Claim 3

A phenol-novolak according to claim 1, of the formula VI or VII, in which the radicals R 1 are each alkyl having not more than 4 C atoms, the radicals R 3 are each a hydrogen atom, the radicals R 2 are each a hydrogen atom, phenyl or alkyl having 1 to 4 C atoms, the radicals R 4 and R 5 independently of one another are each linear or branched alkyl having not more than 4 C atoms and x has an average value from 1 to 8.

Claim 4

A process for preparing a phenol-novolak, containing amino groups, having the formula VI or VII ##STR12## in which R 1 is bonded in the o- or p-position relative to the phenolic OH group and is a halogen atom, a nitro group, linear or branched alkyl having not more than 6 C atoms, alkoxy having not more than 6 C atoms or phenyl, R 2 is a hydrogen atom, linear or branched alkyl having not more than 8 C atoms, cycloalkyl having 5 or 6 C atoms, phenyl or furfuryl, R 3 is hydrogen atom or linear or branched alkyl having not more than 8 C atoms, R 4 and R 5 independently of one another are each linear or branched alkyl which has not more than 6 C atoms in the alkyl radical and is unsubstituted or substituted by halogen atoms, nitro or cyano groups or alkoxy having not more than 4 C atoms, or a halogen atom or a nitro or cyano group, and x has an average value from 1 to 8, which comprises reacting, in an aqueous, acid medium at a pH value of 0.5 to 3, a phenol-novolak of formula V ##STR13## with an aldehyde or ketone of formula II ##STR14## and with a substituted aniline of formula III or IV ##STR15## wherein R 1 , R 2 , R 3 , R 4 and x are as defined above, in a molar ratio of 1 mol of phenol-novolak of formula V to 2 mols of an aldehyde or ketone of formula II and 1 to 2 mols of a substituted aniline of formula III or IV.
