t Case 150-5193 If desired a subsequent cross-linking of N-methylol compounds may be carried out in the presence of a catalyst K.
Any kind of tanned leather commonly used as a substrate for dyeing from aqueous media may be used for the process of the invention, particularly grain leather (e.g. nappa from sheep, goat or cow and box leather from calf or cow), suede leather (e.g. velours from sheep, goat or calf and hunting leather), split velours (e.g. from cow or calf skin), buckskin and nubuk leather; further also wool-bearing skins and furs (e.g. fur- bearing suede leather). The leather may have been tanned by any usual tanning method, in particular vegetable, mineral, synthetic or combined tanned (e.g. chrome tanned, zirconyl tanned, aluminium tanned or semichrome tanned). If desired, the leather may also be retanned and/or fatted; for retanning, there may be used any tanning agent conventionally employed for retanning, e.g. mineral, vegetable or synthetic tanning agents [e.g. chromium, zirconyl or aluminium derivatives, oak, quebracho, chestnut or mimosa extract, aromatic syntans, copolymers of (meth)acrylic acid compounds or urealformaldehyde resins].
A fatting step may, if desired, be carried out before, and/or after the treatment with the product (P). For fatting there may be used conventional fatting agents (in particular fat-liquoring agents), preferably from aqueous medium. Such fatting agents include animal, vegetable or mineral fats, oils, resins or waxes and/or their chemical modification products, e.g. hydrogenation, oxydation, saponification, trans-esterification or sulphonation products of animal or vegetable fats and oils, or chlorination and/or sulphonation products of mineral fats or oils, and synthetic fatting agents; neutralization agents may also be employed. For fat-liquoring there are preferably employed aqueous fat- liquor emulsions, in which the fat-liquor is emulsified by means of an emulsifier and/or by chemical modification. Fatting agents and emulsifiers are described e.g. in F. Stather "Gerbereichemie und Gerbereitechnologie", t, k Akademie-Verlag, Berlin, 1967, 4th edition. By the term 'Isulphonationl' for the fatting agents, there is meant generally the introduction of a sulpho group, including also the formation of a sulphato group (= 11sulphating11) and the introduction of a sulpho group by reaction with a sulphite or S02 (= "sulphiting").

Before dyeing or printing the leather may be pre-treated with products (P) (optionally in the form of their acid addition products) and dyeing or printing may then be carried out in conventional way, but according to a preferred feature, the treatment with the products (P) (optionally in the form of their acid addition products) is carried out after dyeing or printing.
In the pre-treatment of the undyed and unprinted leather or in the aftertreatment of the dyed or printed leather, the product (P) (calculated as 100% active substance) is used in amounts in the range of 0.2 to 5% by weight, preferably 0.4 to 3% by weight, referred to the dry weight of the leather, or in amounts of 0.1 to 2.5% by weight, preferably 0.2 to 1.5% by weight, referred to the wet weight of the substrate.

The dyeing may be carried out under conventional conditions, preferably at temperatures in the range of 25-70'C and at pH values in the range of 3 to 9, more preferably 4 to 8. optionally in the presence of conventional dyeing assistants, e.g. of a dye-substantive uptake assistant, such as a highly oxyethylated and optionally quaternated fatty amine or fatty aminoalkylamine. After dyeing the pH of the dye bath is advantageously lowered, preferably to values in the pH-range Case 150-5193 of 3 to 5, more preferably 3.3 to 4; a fatting may advantageously be carried out subsequently to the dyeing.
The after-treatment of the dyeing with product (P) may take place in the same bath in which the dyeing has been carried out, advantageously at acidic pH-conditions, preferably in the range of pH 3 to pH 5, more preferably at pH-values < 4, in particular at pH 3.3 to 4.

The after-treatment may, however, also be carried out in a separate fresh bath, advantageously after having lowered the pH of the dye bath and then having drained off the dye bath. The pH of the fresh bath may range in any suitable scope, e.g. between pH 3 and pH 8, preferably in the pH- range of 3 to 6.5, depending on the pH of the employed product (P); a further acid addition in the fresh bath is in general not required since in this case the leather, when adding the fresh bath, is still soaked with the previous bath which is preferably acidic of pH < 4.
The after-treatment is advantageously carried out in the same temperature range as the dyeing, any fatting and any lowering of the pH value by acid addition, preferably at temperatures in the range of 25-700C, more preferably 35-60C for leather and 25-550C for woolbearing skins.
The treated leathers may then be finished in conventional way.
By the process of the invention, there may be achieved a good buildup of the dyes on the leather and deep shades. The obtained dyeings are distinguished by their good fastnesses, principally light-fastnesses and wet-fastnesses, in particular fastness to sweat, to sea- water and to lake-water and their good shade-stability.

The bath is drained off and the leather is washed for 10 minutes with 800% of water at 50'. The bath is then drained off. 900% of water at 500, 2% of 25% ammonia and 3% of vegetable fatty acids that are partially esterified with methyl (fatting agent) are added and after 15 minutes of rotation 2.4% of the blue dye of formula (IV') are added in 3 portions and at intervals of 10 minutes. 30 minutes after the third dye-addition 5% of 85% formic acid are added also in 3 portions at intervals of 10 minutes (pH = 3.5). 30 minutes after the third acid-addition the bath is drained off. 600% of water at 50 and 3% of the aqueous condensation-product of dicyanodiamide and diethylenetriamine (molar ratio 1/1) in the form of the sulphate according to Example 1 of DE 35 25 104 Al (corresponding to GB 2 163 760 A) but of 55% concentration are added and after 30 minutes rotation the bath is drained off. After washing for 10 minutes with 800% of water at 25 the bath is drained off, the leather is drained, dryed and mechanically finished as conventional.
Examples 8 to 12 The procedure of Example 7 is repeated with the difference that in place of the blue of formula (IV') the following dyes are added:
