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: Described is a process for preparing polymer-enrobed pigment particles, which comprises mixing in the presence of finely dispersed pigment particles a solution of a polymer in a first solvent with a second solvent in which the polymer is substantially insoluble. The pigment particle can be specifically modified by judicious selection of the polymer.

Abstract: Gels for thermotropic sheets are claimed which are obtd. by light-radiation of a mixt. comprising (A) a non-crosslinked polymer (pref. 5-40 wt.%); (B) a radically-polymerisable monomer (pref. 1-30 wt.%); and (C) water and/or an org. solvent (pref. 30-94 wt.%). Pref. a photoinitiator is opt. also present. Polymer (A) has transparency changes in a 10 wt.% aq. and/or org. solvent soln. and is poly-N-vinylcaprolactam, a copolymer contg. at least 20 wt.% N-vinylcaprolactam, or a polyvinylether. Monomer (B) forms a 3-D network on light-irradiation and ether does not have thermotropic properties of the type specified above or has such properties at at least 20 degrees C above the switching region for polymer (A). (C) is water.

Abstract: Shaped part based on supercritically dried silica aerogel parts in the form of spherical particles having diameters of from 0.1 to 10 mm or of sheet-like pieces having thicknesses of from 2 to 30 mm and diameters of from 1 to 5 cm, characterized in that the formed part is produced by pressing at temperatures in the range from 500 to 1000 DEG C and pressures of from 0.5 to 10 bar, under a protective gas such as nitrogen, if required, and without the addition of binders.

Abstract: The material is obtainable by a) reacting an aqueous dispersion of waterglass and a pigment with a strong acid and/or waterglass with a pigment-containing strong acid to give a pigment-containing silica hydrogel, the pigment being characterised in that it scatters, absorbs or reflects infrared radiation of wavelength 3 - 10 mu m, b) substantially freeing the pigment-containing silica hydrogel thus obtained from ionic constituents by washing out with water, c) displacing the water present in the hydrogel by means of a low- boiling liquid which is inert to the pigment-containing silica gel, d) heating the liquid-containing silica gel thus obtained with complete covering with the liquid to supercritical conditions and e) subsequently removing the liquid from the solid by flash evaporation at supercritical temperature.
