Abstract: Condensation products which are obtained by reaction of aromatic hydroxycarboxylic acids with formaldehyde in a first stage and by a subsequent condensation reaction of the products with phenol and/or phenol derivatives in the molar ratio 1:(0.8-21):(0.6-20) are suitable as fixing agents for basic dyestuffs in paper printing.

Abstract: A novel metal modified novolak resin is prepared. The metal modified novolak resin is an electron acceptor and is further characterized by its compatability with the surface properties of a paper substrate. The metal modified novolak resin comprises a reaction product of a novolak resin and a metal salt. The novolak resin is a reaction product of a mixture containing a para-substituted phenol selected from the group consisting of paraalkylphenols having alkyl groups of about 1 to about 12 carbon atoms, para-phenylphenol and mixtures thereof, salicylic acid and formaldehyde.The novel metal modified novolak resin is prepared by heating a mixture containing one or more para-substituted phenols, salicylic acid, formaldehyde and an acid catalyst for a period of time sufficient to substantially completely react the phenols, salicylic acid and formaldehyde to form a melted novolak resin. The melted novolak resin is mixed with a zinc salt in an inert atmosphere to form the metal modified novolak resin.

Abstract: A phenolic chelate resin comprising the three-dimensional product obtained by cross-linking a phenolic compound represented by the general formula (I): ##STR1## (wherein M is an alkali metal atom, an ammonium group, or a hydrogen atom, and R.sub.1 and R.sub.2, which may be the same or different, each is a hydrogen atom or an alkyl group having 1 to 3 carbon atoms) with a phenol and an aldehyde. The phenolic chelate resin selectively adsorbs ferric ion and/or cupric ion in an acidic aqueous solution at a pH of 3 and less.

Abstract: Polyepoxide resins are adducted with amines and the adducts are then reacted with cyclic dicarboxylic acid anhydrides. The resulting resinous products when salted with an amine are water soluble or water dispersible. The resinous solutions or dispersions can be formulated into coating compositions particularly useful for metal substrates.

Abstract: Novel phenolamine resins which are condensation products of hexamethylene tetramine with a phenol component such as an alkylphenol with 5 to 12 carbon atoms in the alkyl radical, styrene-alkylated phenol, cumylphenol, diphenylolpropane, hydroxybenzoic acid. The condensation reaction is conducted at a temperature ranging from 90.degree. to 180.degree. C.The products thus prepared are efficient stabilizing agents for rubbers and vulcanizates.
