    Abstract: PROBLEM TO BE SOLVED: To easily obtain a novel chemical agent for marking well penetrating into a wood and to generate marked color reaction by an extremely small amt. of the marking substance to enable visual observation, by treating the wood with arylamine represented by a specific formula. SOLUTION: In a wood marking method, wood is treated with arylamine represented by formula I, wherein Ar is a group represented by formula II, R and R are mutually unrelated hydrogen, a C1 -C18 alkyl group which may be substituted, may be interrupted in a form of an ether functional group by 1-3 oxygen atoms or interrupted by 1-3 non-adjacent C1 -C4 alkylimino groups, C5 -C7 cycloalkyl, C3 -C18 alkenyl or phenyl which may be substituted, or R and R are a 5- or 6-membered saturated heterocylic group together with a nitrogen atom.

    Abstract: An electrostatic toner contains a polymeric binder and as a charge stabilizer a polyamine whose average molecular weight is from 150 to 15,000 and wherein the nitrogen atoms are separated from each other by C1-C13- alkylene, which may be phenyl-substituted, or by phenylene, which may be C1-C4-alkyl-substituted, and are substituted by C1-C13-alkyl, which may be phenyl-, hydroxyl- or carboxyl-substituted, phenyl, C1-C10-alkanoyl, benzoyl, C1- C6- alkylcarbamoyl, phenylcarbamoyl or a radical of the formula CO-L-CO, where L is C2-C8-alkylene, the last case resulting in the crosslinking of two polyamine units.

    Abstract: The invention concerns electrostatic toners containing a polymeric binder and, as charge stabilizer, a compound of formula (I) in which n is 2 to 6; Q is a 2- to 6-valent group derived from benzene, cyclohexane, naphthalene, triphenylene or perylene; X is a chemical bond, oxygen, sulphur, sulphonyl, carbonyl or a group of the formula O-CO, CO-O, NH-CO or CO-NH; L is a bridging member; R , R and R are C1-C4 alkyl or C5-C7 cycloalkyl, or R and R together are 1,4-butylene, 1,5-pentylene or 1,5-(3-oxapentylene), or the group (a) is the pyridinium or 3-carboxylpyridinium ion; and An is the anion equivalent. The invention also concerns the use of such compounds as charge stabilizers in electrostatic toners.
