Abstract: Production of aqueous formulations comprises heating 2-organyl-oxy-, -thio- or -amino-dihydrofuran, dihydropyran, tetrahydrooxepin and tetrahydrooxocin compound(s) in the presence of water and an acid catalyst and (partly) removing the hydroxy, thio or amine compound during or at the end of heating. Production of aqueous formulations comprises heating 2-organyl-oxy-, -thio- or -amino-dihydrofuran, dihydropyran, tetrahydrooxepin and tetrahydrooxocin compound(s) of formula (I) in the presence of water and an acid catalyst and (partly) removing H-X-R3 during or at the end of heating. X = O, S or N-R6; R3, R6 = R, formyl or CO-R or may be combined to a ring if X is N-R6' R = 1-12 C alkyl or an optionally substituted 3-23 C cycloalkyl, 7-13 C aralkyl or 6-14 C aryl group; R1, R2, R4 = H or R or 2 adjacent groups may be combined to a ring; n = 1-4; and R5 = H or R or R4 and R5 or 2 adjacent R5 groups may be combined to a ring.

Abstract: 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.

Abstract: PCT No. PCT/EP90/01539 Sec. 371 Date Mar. 13, 1992 Sec. 102(e) Date Mar. 13, 1992 PCT Filed Sep. 12, 1990 PCT Pub. No. WO91/04514 PCT Pub. Date Apr. 4, 1991.A process for the reversible or irreversible production of an image by imagewise exposure of a recording layer to energy in the presence or absence of an electrical and/or magnetic field, resulting in a pattern of surface charges on the surface of the recording layer corresponding to the imagewise exposure to energy. The recording layer consists essentially of an organic material which solidifies in a glass-like manner, is non-photoconductive or substantially non-photoconductive and contains permanent dipoles, in which the pattern of surface charges is produced without or substantially without the formation of free charge carriers by reversible imagewise alignment of at least some of the permanent dipoles present in the recording layer. The process is advantageously carried out using an apparatus which comprises a suitable recording element, devices for imagewise exposure of the recording layer of the recording element to energy, and a counter-electrode which is in direct contact with the recording layer and can be removed therefrom. The pattern of surface charges produced by the process can be toned with liquid or solid toners. The resultant toner image can then either be fixed on the recording layer or transferred from the recording layer to another surface, after which the pattern of surface charges can be erased by exposing the entire surface to energy. A further image can then be produced. In this way, photocopies can be produced without the need to use the high-voltage sources which are necessary in conventional electrophotographic processes.
