A treatment liquid composition for ink jet pigment printing is a treatment liquid composition which is used to be adhered to a cloth and which includes a block isocyanate compound, a hydroxyethyl cellulose, and a cationic compound.

The present disclosure is directed to marking compositions that are derived from environmentally friendly, biodegradable, and sustainable resources. Such compositions may be formulated in to writing and/or drawing instruments such as crayons. In various embodiments, the marking compositions include one or more of a structural component, a stiffening and/or laydown component, and a colorant. For instance, the structural component may be an ester wax composed of a diol and diacid, such as where the diols and diacids contain about 2 to about 14 carbon atoms each, such as where the structural component is present in an amount of from about 10% by weight to about 90% by weight, such as about 20% to about 80%, including about 60% of the composition. Additionally, the stiffening and/or lay down component may be a bifunctional fatty acid, such as stearic acid, which may be included in the composition, such as a stiffening agent as well as to enhance smoothness of laydown. A typically useful amount that may be used ranges from about 20% or less to about 80% or more, such as about 40% to 60% or more by weight of the composition. Further, in various embodiments, a naturally occurring, organic colorant may be provided as part of the marking composition.

In a three-dimensional printing method example, a pre-treatment coating is formed on a part precursor by applying and drying, alternatingly: a polycation solution including a chloride ion and a polyanion solution including a sodium ion to form at least two layers. An ink is selectively deposited on the pre-treatment coating.

An oil-based ink composition for a writing instrument, comprising a dye, an organic solvent and a phenolic compound of the following general formula (1): ##STR00001##
wherein R is each independently hydrogen or an alkyl group having 1 to 5 carbon atoms, R.sub.1 is any of an alkyl group having 1 to 5 carbon atoms, a halogenated alkyl group having 1 to 5 carbon atoms, a phenyl group, a hydroxyphenyl group, and an alkyl group having 1 to 5 carbon atoms substituted by a hydroxyphenyl group, and R.sub.2 is any of a halogenated alkyl group having 1 to 5 carbon atoms, a phenyl group, a hydroxyphenyl group, and an alkyl group having 1 to 5 carbon atoms substituted by a hydroxyphenyl group. The oil-based ink composition for a writing instrument can form handwriting having excellent water resistance in which no bleeding occurs on written surfaces of various materials with a dye retaining color development.

The present invention relates to a system, which comprises: b) at least one first colour layer containing a dye and/or pigment, c) on the at least one first colour layer an effect layer containing at least one platelet-shaped effect pigment, wherein the at least one platelet- shaped effect pigment is composed of particles having an average length of 2 to 500 m, an average width of 2 to 500 m and an average thickness of at most 1 gm, and d) on the effect layer at least one second colour layer containing a dye and/or pigment, wherein each of the at least one first colour layer and of the at least one second colour layer contains a dye and/or pigment being no platelet-shaped effect pigment, wherein the at least one dye and/or at least one pigment included in the at least one first colour layer is different from the at least one dye and/or at least one pigment included in the at least one second colour layer, and wherein, at least if the at least one first colour layer has a sum of reflectance and scattering of less than 40%, the system further comprises: a) below the at least one first colour layer a lower layer containing a pigment and having a sum of reflectance and scattering of at least 40%.

An admixture including at least one copolymer having a backbone. The backbone including at least one electrically charged monomer. The at least one copolymer is a grafted copolymer having mean molecular weight within a range between 600 g/mol and 3000 g/mol on side chains of the grafted copolymer. An additive manufacturing ink, Filament of the additive manufacturing ink, and inkjet printing ink including the admixture.

The present disclosure provides an ink fluid set containing an aqueous pretreatment composition and an aqueous inkjet ink. This ink fluid set is particularly suitable for printing on offset coated media.

Polymeric block copolymer dispersants made by controlled radical polymerization are disclosed that include polyacrylate solubilizing segments and styrene-maleic anhydride particulate anchoring segments. Desirably, a large percentage of the maleic anhydride units are reacted with an aminic reactant of 4 to 30 carbon atoms with 2 to 10 nitrogen atoms wherein at least one nitrogen is primary and the other is tertiary or three times bonded to carbon atoms.
