Zusammenfassung:	Resins having a softening point of from 50 DEG to 130 DEG C., an OH-number of from 250 to 400 and an iodine number of from 90 to 160, obtainable by reacting an alkyl phenol-formaldehyde novolak or an alkyl phenol mixture-formaldehyde novolak under acid-catalysed conditions with a polunuclear phenol or polynuclear phenol mixture and formaldehyde and/or an aliphatic aldehyde or aliphatic aldehyde mixture, the ratio by weight of the alkyl phenol or alkyl phenol mixture to the polynuclear phenol or polynyclear phenol mixture being from 2.2:1 to 1:10.
