Abstract: The present invention relates to an aqueous pigment dispersion containing a bisacetoacetarylide pigment (A), a dispersant (B), and an aqueous medium (C) and having an absorbance ratio represented by (absorbance at a wavelength of 408 nm)/(absorbance at a wavelength of 450 nm) of 1.40 or more and to an inkjet ink containing the aqueous pigment dispersion.

Abstract: [Object] To provide a water-based pigment dispersion for an inkjet recording water-based ink with which color recording images excellent, in terms of color development property, light resistance, and ejection durability are obtained; such an inkjet recording water-based ink; and a water-based ink set including such a water-based ink and a polyvalent metal salt solution. [Solving Means] A water-based pigment dispersion for an inkjet recording water-based ink and an inkjet recording water-based ink includes an organic pigment (A) and an anionic-group-containing organic polymer compound (B) in a water-based medium (C), wherein, as the water-based pigment dispersion, a water-based pigment dispersion in which the organic pigment (A) is a red pigment composed of a disubstituted quinacridone and a water-based pigment dispersion in which the organic pigment (A) is C. I. Pigment Red 269 are used in combination.

Abstract: In a press-forming method, a plurality of plates are prepared and end faces of the plurality of plates are butt joined to obtain a blank having joined portions. The blank has deformed-shape sections formed in a vicinity of the joined portion so as to deform in a direction along which peripheral lengths of the deformed-shape sections are stretched. Press-forming, involving stretch-flange formation, is carried out on the blank so as to allow the joined portions to be included in stretching regions, respectively. Also, the stretch-flange formation is carried out on the blank while restraining ends of the joined portion of the blank.
