Definitions

  • the invention relates to a flat, paper-like, in particular sheet or tape-like base for producing a blueprint from a transparent template, consisting of a base layer and a light-sensitive coating arranged thereon on one side.
  • the blueprint paper consists of a sheet or tape-like base layer made of paper, which is provided on one side with a light-sensitive coating made of a diazo compound. After placing the transparent template on the blueprint paper, the same is exposed in a continuous process by daylight or artificial light. It is then developed through the action of ammonia vapors or through the decomposition of trivalent iron compounds into divalent iron compounds.
  • Such blueprints have the disadvantage that they tear very easily in the event of improper use, but especially with frequent use, and thus become unusable.
  • such blueprints are not dimensionally stable, ie the dimensions of the blueprint change with use and the change in atmospheric humidity, so that a so-called "picking up" of dimensions from the blueprint is possible, but is not practical.
  • the base and thus the blueprint are tear-resistant, i.e. it can often be folded and folded and handled improperly without tears.
  • a blueprint created from such a base is dimensionally stable.
  • a section of a flat base 1 is shown in side view, which consists of a transparent template for producing a blueprint.
  • This base 1 consists of a base layer 2 and a light-sensitive coating 3 arranged on one side thereof.
