Prepn. of light coloured terpene phenol comrpises reaction of terpene hydrocarbons with phenols in the presence of 5-20 wt. % (w.r.t. the terpene) of a strongly acid completely dry cation exchange resin or a dry bleaching earth as catalyst, at 50-100 degrees C. The catalyst is used in the presence of 0.01-5 wt. % (w.r.t. the terpene) of an antioxidant having the formulae (I) (II) or (III); after the reaction the catalyst is removed from the reaction mixt. which is then steam distilled to remove unreacted starting materials. (In (I), (II) and (III) n= 1,2, 3 or 4; R= 1-4C alkyl; R1, R2 and R5= H, 1-4C alkyl; R3 = 1-6C alkyl; R4= a 1, 2,3 or 4 valent 1-30C alcohol radicle; R6=H, 1-6C alkyl. The terpene phenol resins obtd. are almost colorless and need no further treatment before use. They are useable as additives for e.g. oil lacquers, printing inks, polishes, adhesive bands, records. Also as stabilisers for rubbers, waxes etc. and esp. laminated glass films. Their iodine numbers are low e.g. a camphene based resin, 50% in toluene, has as iodine number of 1-2. The catalysts are re-useable.
