Description
United States Patent ARYLGUANIDINE ARENEDIAZOSULFONATES Clilford E. Herrick, Jr., Chenango Forks, N. Y., assignor to General Aniline & Film Corporation, New York, N. Y., a corporation of Delaware No Drawing. Application December 31, 1956 Serial No.'631,424
6 Claims. (Cl. 260-141) The present invention relates to arylguanidine arenediazosulfonates which are photosensitive, solvent-soluble compounds having particular utility in the manufacture of light-sensitive diazotype materials and lithographic plates.
It has become increasingly apparent in recent years i that high molecular weight, photosensitive compounds which are soluble in organic solvents, such as alcohols, esters, ketones, methyl Cellosolve, dimethylformamide, chloroform and the like, have important applications in the diazotype and lithographic fields. Representative of such compounds on which considerable work has already been done are the diazooxides, diazoimides, 3- diazoindoles, 3-diazoindiazoles and nitrones. Each of these fills an important segment of the involved fields, 'but considerable research is under way to find new compounds serving to bridge the hiatus in said fields which cannot be served adequately by the presently known compounds.
It has now been discovered that arylguanidine arene diazosulfonates, which are salts of high molecular weight, are photosensitive, solventsoluble substances having such characteristics. These compounds, because of their attributes, are particularly suitable for use in lithography, i. e., in the manufacture of paper and metal lithographic plates.
Arylguanidine arenediazosulfonates, their preparation and their use in diazotypy and lithography constitute the purposes and objects of the present invention.
The new general class of photosensitive, solvent-soluble substances contemplated herein is typified by the following general formula:
tylaminophenyl, benzoylaminophenyl, phenylacetylaminophenyl and the like; and phenoxyphenyl; phenylthiophenyl; diphenyleneoxide; naphthyl', diphenylenesulfide; benzylphenyl, phenethylphenyl and such aromatic radiice cals starting with said phenoxyphenyl as bear the same substituents as those listed for the phenyl radicals; R being hydrogen or aryl such as phenyl; alkylphenyl such as methylphenyl, dimethylphenyl and the like; naphthyl such as 1- or 2-naphthyl and the like, at least two R's being aryl and at least one R being hydrogen.
The new salts are made by preparing in a known manner the required alkali metal arenediazosulfonate and reacting the same in an aqueous medium with the selected arylguanidine acetate with gentle heating if desired. The arylguanidine arenediazosulfonates separate from the aqueous solution, sometimes as solids, sometimes as oils which later crystallize. The photosensitive solids which have a color ranging from yellow to orange, red or brown are insoluble in water but soluble in such solvents as isopropyl alcohol, acetone and chloroform. They may be, accordingly, coated on a suitable base from such solvents to prepare diazqtype and lithographic materials. 4
