    摘要: Are disclosed disazo compounds represented by the general formula (1): ##STR1## wherein A represents a phenylene or naphthylene group which may be optionally substituted; each of R.sup.1 and R.sup.2 represent independently a hydrogen atom, an alkyl group or a phenyl group which may be optionally substituted; and m is 1 or 2. The compounds are highly water-soluble and are stable to long term storage. Ink compositions comprising the compounds of the invention can produce a printed image with full depth of shade and are excellent in resistance to water.

    摘要: Europium compounds represented by the general formula (1) and water-base ink compositions containing the same: [wherein X is an optionally substituted aromatic or heterocyclic group: Y is a fluorohydrocarbon group having 1 to 10 carbon atoms: Z1 to Z3 are each independently a hydrophilicity-imparting group: R1 to R3 are each a direct bond or a divalent hydrocarbon or heterocyclic group which may be substituted: n1 to n3 are each independently an integer of 0 to 2: and m1 to m3 are each independently an integer of 1 to 3, with the proviso that all of n1to n3must not be 0]. The compounds and the ink compositions are excellent in stability and safety, and emit red light by irradiation with ultraviolet light though they are substantially invisible in the visible light region. Thus, they are useful for prints which are to be read by a system having a sensor reading function with the need for hidden letters or security markings.

    摘要: An electrophotographic toner containing a specific compound as the charge control agent is described. The electrophotographic toner according to the present invention have a sharper distribution of the amount of electrification and better moisture resistance and time stability than those of a toner wherein a conventional charge control agent is used. Therefore it can provide an image having a very high gradation and has a very high capability of repeatedly forming an image. Since the charge control agent, as such, is essentially colorless, a colorant can freely be selected according to a hue required of a color toner and the toner is not detrimental to the hue inherent in a dye and a pigment.
