    Abstract: Process for the preparation of homopolymers or copolymers by homopolymerization or copolymerization of free-radically polymerizable water-soluble and/or water-dispersible monomers, optionally with further comonomers and optionally with at least one crosslinker, in an inverse emulsion polymerization in the presence of at least one redox initiator pair comprising an oxidizing agent and a reducing agent, where the reducing agent is 2-hydroxy-2-sulfinatoacetic acid and/or salt thereof; homopolymers or copolymers preparable by the process according to the invention, water-in-oil emulsions which comprise at least one homopolymer or copolymer according to the invention, solid compositions which comprise at least one homopolymer or copolymer according to the invention, the use of 2-hydroxy-2-sulfinatoacetic acid and/or salt thereof as reducing agent in a process for the preparation of homopolymers or copolymers; the use of the water-in-oil emulsion comprising at least one homopolymer or copolymer according to the invention for the thickening of aqueous solutions, and the use of 2-hydroxy-2-sulfinatoacetic acid and/or salt thereof as reducing component of a redox initiator pair comprising an oxidizing agent and a reducing agent for avoiding induction times during inverse emulsion polymerization.

    Abstract: A method for producing raised textures on a substrate by printing or coating with a composition containing a film-forming polymer binder, solvent and thermally-expandable polymer particles (I) etc. and then heating the coating, in which (I) comprises optionally colored, expandable polystyrene microspheres with a particle diameter (unexpanded) of 0.1-5 mm. An Independent claim is also included for printing compositions for textile printing and coating compositions for foam coating, containing 1-99.9 wt% of an aqueous dispersion of polymer binder, 0.1-99 wt% particles (I), 0-98.9 wt% additional water and 0-98.9 wt% additives such as foam suppressants, emulsifiers, thickeners, crosslinkers, pigments, pigment distributors, dispersants and fillers.

    Abstract: Polyurethane block copolymers with hydrophilic end groups are new. Polyurethane block copolymers (PBC) of formula (I)-(IV), are new. A-(B-A)n (I) A-B (II) A = a polyurethane block with at least one hydrophilic end group X ; B = a hydrophobic polyurethane block; X , X = hydrophilic end groups; and n = 1-20. Independent claims are also included for (1) a method for the production of crosslinkable dispersion binder systems by reacting these PBC with melamine derivatives of formula (V); (2) dispersion binder systems obtained by this method; (3) colorant preparations containing these binders plus water and finely divided inorganic or organic pigments; (4) ink for ink-jet printing, containing these pigment preparations; (5) a method for ink-jet printing on 2- or 3-dimensional substrates with this ink; (6) printed substrates obtained by this method; (7) high-solid paint systems containing the above binders; (8) solvent-based or water-based paint containing pigment preparations as in (3); (9) non-aqueous ink containing the above binders; (10) dye baths for pigment dyeing containing these dispersion binder additives; (11) a method for the production of such dye baths by stirring a pigment paste containing fine pigment and dispersion binder with water and optionally solvents, foam suppressants, feel improvers and/or biocidal agents and then filtering the mixture; (12) a method for dyeing substrates using binders or dye baths as above; (13) substrates dyed by this method; (14) printing paste for pigment printing containing the above dispersion binders; (15) a method for the production of such printing paste by stirring a rubbing paste (pigment plus dispersion binder) with water plus thickeners, fixing agents, feel improvers, emulsifiers and/or Bronsted acids; (16) a method for printing substrates using binders or pastes as above; and (17) substrates printed by this method. R -R = H, -CH2OR , -CH(OR )2 or -CH2-N(R )2; R = H, 1-12C alkyl or alkoxyalkyl of formula -(CH2CH2O)m-H, -(CH(CH3)CH2O)m-H, -(CH2CH(CH3)O)m-H or -(CH2CH2CH2CH2O)m-H; and m = 1-20.
