    Abstract: Reaction prods. obtained by condensation of phenols or napthols with formaldehyde (releasing cpds.) are reacted in alkaline, acidic or neutral medium with (a) urea derivatives in which one H-atom of an NH2-grp. is replaced by a grp. of formula -CH-COOH (wherein R is H or C1-9 alkyl residue) or by aromatic grps. of formulae (wherein X is H or a first-order substituent); and (b) mononuclear aromatic carboxylic and/or sulphonic acids which may contain hydroxyl or amino grps., and/or aryloxy aliphatic and/or aliphatic polycarboxylic acids with up to 8 C-atoms which may contain hydroxyl grps. Products are used in manufacture of binders and printing inks.
