Definitions

  • the present invention relates to light sensitive layers and to a process of preparing them.
  • the arylazide is dissolved in water or in an organic solvent, such as, for instance, alcohol; the solution is then applied on a base, for instance, paper or film.
  • a base for instance, paper or film.
  • dyestuffs are formed at those places wherethe light is allowed to react, whilst the places not exposed to light remain unaltered.
  • a positive picture is obfor instance, gelatine, collodion and other bodies.
  • Mixtures of azides may also be used. it stabilizer, such, as for instance,glucose, tartaric acid and the salts thereof and aromatic sulpho acids, may also be added to the layer. fitter the exposure to light, a simple washing out with water or another suitable sumble is adequate in order to render the pic tures permanent.
  • azido compound may also be employed without the addition of alkali by applying it in an alcoholic solution on paper.
  • the pictures obtained by exposure to light under a negative must in this case be washed with alcohol in order to remove the non-used azido compound.
  • Process of preparing light-sensitive layers upon a suitable base which comprises applying an aryl-azide upon said base.
  • NQX x x wherein the Xs stand for hydrogen atoms some of which may be substituted by OH, COOH, N halogen, aryl, aralkyl, oxalkyl,
  • alkyl an amino group substituted or not or a sulfo group upon said base.
  • Processof preparing light-sensitive layers upon a suitable base which comprises applying an arylazide and a metallic salt used in the diaZo-type processu-pon said base.
  • Xs stand for hydrogen atoms some of which may be substituted by OH, COOH, N halogen, aryl, allryl, aralkyl, oxyalkyl or a sulfo group and a metallic salt used in the diazo-type process upon said base.
  • Process of preparing light-sensitive layers upon a suitable base which comprises applying an arylazide, a metallic salt used in the diazo-type process and a colloid upon said base.
  • Process of )reparing light-sensitive layers upon a suite le base which comprises applying an arylazide, a metallic salt used in the diazo-type process and gelatine upon said base.
  • Ks stand for hydrogen atoms some of "whichmay be substituted by OH, UOOH, N halogen, aryl, alkyl, aralkyl oxy-. alkyl, an amino group substituted or not or a sulfo group.
  • light-sensitive lay-- ers containing a compound of the following formula formula wherein one X may stand for COOH and I one X for OH and the other Xs for H.
  • one X stands for hyd-roxyor amino group substituted or not and the other Xs stand for hydrogen atoms some of which may be substituted by OH, COOH, N halogen,'aryl, alkyl, aralkyl, oxyalkyl or a sulfo group and a metallic salt used in the diazotype process.
