Patent number: 6352563Abstract: A printed cloth in which a dye is deposited in dots on the cloth to form a desired printed pattern. Said dot deposition is formed in a length of 0.05 to 0.3 mm to the longitudinal direction of the fiber in single fiber unit of the yarn constituting said cloth. A fine printed pattern is deposited clearly in good reproducibility. The printed pattern can be formed by using the dyes of the three primary colors or of the three primary colors and black color. It is preferred that Dyes I , II and III having a perceived chromaticity index (a) and (b) defined in the color range [CIE 1976 (L, a, b) space] on the cloth within the following range are used as said dyes of three primary colors and DyeIV is used as said black dye.Type: GrantFiled: February 22, 2000Date of Patent: March 5, 2002Assignee: Kanebo, Ltd.Inventors: Kazuo Kusaki, Toshikazu Fuse, Tohru Morita, Toshihiko Ishihara, Kazuyoshi Morimoto, Kazuo Iwata, Michiyo Nishimura
