Abstract: Dye preparations containing a low-mol. wt. poly-tetrahydrofuran (C1), optionally in combination with hardly-volatile, water-soluble or water-miscible organic solvent(s) (C2), in addition to a dispersed dye (A1) or dissolved dye (A2), a dispersant (B) if (A1) is present, and water (D). An Independent claim is also included for a method for printing flat or 3-dimensional substrates by the ink jet technique, in which dye preparations as described above are printed onto the substrate and the print is then fixed if required.

Abstract: A dispersing agent is prepared from a di- or polyfunctional isocyanate, a polymeric compound or homopolymer containing a functionalized chain end or a phosphoric acid ester. A dispersing agent (I) is obtained by reaction of: (A) of a di- or polyfunctional isocyanate with: (B) a polymeric compound having a chain terminated by a group, XH where X is COO, O, S or NR and R is a 1-6C alkyl, (C) a homopolymer terminated by a group, YH prepared from monomers consisting of N-vinylamides, N-vinyl lactams, vinyl and/or alkyl substituted nitrogen containing heterocycles or copolymers, optionally containing further monomers where Y is COO, S or NR and R is a 1-6C alkyl, or (D) a phosphonic acid ester containing a group, YH. Independent claims are included for: (i) a pigment composition containing a pigment, the dispersing agent (I) and optionally other additives (ii) an ink (II) for use in ink jet printing comprising an aqueous ink, a pigment and a dispersing agent (I) and (iii) a process for printing substrates by ink jet printing by means of the ink (II).

Abstract: Process for the bulk colouring of paper with pigments and fixing agents, where the pigment and the fixing agent are added simultaneously to the paper mass to be coloured and a cationic fixing agent is used as the fixing agent in a quantity of 0.01 to 3.0% by weight, based on the dry paper mass to be coloured.

Abstract: The invention relates to the use of plate-shaped made of components made of open-celled foam materials, especially coloured black, based on a melamine resin condensation product as an absorber in solar collectors. Transparent cover plates are then arranged on the sun side of the components in front such that a heat exchange medium, especially air, can be conducted through the components and also through channels formed by the cover plates and the components.

Abstract: The invention relates to a method for producing polymer coated pigment particles, whereby a solution of a polymer in a first solution is mixed with a second solution, wherein the polymer is insoluble or is hardly soluble, in the presence of finely distributed pigment particles. The choice of polymer enables the pigment particle to be modified as desired.
