    摘要： PROBLEM TO BE SOLVED: To provide an aromatic diamine-containing polymer compound which has high solvent solubility and exhibits excellent preservability when used as ink and from which an element excellent in a driving voltage, service life when driven and luminescent efficiency can be obtained. SOLUTION: The polymer compound has 3,000-27,000 weight-average molecular weight and has a repeating unit shown by formula (1) (wherein Ar 1 -Ar 5 are each an aromatic hydrocarbon group or a heteroaromatic group each of which can have a substituted group; X is a linking group).

    摘要： PROBLEM TO BE SOLVED: To obtain a color toner excellent in durability and environmental stability and excellent also in transparency by forming acicular crystals having a specified minor axis size to major axis size ratio and a specified minor axis size and incorporating a specified compd. or its metallic compd. SOLUTION: The toner is acicular crystals having a minor axis size (b) to major axis size (a) ratio (b/a) of , the ring A , R and R is the residue of an arom. ring which may have a substituent and R is a divalent org. group. The metallic compd. may be a partial potassium salt of the compd. of formula I or II and the potassium content is 0.001-0.5 mol, preferably 0.001-0.3 mol, further preferably 0.001-0.1 mol per mol of the compd.

    摘要： PROBLEM TO BE SOLVED: To improve moisture, light and heat resistances by using a specified partial potassium salt having a specified potassium content. SOLUTION: The electrostatic charge controlling agent is a partial potassium salt of a compd. represented by formula I or II and the potassium content is 0.001-0.5 mol per 1 mol of the compd. represented by the formula I or II. In the formula I, each of A and R is the residue of an arom. ring which may have a substituent and -OH and -CONH-R bond to adjacent substitution positions on the residue A. In the formula II, each of A , A , R and R is the residue of an arom. ring which may have a substituent, (n) is a natural number, and -OH and -CONH-R , and -OH and -CONH-R bond to adjacent substitution positions on the residues A and A , respectively. The electrostatic charge controlling agent, optionally together with a resin binder, is dissolved in a solvent or dispersed in a dispersive medium to prepare a coating soln.
