专利汇可以提供Halogen liberating/color former light sensitive systems having increased speed专利检索,专利查询,专利分析的服务。并且Nonsilver, organic, dry-processed, violet and blue radiation sensitive free-radical films for recording and duplicating applications. The latent image may be optically developed in a period of 2 to 3 seconds by uniform exposure to red and near infrared radiation after an initial exposure in the region of 1 to 10 mj./cm.2 in the violet or blue regions of the spectrum. The image color is close to neutral. Fixing is accomplished by heating the film to a temperature of 150* C. for 60 seconds.,下面是Halogen liberating/color former light sensitive systems having increased speed专利的具体信息内容。

  • 2. A composition according to claim 1 including the compound 2,5-dimethoxy-4''-aminostilbene.
  • 3. A composition according to claim 1 including the compound 4, 4''-methylene-bis-cyclohexylamine.
  • 4. A composition according to claim 1 in which the primary amine is selected from the group consisting of cyclohexylamine, octadecylamine and methylene-bis-cyclohexylamine.
  • 5. A composition according to claim 1 including iodoform as the organic halogen compound and a triphenylmethane compound as the color forming compound.
  • 6. A composition according to claim 5 including a triaryl compound of an element selected from the group consisting of As, Sb, Bi and P.
  • 7. A composition according to claim 5 including an alkyl substituted phenol.
  • 8. A process comprising: a. preparing a thin film containing the composition of claim 1; b. photographically exposing said composition to a dose of blue or violet radiation to which it is sensitive; c. optically developing the latent image which results from step (b) by exposing said film uniformly to radiation in the red and infrared; and d. fixing the resulting visible image by heating the film to about 150* C. for 1 minute.
  • 9. A process for enhancing the shelf life of the film of claim 1 comprising maintaining said film in a vapor consisting essentially of primary alkyl amine while it is stored prior to exposure.
