Reproduction material for the diazotype

This invention describes diazotype material and methods BU its manufacture and use and refers eich in special to a heat developable two-component diazotype photosensitive material and Process for its manufacture and use.

Diazotype material is widely used in industry, da s good «combines quality with low costs« Zwei Types are used in general! Material for semi-wet development and dry development material. at dsr half-humid development type you need one liquid developer. Used in trooken development instead Asasoniakdänpfe.

parts · This is why other methods of reproduction were sought, for example those »which only require the application of heat to produce images. However, there are other disadvantages associated with these, ζ „Β. that the sensitivity to heat is retained even after the desired production has been established.

The present invention connects the gate parts of the Diaactypia process with those of the thermographic process j, whereby a few disadvantages of both methods are avoided will. The quality and low cost of the diazotype process unite here with the simple development method the thennographic process. The use of liquid developers and gaseous ammonia is avoided and the final reproduction is insensitive to further exposure to heat.

The present invention therefore relates to a heat developable it light-sensitive diazotype material which does not have the disadvantages of the previously known diazotype materials Has·

After the original has been removed, both can be heated to a temperature which lies between the activation temperature of the thermosensitive, basic substance-releasing agent and the scorching temperature of the support for the reproduction material. Temperatures of about 140 ° to 160 ⁰ O have proven to be suitable for development.
