Abstract: The aqueous pigment dispersion for IJ inks has excellent dispersion quality as well as high color strength and light fastness and is particularly suited for use as an U aqueous pigment ink. It includes C.I. Pigment Yellow 180, a block copolymer having an acid value of 10 or more and 20 or less and an amine value of 20 or less, and water. The present invention also provides C.I. Pigment Yellow 180 having an aspect ratio of 1.0 to 2.0, a primary particle shorter diameter of 30 to 100 nm, and a crystallite size of 15.0 nm or more as calculated from the Scherrer equation based on the full width at half maximum of a peak A indicated by a maximum diffraction intensity at a diffraction angle 2?=6.7±0.50 in a powder X-ray diffraction pattern of diffraction intensities versus 2? measured using CuK? radiation.

Abstract: A woven and knitted fabric according to an embodiment of the present invention includes a yarn containing elastic fibers and at least one kind of non-elastic fibers. The woven and knitted fabric is subjected to mold processing. The elastic fibers contain heat-fusible polyurethane elastic filaments each having a fineness of 17 dtex or more, and at least part of the heat-fusible polyurethane elastic filaments is heat-fused in the woven and knitted fabric. The woven and knitted fabric is subjected to the mold processing at 120 to 190° C.

Abstract: The present invention provides a woven and knitted fabric, which prevents sliding and slipping of garments and the like, has excellent wearing feeling, and has excellent shape stability and durability. The woven and knitted fabric of the present invention includes constituent fibers containing 50% or more of polyurethane elastic fibers, the polyurethane elastic fibers containing 40% or more of heat-fusible polyurethane elastic fibers. The woven and knitted fabric has heat-fusion parts in which the heat-fusible polyurethane elastic fibers are heat-fused.
