Abstract: The invention concerns binders containing: A) an aminotriazine derivative in which the triazine primary amino groups are methylolated on average with at least one mol of formaldehyde per mole of primary amino groups and these methylol groups are etherified on average with at least 0.5 mole primary alcohol per mole of methylol group, and the primary alcohols are a mixture containing: a) 0.5 to 99.5 mol % of a C1-C4 alkanol and b) 99.5 to 0.5 mol % of an alcohol of the formula (I) R -O-[R -O]n-R -OH, in which R stands for a C1-C24 alkyl group or a C6-C12 aryl group which may optionally be substituted by one to three C1-C8 alkyl groups, and R and R , independently of each other, stand for a C2-C8 alkylene group, and n means an integer from 1 to 100, or a mixture of higher-boiling alcohols having a boiling point of more than 120 DEG C at 1 bar, which contains at least 10 mol %, relative to the higher-boiling alcohols, of alcohols of formula I; and B) a radical polymer, which can be crosslinked with the aminotriazine derivative, a polycondensate or polymer additive.

Abstract: Polyester resins on the basis of hydroxyl groups-containing prepolymers from olefinically unsaturated monomers are prepared by (1) polymerizing a mixture of (a) 60 to 90% by weight styrol or a styrol derivate having the general formula (I), in which R , R and R stand for hydrogen, methyl or ethyl and n equals 1 or 2, or a C2-C10-olefin with one or two conjugated double bonds, or a mixture thereof; (b) 0 to 40% by weight C1-C12-alkylester of acrylic or methacrylic acid, acryl- or methacryl-nitril, acryl-or methacrylamide, which may be substituted at the amide-nitrogen by one or two C1-C4-alkyl groups, maleic anhydride or maleic acid imide, which may be substituted at the imide-nitrogen by a C1-C4-alkyl group, or a mixture thereof; (c) 0 to 20% by weight one or several hydroxyl group-containing acrylic or methacrylic acid derivates; and (d) 0 to 2% by weight one or several olefinically poly-unsaturated monomers; to obtain a prepolymer A, into which the hydroxyl groups are inserted by means of hydroxyl groups-containing regulators when the monomer component (c) is missing and by a mixture of (A) 5 to (95% by weight prepolymer A; (B) 0 to 95% by weight another low molecular or high molecular polyol, a polyester or a polyamid, or a mixture thereof; and (C) 5 to 70% by weight one or several aliphatic or aromatic dicarboxylic acids C or their C1-C4-alkylesters. Carboxylic acids or their C1-C4-alkylesters having more than two carboxyl groups per molecule, monocarboxylic acids or their C1-C4 alkylesters, hydroxymonocarboxylic acids or their C1-C4-alkylesters or mixtures thereof, as well as waxes may also be present during polycondensation. These polyester resins are suitable as binders for electrophotographic toners and for the receiving layers in the thermodiffusion printing method.
