, and oxazole.
- 7. The thermosensitive recording method of claim 1, wherein said compounds A and B pre-coated on a set of recording sheets are evaporated onto said first recording sheet, resulting in a color image on said first recording sheet.
