| 摘要 |
The invention relates to a novel, highly efficient tobacco smoke filter provided with mechanically (fibrous) and/or adsorptively filtering materials as well as chemosorptively filtering components, which comprises a synergistic composition containing at least one of a compound having a high nucleophilic additivity, capable of chemically reacting and stable adduct forming with excited and ground-level aldehydes not filtered out by the mechanically and/or adsorptively filtering materials; and at least one of a compound containing <IMAGE> enediol structural moieties, wherein the enediol type compound or its combination suitably amount to at least 50% by weight of the other chemosorptive components and 40 to 300% by weight of the adsorptively filtering materials. |
