Abstract: The invention concerns a process for preparing fine-particle mixtures comprising between 97 and 10 wt % of at least one amphiphilic polymer whose softening temperature is above 35 DEG C, and between 3 and 90 wt % of at least one inorganic solid having a particle size of up to at most 500 mu m. According to this process the two components are heated to a temperature which is above the softening temperature of the polymer. The two components are then mixed, broken down in the molten state and rapidly cooled, to a temperature at which practically no separation occurs. The particles are optionally broken down further at temperatures of less than 50 DEG C such that the particle size is between 50 mu m and 5 mm. The invention further concerns the use of these mixtures as detergent additives.

Abstract: Magnetic ink concentrates are described which consist of a dispersion of superparamagnetic or magnetically hard solid particles which are present in water or in alcohol having a dielectric constant of >/= 20 in the presence of dispersing substances, the dispersing substances (dispersants) being polyelectrolytes which have a molecular weight of between 500 and 100,000 and contain at least two identical or different hetero atoms in the main chain and at least three free carboxyl groups or three free amino groups in the side chain. Such polyelectrolytes are readily biodegradable. These ink concentrates have advantageous properties, especially with regard to stability to sedimentation.

Abstract: The invention concerns condensation products containing N,O-acetal- or carbonamide structures, the products being characterized in that they are obtained by the condensation of (a) compounds containing at least once the structural element (I) or (II) in which X=OH or NHR, R being C1 to C6 alkyl or -CH2-COOH, with (b) aldehydes, ketones or aldehydic or ketonic carboxylic acids to give acetal lactones and by subsequently splitting the acetal lactones with (c) aminocarboxylic acids, primary or secondary amines and/or polyethylenimines to give condensation products containing N,O-acetal- or carbonamide structures. The invention also concerns methods of preparing such products and their use as additives in washing and cleaning agents.
