This invention relates to the preparation of wherein R represents a phenyl nucleus having the amino group in position para or ortho to N, and
Z represents the non-metallic elements necessary to complete a heterocyclic nucleus selected from the group consisting of a morpholine nucleus, and a piperidine nucleus. In addition to the amino group, R can contain one or more nuclear monovalent substituents such as an alkyl group represented by methyl, ethyl, propyl, butyl for example, an alkoxy group represented by methoxy, ethoxy, propoxy, butoxy for example, a halogen such as chlorine, bromine, fluorine, iodine, or a sulphonic acid radical.
We have found that the above described diazo derivatives of N-p-aminophenyl-morpholines and -piperidines are stable compounds under ordinary conditions, but are highly sensitive to light, decomposing more or less completely in proportion to the intensity of the light and the period of exposure. Since they are also capable of condensing with certain aryl compounds, as well as with their own partial decomposition products in the presence of alkaline substances to form intensely colored azo dyes, we have furthere found that these diazo derivatives are valuable as light sensitive components in diazotype copying materials. In the presence of selected coupling components on a suitable support, they yield on exposure to light behind a pattern such as a line drawing, printed matter or similar contrasty subject matter and subsequent alkaline processing, images having dark lines and tones contrasted to almost white or slightly gray or tan fields. As will be more fully apparent from the examples given, we can prepare our new diazotype materials by a number of methods. For example, the base or support carrying or containing the light sensitive compounds can be a paper, a cloth, a film such as prepared from an organic derivative of cellulose, synthetic resin such as a polyvinyl acetal, regenerated cellulose, a glass plateor a sheet of metal, the sensitizing materials being applied by coating, dipping, brushing, spraying, dusting or by any other means known to one skilled in the art. Ordinarily, the sensitizing compounds are applied from solutions containing them, either alternatively with a solution of one or more of the diazo compounds of our invention and a solution of the selected coupling component, or, the compounds can be dissolved in a common solvent and applied as above, usually with an acid compound present as a stabilizer. In some cases, it may be desirable to add a thickening or emulsifying agent to the solution or solutions such as gelatin, polyvinyl alcohol, gum tragacanth, a higher fatty acid glycerylsulfate, and the like. The solution concentrations of the sensitizing compounds can be varied within wide limits, the preferred range being up to about 2% by weight of the diazo compound, and about the same concentration of the coupling compound.
It is an object of the invention, therefore, to provide a light sensitive diazotype copying material which combines the advantages of good keeping qualities, high degree of sensitivity to light, and provides prints which are characterized by good stability, sharpness and contrast.
The aminophenyl piperidine compounds may be prepared by reducing the nitro piperidine compounds prepared in general by the method described in Journal Chemical Society (1927) pages 1113 and 1122. The aminophenyl morpholine compounds may be prepared by condensing the desired aniline compound with a beta-beta-dihalogen alkyl ether such as beta-beta'-dichlorodiethyl ether, sym. dichloro-di-isopropyl ether and other similar kind of haloalkyl ethers.
The following examples further illustrate the preparation and application of our new light sensitive diazotype copying materials.
-EXAMPLE 1 A diazo solution was prepared by treating 5.43 grams of N-p-(aminophenyl) -morpholine hydrochloride dissolved in 0. cs. of water with a slight excess of nitrous acid. A piece of white paper was dipped in this solution for a short period, the excess of solution removed, the paper dried and then dipped in a 1% solution of B-naphthol in ethyl alcohol. The dried sensitized paper was exposed behind a positive to a quartz mercury vapor arc. After a few minutes, the image was developed in an atmosphere of ammonia maintained at slightly higher than room temperature. The positive image obtained at once was dark brown in color on an almost white field.
In place of N-p-(aminophenyl) -morpholine hydrochloride, there may be substituted 9 grams of N-p- (amino-m-tolyl) -m o r p h o l i n e sulfate which produces a dark brown black image on an almost white field turning tan colored after several months, or, there may be substituted approximately 2 grams of N- (4-aminophenyl) morpholine-2-sulfonic acid which yields a dark red image on a pale pink field, or, there may be pholine which, with p-naphthol coupler produces a red image on a pale pink field, and with resorcinol coupler an orange image on a pale tan field.
ExAMrLn 2 The diazo solution prepared as in Example 1 was allowed to stand until a suflicient quantity of the diazonium compound had hydrolyzed to provide a coupler. A piece of white paper was then bathed in the solution, the excess solution removed, and the paper dried. Upon exposure and development, an image was obtained which was dark brown on a tan field turning with time to a black image on a pale gray field.

In the above tables, reference has been made to the procedures for preparing some of the coupling compounds disclosed. These general procedures are briefly described in the following:
I. -benzylamino-1-naphthol was prepared by condensing 5-amino-1-naphthol. with benzaldehyde and reducing the resultant Schifl base catalytically or chemically.
lI(A) 5-acylamino-l-naphthols were prepared by condensing 2 moles of 5-amino-l-naphthol or 2 moles of a 5-alky1amino-1-naphthol with 1 mole of XCl, wherein X represents an acyl group.
(B). By condensing -1 mole of the naphthol compound with 1 mole of XCl in the presence of sodium acetate and acetic acid.
III. Halogenated 5-acylamino-l-naphthols of procedure II were prepared by treatment with sulfuryl chloride or bromine in a suitable solvent.
IV. l-hydroxy-2-naphthamides were prepared by condensing 1 mole of l-hydroxy-2-naphthoyl chloride with 2 moles of a compound having the formula RNHR' wherein R and R may be hydrogen, alkyl or aryl.
Y. 5 (p acylaminobenzamido) -1 naphthols were prepared by condensing a 5-amino-l-naphthol with p-nitrobenzoyl' chloride. reducing the nitro group and then reacting with sodium acetate and X01, wherein X represents an acyl group.
VI. Halogenated 5-(p-acylaminobenzamido) -1- naphthols were prepared by treatment with sulfuryl chloride or bromine in a suitable solvent.
Although the examples of Tables I and II refer particularly to coupling with the diazo derivatives of N-p-aminophenyl piperidine and N-paminophenyl morpholine, respectively, it will be apparent from all the foregoing that similar results can be obtained with the various methyl, halogen, methoxy and sulphonic acid substituted diazo derivatives of these compounds.
