Abstract: A C.I. Pigment Yellow 74 as an insoluble azo pigment is provided. This C.I. Pigment Yellow 74 is crystalline particles. The ratio (26.6°/11.7°) of a diffraction intensity of a peak at 26.6° to a diffraction intensity of a peak at 11.7° in terms of Bragg angle (2?±0.2°) as measured by powder X-ray diffraction using CuK ?-radiation is 0.85 to 1.12, and the average primary particle size is 20 to 130 nm. The use of this C.I. Pigment Yellow 74 as a colorant in a coloring composition enables to provide the coloring composition with excellent dispersibility and good particle size stability and storage stability compared with conventional pigments. The use of this coloring composition enables the formation (recording) of images having excellent clarity and transparency of such high levels that have not been achievable by conventional technologies.

Abstract: Pigment compositions each contain an organic pigment and at least one compound selected from compounds represented by the following formula (II), respectively: A-N?N—CH(COCH3)—CONH-E, B—N?N—CH(COCH3)—CONH-E or C—N?N—CH(COCH3)—CONH-E, wherein A represents a substituted or unsubstituted phenyl group, B represents a substituted or unsubstituted ?-naphthyl group, C represents a substituted or unsubstituted ?-anthraquinonyl group, D represents a particular substituted aromatic group, and E represents a substituted or unsubstituted phenyl group, with a proviso that the compounds each have at least one substituent represented by —COOM or —SO3M in which M represents a hydrogen atom, metal atom, ammonium group, organic amine group or quaternary ammonium group. Colored compositions making use of the pigment compositions and color filters making use of the colored compositions are also disclosed.

Abstract: A carrier bag including a box member having a bottom plate and a plurality of side plates that extend from the outer-periphery of the bottom plate in a direction perpendicular to the plane of the bottom plate. The box member is defined with an opening which is always oriented in an upper-diagonal direction relative to a surface when the box member is positioned on the surface with either the bottom plate or one of the side plates being in contact therewith. Furthermore, the carrier bag is provided with a caster at each corner portion defined between the bottom plate and one of the side plates. The opening is covered with a fastenable and unfastenable cover. The carrier bag is thereby fabricated so as to allow articles to be put therein in downward and side directions in relation to the surface. Thus, the carrier bag provides a choice of storage space for each size and shape of article.
