An ink set for ink jet printing for improving a wide range of color gamut and providing excellent fastness on ink jet printed materials. The ink set including a yellow ink having Color Index Disperse Yellow 65, a magenta ink having Color Index Disperse Red 362, and a cyan ink having Color Index Disperse Blue 60.

The invention relates to a molded cellulose body which includes a functional substance having low impregnation efficiency, to the use thereof and to a method for introducing functional substances of low impregnation efficiency into a molded cellulose body during its production and after the molding step.

A nonwoven wipe having a reversible sanitizer indicator for multiple uses and recharges is provided. The nonwoven wipe includes a cloth-like nonwoven fabric coated with a reversible color-changing ink formulation. During use, the nonwoven wipe is impregnated with a quaternary ammonium compound-based sanitizer. When the level of free quaternary ammonium compound falls below a threshold level, the color-changing ink formulation changes from a first color to a second color, indicating the need to recharge the wipe. When the nonwoven wipe is recharged with sanitizer solution, the color-changing ink formulation changes back to the first color.

A method of color-dyeing a lens for goggles and glasses, whereby the lens includes a polycarbonate substrate, the method including the steps of: providing a liquid mixture of components including at least one dye or pigment, suitable for color-dyeing polycarbonate and a dispersion medium, whereby the at least one dye or pigment is dispersed as colloids in the dispersion medium; immersing the substrate into the mixture such that the at least one dye or pigment is impregnated into the substrate; and withdrawing the substrate from the mixture. The method is characterized in that the dispersion medium includes a solvent for dissolving the at least one dye or pigment, whereby the solvent includes at least one member selected from the group including an organic alcohol, in particular an aromatic alcohol, in particular benzylic alcohol; a butyl acetate, and a methacrylate ester, in particular methyl methacrylate.

The present invention provides water-based ink and coating compositions comprising greater than 70 wt % natural materials. The ink and coating compositions of the present invention are suitable for printing on feminine care products, baby care products, and other personal care products.

An inkjet textile printing method includes: a step A of preparing a light-colored textile pretreated with a pretreatment solution; a step B of applying by inkjet a white ink composition containing a white pigment, a water-dispersible resin, and water, to the pretreated light-colored textile; and a step C of applying by inkjet a chromatic color ink composition containing a chromatic color pigment, a water-dispersible resin, and water, onto an ink layer formed by the application of the white ink composition, in which an application amount of the white ink composition per unit area in an application region of the white ink composition is 3.0 to 13.0 times relative to an application amount of the chromatic color ink composition per unit area in an application region of the chromatic color ink composition in terms of solid content mass ratio.

A color hazing or decoloring agent including at least one compound selected from compounds represented by formula (1) and compounds represented by formula (2), and used for color hazing or decoloring of a fabric printed or dyed with a disperse dye:
