It had been found that the dyestuff of the formula ##STR1## is very suitable in a differential dyeing process for the dyeing of polyamide fiber materials at a pH of 2 to 9; the dyestuff possesses a very good differentiating behavior and migrating behavior yielding dyeings of a high degree of evenness while it does not dye accompanying non-polyamide fibers, not even in traces.

Preparing suede-like leather sheet materials by passing a napped sheet with a fluid through a venturi-nozzle having a predetermined inner area. The sheet has naps of superfine denier fiber at least on one surface, and comprises (a) a non-woven fabric made up to 0.01-0.3 denier superfine staple fibers of breaking strength below 3 grams and an elongation at break of 60180 percent and (b) a polyurethane elastomer obtained by reacting a diol mixture by weight of about 20-40 parts of polycaprolactone diol of a molecular weight of about 1000-3000 and about 60-80 parts of polytetramethyleneetherglycol of a molecular weight of about 1000-3000 with an organic diisocyanate and a diamine chain extender.

A PROCESS FOR INCREASING THE RESISTANCE TO RUBBING AND CROCKING OF DARK SHADES OF FABRIC SUCH AS WOOL, POLYESTER, AND THE LIKE. PROTECTION OF THE SURFACE OF THE DYED GOODS IS AFFECTED BY PADDING WITH AN AQUEOUS DISPERSION OF COLLAGEN OF MOLECULAR WEIGHT FROM ABOUT 20,000 TO ABOUT 80,000. THE PADDED MATERIAL IS THEN DRIED. WHEN A FINISH OF MAXIMUM RESISTANCE TO WATER IS DESIRED, A FORMALDEHYDE PRODUCING COMPOUND, SUCH AS UREA FORMALDEHYDE RESIN, TRIOXANE, AND THE LIKE, CAN BE ADDED TO THE BATH OR CAN BE USED IN THE FORM OF AN AFTER TREATMENT. THE EFFECT IS TO PARTIALLY TAN THE COLLAGEN, RENDERING IT HIGHLY WATER RESISTANT.

A reactive ink for printing. A reagent in the ink reacts with a second reagent. A resultant product of the reaction of said first reagent with said second reagent is a polymeric material that is present on the substrate. A heat activated colorant or colorants, such as a sublimation dyes, are applied to the substrate. The heat activated dye has an affinity for the polymeric material, and the heat activated dye binds to the polymeric material upon heat activation of said heat activated dye.
