These carbonyl compounds are reacted with cyclic compounds of general formula (II) in which the variables are defined as follows: X is selected among oxygen, sulfur and N—R8; R3 and R8 are the same or different and are selected among hydrogen, C1-C12 alkyl, C3-C12 cycloalkyl, substituted or unsubstituted, C7-C13 aralkyl, C6-C14 aryl, substituted or unsubstituted, formyl, CO—C1-C12 alkyl, CO—C3-C12 cycloalkyl, substituted or unsubstituted, CO—C7-C13 aralkyl, CO—C6-C14 aryl, whereby in the event X═N—R8, R3 and R8 can be bound to one another while forming a ring; R4, R5 and R6 are the same or different and are selected among hydrogen, C1-C12 alkyl, C3-C12 cycloalkyl, substituted or unsubstituted, C7-C13 aralkyl, C6-C14 aryl, substituted or unsubstituted, whereby two adjacent radicals at time can be bound to one another while forming a ring; n represents a integer ranging from 1 to 4, and; R7 is the same or different and is selected among hydrogen, C1-C12 alkyl, C3-C12 cycloalkyl, substituted or unsubstituted, C7-C13 aralkyl, C6-C14 aryl, substituted or unsubstituted, whereby two adjacent radicals R7 at time can be bound to one another or R6 or R4 can be bound to adjacent R7 while forming a ring.

    摘要： A semifinished leather product is produced from an animal hide by pretanning with the use of a chromium-free tanning agent and of a clay mineral which, after stirring for 30 minutes in water at 50° C. at a circumferential rotor speed of from 5 to 25 m/s, has a number average particle diameter of less than 2 μm or a bimodal particle size distribution with a first, finely divided fraction whose number average particle diameter is less than 0.5 μm and a second, coarser fraction whose number average particle diameter is less than 5 μm, determined in each case by the method according to ISO 13320-1, by combined laser light diffraction and light scattering, a proportion of the first, finely divided fraction being from 10 to 90% by weight, and drying of the pretanned animal hide to a water content of from 5 to 45% based on the total weight of the semifinished leather product.
