    Abstract: Pyrazole derivs. of formula (I) and their acceptable salts are new: (R1 = 6-membered aromatic heterocyclyl with 1 or 2 N atoms opt. substd. by 1-3 halo and/or one 1-4 C alkyl). Prepn. comprises reacting corresp. 4-aminophenyl cpd. with X. CO. R1 (X = OH, halo or alkoxy) under usual conditions, then opt. converting to a salt. (I) have antiphlogistic activity and very low toxicity. The ED33 for inhibition of carragheenin (0.1 ml; 10 mg/ml) induced oedema in the rat paw is 10.9 mg/kg for 1-phenyl-5-(4-nicotinoylaminophenyl)pyrazole (Ia) c.f. 9.5 mg/kg for phenylbutazone. However, phenylbutazone has LD50 (p.o., mouse) 815 mg/kg, whereas (Ia) caused no deaths at 4640 mg/kg. The specifically claimed (Ia) was prepd. in 76% yield by reacting nicotinoyl chloride with 1-phenyl-5-(4-aminophenyl)pyrazole in presence of Et3N in toluene.

    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.
