Patented Jan. 20, 1931 iaaasis UNITED STATES PATENT oFFl-cau LYNN A. WATT, OF WEBSTER GROVES, MISSOURI. ASSIGNOB TO HOITSANTO CHEMICAL WORKS, OF ST. LOUIS, HISSOUBI, CORPORATION 01' MISSOURI LEATHER DYE Io Drawing. Application filed Kay 7,
This invention relates to leather dyes of the kind that are used for dyeing shoes. 7
The conventional shoe dye contains aniline or n'itrobenzene, which is used principally as a penetrant or vehicle to carry the dye solution through the finish of the leather into the pores of the leather. These substances are highly toxic, and many cases of aniline or nitrobenzene oisoning, resulting in se- 10 vere illness and eath, have been traced directl to the ractice of dyeing shoes while on t e fect of a person and the practice of wearing shoes within a few hours after they have been dyed with a dye containing aniline 5 or nitrobenzene.
The main object of my invention is to provide a non-toxic leather dye that can be used with perfect safety for dyeing shoes while the are on a persons feet.
nother object is to provide an efficient, non-poisonous shoe dye that can be manufactured at a low cost.
To this end I have devised a leather'dye, particularly adapted for use in dyeing shoes, which is distinguished from conventional shoe dyes, in that a non-toxic substance is used as the penetrant or vehicle to carry the dye solution into the ores of the leather.
I have found that-t e dichlorbenzenes are 10 well adapted for this purpose, the substance that I dye soiiition consisting of orthodichlo'rbenzene'or orthodichlorbenzene containing some paradichlorbenzene. When a mixture of said substances is used it is preferable to havethe orthodiehlorbenzene predominate in the Inadditior to heir! of the kind mentione areeasy to obtain and are relatively inexpensive, as either orthodichlorbenzene or orthbdichlorbenzene'containing some paradichlorbenzene, are produced in the manufacture ofmonochlorbenzene, an
intermediate chemical, or paradichlorbenzene, an important insecticide. No adequate market for the ortho isomer alone or conrefer to useas thellpenetrant for the non-toxic, substances 1927. Serial no. mans.
used as the penetra-nt or vehicle of shoe dyes.
departing from the spirit of my invention.
The following is one formula that may be used'to produce my improved, non-toxic leather (1 e: v -0rthod ic hlorbenzene, approximately 30.0
grams;
.Spirit soluble nigrosine, approximately 7.5 grams;
Red oil (oleic acid), approximately 5.0
grams Denatured'e thyl alcohol, su flicient to make, approximately 100.0 cc.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is; 1
1. A leather dye composition containing a dichlorbenzene capable of carrying a. dye solution into the pores of the leather.
2. A leather dye composition including, as
one of its constituents, orthodichlorbenzene. 3. A composition. for the treatment of leather containing a leather dye material and at least one dichlorbenz'ene. 4. A leather dye composed of the following ingredients mixed in approximately the p'roqtainin some residual paradichlorbenzenehas exist e and it istherefore available as a by product at prices comparable with or lower L3 than the aniline or nitrobenzene heretofore portions specified: 1 -.Orthodichlorbenzene 30.0 grams Spirit soluble nigrosine 7.5 grams Red oil (oleic acid) 4 5.0 grams Denatured ethyl alcohol s'ufiil Y cient to make 1000- cc.
