Abstract:
The present invention pertains to a dye-based inkjet ink set with a lightfast cyan ink and, more particularly, to a dye-based inkjet ink set suitable for printing on fabrics, especially polyamide fabric. The present invention also pertains to a method for printing a polyamide fabric with the dye-based inkjet ink set, and a polyamide fabric so printed.
Abstract:
A process is disclosed for treating textile materials with selected amine oxides in order to change the aesthetics and/or make the materials more receptive to dyes. In particular, the treatment cause cellulosic materials, to become more cationic and thus more receptive to anionic dyes with or without stiffening. In a preferred embodiment, the process of the present invention is directed to treating fabrics containing cottons fibres but will work to a useful extent on wool, nylon and polyester. The process is carried out by contacting said fibers or fabric with the selected amine oxide compositions. The amine oxide compositions can be padded onto the fabric or printed onto the fabric. If printed onto the fabric according to a particular design, the design then becomes visible on the fabric once dyed.
Abstract:
A compound formula (1) and salts thereof, wherein: m is 1, 2, or 3; X is H or SO3H; R and R are each independently selected from optionally substituted alkyl and optionally substituted alkoxy; and R and R are each independently H, optionally substituted alkyl or optionally substituted aryl; provided that: (i) at least one of R and R carries and -OH group; and (ii) when X is H at least one of R and R is optionally substituted alkyl. The compounds are useful as dyes for ink jet printing inks.

Abstract:
Black-dyeing aqueous inks comprising 20 to 95 % by weight of at least one dye (A), together with 5 to 80 % by weight of at least one dye chosen from the group consisting of (B) and (C), based on the total weight of the dyes (A), (B) and (C) in the ink, and 1 to 40 % by weight of water-miscible organic solvent, based on the total weight of the ink, the dye (A) containing, as the colouring part of the molecule, one or more radicals of formula (I), (II), (III) or (IV) the dye (B) containing, as the colouring part of the molecule, one or more mono- or disazo radicals containing sulfo groups or one or more radicals of the formula (V), (VI), (VII) or (VIII) and the dye (C) containing, as the colouring part of the molecule, one or more mono- or disazo radicals containing sulfo groups or one or more radicals of the abovementioned formula (V), (VI), (VII) or (VIII) and one or more radicals of the abovementioned formula (I), (II), (III) or (IV), in which (G)0-2 is 0 to 2 identical or different substituents from the group consisting of substituted or unsubstituted amino, hydroxyl and nitro, L is substituted or unsubstituted amino, R is halogen, C1-C4alkyl, C1-C4alkoxy, C2-C4alkanoylamino, hydroxyl, carboxyl, nitro or cyano, (V)0-2 is 0 to 2 identical or different substituents from the group consisting of halogen, C1-C4alkyl, C1-C4alkoxy, beta -sulfatoethylsulfonyl and sulfo, (W)0-1 is an N-acyl radical, if any n is the number 0, 1, 2 or 3, m is the number 1, 2, or 3 and r and q are the number 0 or 1. The inks according to the invention are distinguished by good black shades without a change in shade in artificial light (metamerism) and an outstanding fastness to light.
Abstract:
The invention relates to a method for printing fibrous textile materials using the ink jet technique. The method is characterised in that said fibrous materials are printed with an aqueous ink which contains at least one acidic dye as described in claim no. 1 and has a viscosity of 1 to 40 mPa.s
Abstract:
A novel colorant compound is provided which is the addition product of an organic chromophore having at least one reactive hydroxyl or amine substituent, a polyisocyanate, and a carboxylic acid, sulfonic acid, or salt of either thereof. The polyisocyanate, added in a molar excess relative to the number of such reactive substituents, reacts with the reactive hydroxyl or amine groups to provide terminal isocyanate groups. Subsequently, the carboxylic acid or salt thereof, also added in an amount excessive in relation to the number of terminal isocyanate groups, reacts therewith to form urethane moieties on the colorant. Such a compound provides excellent ink compositions upon dilution and are very soluble within all the standard ink diluents. Furthermore, such colorants provide good jettability, waterfastness, washfastness, and the like, within ink-jet applications on various types of printing substrates. A method for producing such a colorant and specifically printed substrates colored therewith is also provided.
Abstract:
A cationic fibrous acetate salt of boehmite alumina obtainable by providing a slurry of water and basic aluminum acetate, stirring the slurry to ensure substantially complete mixing thereof, reacting the slurry in a vessel for a time, temperature, and stiring rate sufficient to produce a fibrous cationic acetate salt of boehmite alumina having a zeta potential of greater than about 25 and a weight ratio of aluminum to acetate of less than about 4. The cationic fibrous acetate salt of boehmite alumina can be used in processes for dying fibers and for treating waste streams.
