Photosensitive diazo duplicating material

The present invention relates to a photosensitive diazo duplicating material. In particular, the invention relates to a photosensitive Diazo duplicating material that contains a carrier and a layer applied to it, the layer being a light sensitive diaso compound and a coupler, optionally with a fusible material and / or an alkali-supplying agent, in the form of fine parts, which in one film-forming binders are dispersed.

Two types of light-sensitive diazo materials are known, which are commonly used for the manufacture of products of documents, drawings or the like, the Sine is a so-called semi-fire diazo material that after exposure to an alkali developing solution which

The Diazo duplicating materials mentioned in the last two sections can also be brewed in exactly the same way as the conventionally known heat-developable Diaso Terrislf-manufacturing material. That is, each of these materials can duroh exposed to ultraviolet radiation a transparent original and then uniformly heated to about 150 to 200 ⁰ C by means of hot '..alzen what a "clear results" and laterally correct reproduction. Alternatively, reflex copying using infrared radiation can also be used for the material if an opaque original is placed on it, and this enables a desired building production through a single stage. Furthermore, the copying material is also advantageous in that it can be fixed to a light colored film after copying with infrared radiation by allowing it to stand, with the result that a preserved reproduction is completely sioner from fading or discoloration during storage. In contrast, 4asu suffers "ine auroh the" Thermofax "copying process" reproduction (the term "Thermofax" is a registered rarwnselohen of Minnesota Mining & Mfg.
