Definitions

  • Labelling compounds to be used with the photo-oxidizing agents include leuco dyes having one or two hydrogen atoms which, when the hydrogen atoms are removed therefrom or when additional electrons are added thereto, are colored to form dyes.
  • leuco dyes having one or two hydrogen atoms which, when the hydrogen atoms are removed therefrom or when additional electrons are added thereto, are colored to form dyes.
  • Examples thereof include aminotriarylmethanes, amino-1,9-dihydroacridines, aminophenoxazines, aminodihydrophenazines, leucoindamines, hydrazines and phenethylanilines, described in US Patent 3,445,234.
  • a suitable one may freely be selected from among known materials which are not deformed by heat in the developing step and have a sufficient dimensional stability.
  • films there may be illustrated, for example, polyester films such as polyethylene terephthalate film and polybutylene terephthalate film; films of cellulose derivatives such as cellulose triacetate film; and polyolefin films such as polystyrene film, polypropylene film and polyethylene film. These may be used as a single film or as a laminate thereof.
  • the thickness of the support films of 20 to 200 ⁇ m in thickness are used.
  • a color-forming aid may be added to the diazo type recording material in the present invention for the purpose of controlling color forming reaction.
  • a basic substance is preferably added, if necessary, for the purpose of accelerating the coupling reaction by rendering the system basic upon thermal development.
  • Temperatures of the tube wall of fluorescent lamp were set at 50°C, 60°C, 70°C, 80°C and 90°C, respectively, and temperatures of the heat roller were set at 100°C, 120°C and 140°C, respectively, to form images. Densities of colored portions and background portions were measured by means of a Macbeth densitometer. Results thus obtained are tabulated in Table 2.

Claims (8)

  1. Procédé de formation d'une image visible à partir d'un matériau photo-sensible contenant une couche de substance organique sensible aux couleurs et un révélateur pour ladite substance, dans lequel le matériau est exposé comme une image à la lumière qui provoque la décomposition locale de ladite substance et est ensuite chauffé à une température causant le développement et/ou la fixation d'une image en couleur visible, caractérisé en ce que, immédiatement avant ledit chauffage, le matériau est chauffé à une température plus basse de 60° à 90°C qui ne cause pas de développement ni de fixation des couleurs.
  2. Procédé selon Revendication 1, dans lequel la deuxième étape de chauffage a lieu à une température de 80° à 150°C.
  3. Procédé selon Revendication 1 ou 2, dans lequel l'étape d'exposition comme une image et la première des étapes de chauffage ont lieu en même temps.
  4. Procédé selon l'une quelconque des revendications précédentes, dans lequel le matériau d'enregistrement comprend un support revêtu d'une couche d'une dispersion de fines particules contenant (a) la substance organique photosensible, (b) une image produite par la photo-décomposition de ladite substance organique photo-sensible et (c) une substance organique d'étiquetage capable de distinguer ces substances l'une de l'autre chimiquement ou physiquement.
  5. Procédé selon Revendication 4, dans lequel au moins l'une des substances (a), (b) et (c) est enfermée dans des microcapsules, la paroi desdites microcapsules étant constituée d'au moins un haut polymère choisi parmi les polyurées et les polyuréthannes.
  6. Procédé selon Revendication 4 ou 5, dans lequel la substance photo-sensible (a) est un composé diazoïque, et ladite substance d'étiquetage (c) est un composant de couplage.
  7. Procédé selon Revendication 4 ou 5, dans lequel la substance photo-sensible (a) est un agent photo-oxydant et la substance d'étiquetage (c) est un leuco-colorant ayant 1 ou 2 atomes d'hydrogène pouvant former un colorant par addition d'électrons ou élimination des atomes d'hydrogène.
  8. Procédé selon l'une quelconque des Revendications 4 à 7, dans lequel le support a une épaisseur de 20 - 200 µm et la couche de revêtement une épaisseur de 2 - 30 µm.
