    • The invention concerns compositions to simultaneously tan and dye hides, characterized by the fact that they contain at least one tanning compound able to form chromophore groups consisting of at least one member of the group including :
         natural pyrocatechic derivatives of quebracho, mimosa, acacia and their tannic acids ;
         natural pyrogallic derivatives of tara, carob and their tannic acids ;
         naphthalene sulphonic acid condensed with formaldehyde ;
         naphthalene sulphonic acid ;
         phenolsulphonic acid ;
         phenolsulphonic acid condensed with formaldehyde ;
         gallic acid ;
         and at least one coupler able to develop with the chromophore groups of the compound tanning the final colour, this coupler belonging to the group including :
         triphenyl-methano-sulphonic acid ;
         aniline ;
         p-amino-aceto-aniline ;
         urea-1 acid ;
         p-amino-salicylic acid ;
         di-nitro-styrene-sulphonic acid ;
         p-sulphanilic acid ;
         p-nitro-aniline
         phenolsulphonic acid ;
         benzidine H ;
         benzaldehyde ;
         N,N dimethyl-aniline ;
         o-dianisidine Ch-CH.
    • 本发明涉及组合物,以同时黄褐色和染料的生皮,由thatthey含有能够形成发色团组成的群组包括以下中的至少一个成员的至少一种化合物鞣制的事实为特征:克夫,含羞草,阿拉伯树胶及其天然衍生物pyrocatechic 单宁酸等; 塔拉,角豆及单宁酸等自然邻苯三酚衍生物; 萘磺酸与甲醛缩合; 萘磺酸; 苯酚磺酸; 苯酚磺酸与甲醛缩合; 没食子酸; 和至少一个耦合器能够与鞣制的最终颜色的化合物的发色团的发展,这种联接器属于该组的,包括:三苯基甲基 - 磺酸; 苯胺; 对氨基乙酰苯胺; 脲 - 1酸; 对氨基水杨酸; 二硝基 - 苯乙烯磺酸; 对 - 氨基苯磺酸; 对硝基 - 苯胺苯酚磺酸; 联苯胺H; 苯甲醛; N,N-二甲基苯胺; 邻联茴香胺CH-CH。 我妮
