Bast AVAILABLE! ourt Patented Feb. 18, 1947 LIGHT SENSITIVE DIAZOTYPE COM- POSITIONS AND PROCESS Andr Schoen, Easton, Pa., assignor to General Aniline & Film Corporation, New York, N. Y.,

17 Claims.
The present invention relates to light sensitive photographic printing material, compositions and to the process of preparing prints therefrom.
It is an object of the invention to prepare photographic printing materials in which the color may be developed by a suitable after-treatment.
Another object of the invention is the production of photographic coatin material of good stability in the dark and capable of being developed by metal salts or diazo compounds.
A .further object is the provision of photographic material capable of development by diazo compounds and which are of particular value in producing dark shades of high visual density.
Another object is the provision of photographic material and the process for preparing negative prints from a pattern, or image to be reproduced, infwhich the image is developable by metal salts or diazo compounds.
The present invention is based upon the discovery that the arylsulfonyl compounds of aminonaphthol, sulfonic acids, upon exposure to light acquire the ability to reduce metallic salts or to couple with diazo compounds. In utilizing this discovery in the practice of my invention, I coat a suitable base, carrier or support with an arylsulfonyl compound of an aminonaphthol sulfonic acid, and expose the-coated carrier to light under a suitable patternydesign' or picture to be reproduced, whereby the compound in those areas exposed to light is decomposed. The image in ,the light exposed areas then is subjected to a suitable treatment, for example, with metal salts or a suitable diazo compound, the latter treatment preferably being carried out in neutral orslightly alkaline solution, to develop a colored negative. The colors developed generally range from red through blue to black, dependin on the particular aminonaphthol sulfonic acid employed and on the metal salt or diazo compound with which it is reacted. The term negative as herein employed is used relatively to the pattern or print which it is desired to reproduce, regardless of whether that pattern or print is itself a positive or a negative.
Where it is desired to employ diazo compound to develop the color, I employ the arylsulfonyl compounds of those aminonaphthol sulfonic acids which in the free state'are capable of coupling with dia zo compounds. The arylsulfonyl compounds of such aminonaphthol sulfonic acids wherein ArSOz represents the residue of an arylsulfonyl group and n is a whole number of greater than zero. This formula is not intended as limiting or defining the orientation in the naphthalene nucleus of the various substituents. The action of light is believed to cause hydrolysis of the ester, and in some cases also hydrolysis of the amide, resulting in the restoration of the coupling capacity of the aminonaphthol sulfonic acid.
In those cases where the action of light serves to hydrolyze both the ester group and the amide group, the image may be developed by treatment with a reducible metal salt to develop the color, with or without a subsequent fixing treatment. In those cases where the action of light hydrolyzes the ester and not the amide, the image is developed by treatment with a diazo compound. Where it is desired to develop the image by treatment with a diazo compound, it will, of course, be understood that only those aminonaphthol sulfonic acids which in the free state are capable of coupling with diazo compounds are suitable.
Examples of the aminonaphthol sulfonic acids which in the form of the arylsulfonyl compounds are suitable for practicing the present invention are the metathetical Lil-aminonaphthol sulfonic acids, and 2,l-aminonaphthol sulfonic acids, such as 1-amino-Z-naphthol-l-sulfonic acid, the 1? amino-S-naphthol sulfonic acids, such as 1- amino-8-naphthol-3,6-disulfonic acid, l-amino- 8-naphthol-2,4-disulfonic acid, l-amino-B-naphthol5,7-disulfonic acid, l-amino-S-naphthol-dsulfonic acid, the 2-amino-8-naphthol sulfonic acids, such as Z-amino-8-naphtho1-6-su1fonic acid and 1-amino-5-naphthol-2,'7-disulfonic acid, I prefer to employ in the practice of my invention aminonaphthol sulfonic acids wherein the hydroxyl group is in an alpha position and the amino group is in a difierent nucleus and which have a free position para to the hydroxyl gr'dup'g In some of such compounds, it is preferable to also have an alpha position occupied, as forex ample, by a sulfonic group, whether this position be para to the alpha amino group or ortho to a beta amino group.
The arylsulfonyl compounds of aminonaphthol sulfonic acids employed in the present invention may be prepared in known manner, for example,.
by acting in the dark on an aminonaphtholwith an arylsulfonyl chloride to acidylategthe amino group and esterify the hydroxy group. Suitable arylsulfonyl chlorides for :this purpose .are, ;for. example, benzenesulfonyl: chloride, ltoluenesulfonyl chloride, ohlorotoluenesulfonylchloride, and v the like. For example, there may be pp,- tained the benzenesulfonyl ester "of l-benze ne s ule fonamido-8-naphthol-4-sulfonic acid, or the 2- chloro-p-toluenesulfonyl ester of 1-(2-chloro-ptoluenesulfonamido)-8i1aphthol -3,6- disulfonic acid and the like.
If desired, the coating may :include :a light stable diazo .compound,.as .for example Levamine .Qran-ge .GSA. [-2(3 chlorobenzenediazoamino) p -.sulobenzoic acid] and after exposure .to light for example, in theform of the zinc chloride double salt, t in chloride double salt, cadmium chloride double salt, boron tetrafluoride .double salt, the chloride, sulfate, orthe like. In particular, those diazo compounds which contain one or more etherified phenolic groups are preierred. 'Examplesof diazo compounds that may .be employed are the diazo compounds of diethyl- .aminoaniline, o-dianisidine, o-phenetidin, 4- chloro-2-anisidine, 4-benzoylamino2.5-diethoxyaniline, 4-benzoylamino-2,5-dimethoxyaniline, or
.t oa hydrophilicbase or support of paper, gelatin coated cellulose acetate film or the like,preferably in the torm of the aqueous solution, and the .base so treated is thendried and is ready for. use. In particular, for developing the latent image with metalsalts, I prefer to employ mercury salts and salts of the metals above mercury in the electromotive series, as for example silvernitrate or amm'omacal silver nitrate. Where mercuric salts are employed, I use an after-treatment .with ammonia to develop a black color in the reduced mercurous image.
The invention will be described in greater de: tail in connection with the followinghexamples which are given to illustrate the invention.
Fema 1 salt of o-ethoxybenzenediazonium chloride which "results in the development of a, reddish purple positive. The print is then washed and dried.
