Description

Przedmiotem niniejszego wynalazku jest sposób przygotowania ciemno-czerwonego barwnika, nie posiadajacego powyzszych niedogodnosci. Sposób ten polega na dwu rozmaitych operacjach, a mianowicie: nasy¬ caniu skóry barwnikiem, który dzieki swym czesciom skladowym daje podklad nieroz¬ puszczalny, i zastosowaniu po wygladzeniu skóry powloki, która dzieki swym czesciom skladowym daje pozadany polysk. Plyil, sluzacy do nasycania skóry, otrzymuje sie przez zmieszanie fuksyny krystalicznej (chloro-wodorek rozaniliny) z fioletem (chloro-wodorek penta-metylo-rozainiliny) w stosunku zaleznym od majacego sie o- trzymac odcienia. Plyn ten otrzymuje sie przez rozpuszczenie: 33 czesci barwnika w 500 czesciach wrzacego alkoholu metylowe¬ go 90° i przez zmieszanie z drugim roztwo¬ rem, zawierajacym 20 czesci taniny w al¬ koholu metylowym, 450 czesci alkoholu wrzacego 90°, 50 czesci nitrobenzolu C6H5N02 w celu zwiekszenia napiecia po-1 wierzchniowego i zdolnosci przepajania barwnika.Co zas do powloki, to sporzadza sie ja prz£z uzycie mieszaniny fuksyny (chloro-wodofeferóza^ifty) i fioletu, przyczem rozpuszcza sie 30 g barwnika w 500 cm3 alr koholu 90° i ogrzewa sie do wrzenia, dopó¬ ki sie wszystko nie rozpusci. Do tego rozr tworu dodaje sie 23 g taniny w alkoholu i gotuje 10 minut. Nastepnik dodaje sie 50 g gumilaki bialej w luskach, które rozpu¬ szczaja sie przez powolne gotowanie w cia- gu 15 minut. Wszystko potem rozciencza sie do 1 1 przez, dodanie 500 cm3 alkoholu metylowego.Ostateczne wygladzenie skóry moze byc ulatwione przez dodanie do powloki lub po¬ litury 10% alkoholu metylowego, ale ten dodatek nie jest konieczny. Odcienie bar¬ wy—eieffiso-czerwonej zaleza od stosunku fioletu do fuksyny i mozna otrzymywac barwtók&d bardziej zielonego (tylko fuksy¬ na) do bardziej rózowego (sam fiolet).Mozna zmieniac stezenie politury w zalez¬ nosci od gatunku skóry i pory roku, ponie¬ waz w lecie politura latwiej sie ulatnia i powinna byc bardziej rozcienczona. PLThe present invention relates to a method for the preparation of a dark red dye without the above drawbacks. This method consists of two different operations, namely: saturating the leather with a dye which, thanks to its constituents, gives an insoluble base, and after smoothing the leather, a coating which, thanks to its constituents, gives the desired gloss. Plyil, used to saturate the skin, is obtained by mixing crystalline fuchsin (rosaniline hydrochloride) with violet (penta-methyl rosainiline hydrochloride) in a ratio depending on the shade to be used. This liquid is obtained by dissolving 33 parts of the dye in 500 parts of 90 ° boiling methyl alcohol and by mixing with a second solution containing 20 parts of tannin in methyl alcohol, 450 parts of 90 ° boiling alcohol, 50 parts of nitrobenzole C6H5NO2. in order to increase the surface tension and the dye permeability. As for the coating, it is prepared using a mixture of fuchsin (chloro-hydropheresis ^ ifty) and violet, and 30 g of dye is dissolved in 500 cm3 of alcohol 90 ° and heated to boiling until everything is dissolved. To this solution, 23 g of alcohol tannin are added and boiled for 10 minutes. 50 g of white gum shells in their shells are added, which are dissolved by slow cooking for 15 minutes. Everything is then diluted to 1 liter by adding 500 cc of methyl alcohol. Final skin smoothing can be facilitated by adding 10% methyl alcohol to the coating or polish, but this addition is not necessary. The shades of eieffiso-red depend on the ratio of violet to magenta and you can get a dye greener (magenta only) to pinker (violet only). You can vary the concentration of the polish depending on the type of leather and the season of the year. May in summer, the polish flows off more easily and should be more diluted. PL

Claims

Patent claims. I 1. The method of producing a dark red dye, characterized by the fact that fuchsin (rosaniline chlorohydride) is mixed with violet in a ratio depending on the shade that is to be achieved, and dissolves the strength of 33 parts of the dye in 500 parts of boiling of methyl alcohol after adding to this solution 20 parts of tannin in alcohol, dissolved in 450 parts of boiling alcohol at 90 °, while the surface tension and saturation capacity of the products are increased by adding 50 parts of CQH5NO2 iitrobenzol to the saturation solution skin.

2. The method of producing the dark red dye, characterized by the use of a mixture of fuchsin (rosaniline hydrochloride) and violet, dissolving 30 g of the dye in 50 g of boiling ethyl alcohol at 90 °, heating the whole until completely dissolved and adding then to this solution of 30 g of tannin in alcohol, boiling for 10 minutes, then adding 50 g of pale gumball in shells, dissolving on slow cooking for 15 minutes, and finally diluting it completely to 1 l by adding 500 cm3 of alcohol, whereby the obtained product serves either as a coating or as a final polish.

3. The method of producing dark red dye, characterized according to claim 2 by adding 10% amyl alcohol to the polish to facilitate a final smoothing of the skin.

4. The method of applying these two solutions before and after smoothing the leather, the significant point that these liquids can be used both for dark red tinting of the leather as well as for the preservation of leather shoes of this kind, Societe Anonyme des Anciens Et ablissements A.
