KONDENSATIONSPRODUKTE AUF BASIS VON KOLOPHONIUM

Condensation products based on rosin, obtainable by A) reaction of 100 parts by weight of rosin (component I) 10-150 parts by weight of an aromatic mono- or dihydroxy compound substituted in the p position by C1-C12-alkyl (component II) and 3-50 parts by weight of formaldehyde or a compound providing formaldehyde (component III) at 50-250 DEG C in the presence of a base, it also being possible initially to prepare from components II and III a precondensate (resol) with an average degree of condensation of 2 to 20, which is then reacted with component I, B) further reaction of the condensation product (A) formed in stage A, at 150-250 DEG C with 4-40 parts by weight of an alpha , beta -unsaturated C3- or C4-mono- or dicarboxylic acid or with maleic anhydride (component IV) and C1) reaction of the adduct (B) formed in stage B), at 100-200 DEG C with 3-100 parts by weight of an at least monounsaturated aliphatic monofunctional or bifunctional alcohol or amine or of an at least monounsaturated C2-C12-amino alcohol (component V) or C2) reaction of (B) with 2-30 parts by weight of a C2-C4-alkylene oxide or of a C2-C12-alkanediol or amino alcohol (component VI) at 100-200 DEG C and then with 10-100 parts by weight of an at least monounsaturated C8-C40-fatty acid (component VII) at 150-250 DEG C, with the proviso that the molar amount of component (VII) is 0.2-1 mole per mole of (VI), or obtainable by D) reaction of 100 parts by weight of rosin (I) with 5-40 parts by weight of component (IV) at 150-250 DEG C, E) reaction of the adduct (D) obtained in stage D, at 100-200 DEG C with 2-30 parts by weight of a C2-C12-amino alcohol (VIa), F) further reaction of the product (E) obtained in stage E, at 50-250 DEG C with 10-150 parts by weight of component II and 3-50 parts by weight of component III in the presence of a base or with 10-200 parts by weight of a resol previously formed from components II and III, which has an average degree of condensation of 2 to 20 and G) reaction of the condensation product (F) obtained in stage F, at 150-250 DEG C with 10-100 parts by weight of component VII in the molar ratios of (VII):(VI) specified in (C2). These condensation products are suitable as binders for printing pastes.
