    Abstract: Electrostatic toners containing a polymeric binder and, as charge stabiliser, a polyamine whose mean molecular weight is from 150 to 15000, where the nitrogen atoms are separated from one another by optionally substituted C1-C13-alkylene or optionally substituted phenylene and carry, as substituents, optionally substituted C1-C13-alkyl, phenyl, C1-C10-alkanoyl, benzoyl, C1-C6-alkylcarbamoyl, phenylcarbamoyl or a radical of the formula CO-L-CO, in which L is C2-C8-alkylene, crosslinking of two polyamine units resulting in the latter case, and the use of the abovementioned polyamines as charge stabilisers in electrostatic toners.

    Abstract: Photopolymerisable recording material contains at least one photopolymerisable, olefinically unsatd. organic cpd. (1), opt. a polymeric binder (II), at least one photopolymerisation initiator (III), a colour forming system (IV) which on irradiation with actinic radiation causes an increase in the colour intensity of the recording material, a sensitiser (V) and opt. further additives and/or assistants. (V) comprises at least one cpd. of formula (V) or (VI) in which X = CH or N; Y = H, 1-12 C alkyl, 1-12 C alkoxy or halogen; R1 = 1-12 C alkyl, 1-12 C alkoxy, or halogen; R1 = 1-12 C alkyl, 1-12 C alkoxy, CF3, phenyl or NR4R5 (in which R4 and R5 = 1-6 C alkyl, allyl, phen-C1-4alkyl, phenyl, etc.); and R2 and R3 = 1-12 C alkyl, 1-12 C alkoxy, hydroxy-C1-4alkyl, oxaalkyl with 2-12 C and 1-5 O atoms, phen-C1-4alkyl, phenyl, naphthyl, aryl susbtd. b y 1-4 C alkyl, 1-4 C alkoxy, phenyl, CF3, trialkylsilyl, CN, -O-CO-C1-12alkyl, -CO-O-C1-12alkyl, etc.. The long wave absorption max. of cpd. (V) is below 420 nm, pref. below 400 nm.

    Abstract: Polyethyleneimine-containing azo dyes of the formula [(D-N=N-K-)yX-]mP where D is the radical of a diazo component which is derived from an isocyclic aromatic amine or from a heteroaromatic amine and is free of hydroxysulfonyl groups, K is the radical of a coupling component of the hydroxynaphthalene, aminopyridine or pyrazolone series which has at most one hydroxysulfonyl group, or is the radical of a coupling component derived from acetoacetic acid, y is 1 or 2, X is a covalent bond or a bridge member if y is 1 or a bridge member if y is 2, and P is the radical of a polyethyleneimine whose degree of polymerization n is from 5 to 25000, and the number m of chromophore radicals is dependent upon the degree of polymerization n and is defined by the ratio m:n=from 1:1 to 1:35, with the proviso that when K is substituted by hydroxysulfonyl the ratio m:n is from 1:2 to 1:35, are useful for dyeing or printing fiber materials and for preparing inks for the ink jet process.

    Abstract: An electrostatic toner contains a polymeric binder and as a charge stabilizer a polyamine whose average molecular weight is from 150 to 15,000 and wherein the nitrogen atoms are separated from each other by C1-C13- alkylene, which may be phenyl-substituted, or by phenylene, which may be C1-C4-alkyl-substituted, and are substituted by C1-C13-alkyl, which may be phenyl-, hydroxyl- or carboxyl-substituted, phenyl, C1-C10-alkanoyl, benzoyl, C1- C6- alkylcarbamoyl, phenylcarbamoyl or a radical of the formula CO-L-CO, where L is C2-C8-alkylene, the last case resulting in the crosslinking of two polyamine units.
