    Abstract: PCT No. PCT/EP95/04576 Sec. 371 Date May 23, 1997 Sec. 102(e) Date May 23, 1997 PCT Filed Nov. 21, 1995 PCT Pub. No. WO96/02597 PCT Pub. Date Feb. 1, 1996A process for coating or printing substrates with a coating or printing composition comprises applying a polymerizable material containing liquid-crystalline, polymerizable monomers which carry at least two polymerizable groups for coating and at least one polymerizable group for printing, to the substrate, and subsequently carrying out the polymerization, where the coating composition or the printing composition comprises a1) a chiral liquid-crystalline monomer and b) a polymeric binder and/or monomeric compounds which can be converted into the polymeric binder by polymerization, or, in the case of emulsion coatings and printing inks, a dispersion auxiliary d), or the coating composition or the printing composition comprises a2) an achiral liquid-crystalline monomer, b) a polymeric binder and/or monomeric compounds which can be converted into the polymeric binder by polymerization, or, in the case of emulsion coatings and printing inks, a dispersion auxiliary d), and c) a non-liquid-crystalline chiral compound.

    Abstract: Preparation of low-temperature-stable alkanolic-aqueous solutions of polyethersulphonates of the general formula I R-(O-A)n-SO3M I in which R represents an alkyl or alkenyl group having 8 to 25 carbon atoms or an alkylphenyl group having 8 to 18 carbon atoms in the alkyl radical, A denotes a 1,2-alkylene group having 2 to 4 carbon atoms, n has a value of between 1 and 15 and M represents an alkali metal cation or an ammonium cation which can be substituted by C1-C4-alkyl groups or C1-C4-hydroxyalkyl groups, by reacting polyether halides of the general formula II R-(O-A)n-X II in which X represents chlorine or bromine, with an aqueous solution of an alkali metal sulphite or ammonium sulphite and diluting the reaction solution with a C4-C8-alkanol, by heating the reaction mixture after the reaction to 60 to 150 DEG C at 1 to 5 bar and separating the mainly aqueous phase which is formed in this process. The low-temperature-stable solutions of the polyethersulphonates I are used as surfactant solutions in tertiary oil drilling.
