Definitions

  • the present invention relates to light-sensitive layers.
  • German specification No. 111,416, dated April 13, 1899, in the name of Marcel Schoen, and U. S. Patent No. 1,444,469, dated February 6, 1923, in the name of Gustav Kiigel and Heinrich Neuenhaus disclose the use of diazo compounds which, on exposure to light, yield dyestuffs.
  • diazo compounds in the form of their sulfonates which in a free state have a strong coupling power.
  • diazo sulfonates of the following formula:
  • R stands for a benzene or naphthalene radical being substituted or not; and X stands for a metal group, are useful for the present process.
  • the coupling diazo compound may be used as such or in form of double salts with, for instance, inorganic salts as cadmium chloride or the like,
  • the layers claimed herein may, if desired, contain additional substances such as are used in diazo-type printing.
  • the new light-sensitive layers are rather stable and yield a negative copy from a positive pattern 30 or vice versa, when exposed to light under such a pattern.
  • the formation of the picture probably takes the following course.
  • the light decomposes the aromatic diazo compound capable of coupling in such a way that an azo component is formed. Simultaneously it acts upon the diazo sulfonate whereby the latter decomposes while yielding a diazo compound, capable of coupling.
  • This diazo compound acts upon the azo component formed as described above, thus yielding a dyestuff picture, which can be fixed by washing out with water the undecomposed parts which were under the designs of the pattern.
  • the reaction may occur in such a way that first the 5 diazo sulfonate is split into a coupling diazo compoundand this latter is at once decomposed into an azo component by the action of light.
  • the azo component thus formed reacts then upon the coupling diazo component present in the layer I formula:
  • light-sensitive layers containing .as light-sensitive subof strong coupling power in mixture with a diazo sulfonate incapable of coupling, being stable and yielding a negative copy from a positive pattern and vice versa when exposed to light under such a pattern.
  • R stands for a benzene or naphthalene radical, being substituted or not
  • X stands for a metal group, being stable and yielding a negative copy from a positive pattern and vice versa when exposed to light under such a pattern.
