Aspects of the present disclosure relate to color compositions and methods of making a printed layer using the color composition as well as an article that can include the printed layer.

A pigment comprising dyed crystalline cellulose particles comprising a crystalline cellulose core having a surface charge, optionally one or more polyelectrolyte layers with alternating charges adsorbed on top of each other on the crystalline cellulose core, the polyelectrolyte layer closest to the core having a charge opposite the surface charge of the core, and at least one organic dye having a charge is provided.

A storage phosphor panel can include an extruded inorganic storage phosphor layer including a thermoplastic polymer and an inorganic storage phosphor material, where the extruded inorganic storage phosphor panel has an image quality comparable to that of a traditional solvent coated inorganic storage phosphor screen. Further disclosed are certain exemplary method and/or apparatus embodiments that can provide inorganic storage phosphor panels including a selected blue dye that can improve resolution. Certain exemplary storage phosphor panels include inorganic storage phosphor material with specific extrudable blue dye (copper phthalocyanine) for resolution greater than 16 line pairs per mm. Certain exemplary storage phosphor panel embodiments include any non-needle storage phosphor panel with resolution greater than or equal to 19 line pairs per mm.

A problem to be solved by the present invention is to provide a coloring composition which contains a threne compound unlikely to be highly dispersed in glycol solvents used in color filter-preparing steps in recent years, which allows the threne compound to be highly dispersed in a glycol solvent, and which can be used without causing an undesirable influence such as a curing failure in a color filter-preparing step. The above problem is solved by providing a coloring composition containing a specific anthraquinone derivative, a threne compound, and a glycol organic solvent.

The present disclosure is drawn to aqueous pigment co-dispersions. The co-dispersions include self-dispersed pigment with a chemically modified surface; released surface moieties from the self-dispersing pigment; pigment powder having the released surface moieties associated with pigment powder surfaces; polymeric dispersant; and water.

Color changeable materials can be incorporated into adhesive materials while maintaining the efficacy and stability of the indicator. The indicators provide simple, reliable, and cost effective detection means for detecting ammonia and carbon dioxide, and may find use in applications such as food packaging and medical applications.

A task to be achieved by the present invention is to provide an aqueous pigment dispersion which can be used in the production of an ink having reduced coarse particles so that the ink exhibits excellent dispersibility of the pigment in the aqueous pigment dispersion and excellent storage stability on such a level that a change of the physical properties with time is unlikely to be caused. The present invention is directed to an aqueous pigment dispersion including: a pigment (A) including C.I. Pigment Orange 43(a) having a primary particle diameter of 150 nm or less; a pigment dispersing resin (B) including a radical polymerization polymer having an acid value of 80 to 150 mg KOH/g; and water (C).

Provided is a coloring composition capable of forming a cured film having desired spectral characteristics even for thin-film. In addition, provided are a cured film, a pattern forming method, a color filter, a solid-state imaging element, and an image display device. The coloring composition contains: a pigment A having a structure in which an aromatic ring group into which a group with an oxygen atom, a sulfur atom, or a nitrogen atom bonded to an aromatic ring is introduced is bonded to a diketopyrrolopyrrole skeleton; and a compound having a curable group. A content of the pigment A in a total solid content of the coloring composition is 40% by mass or more.

The present invention relates to an optical article, and an optical filter and an imaging device including the same. The optical article comprises: a near-infrared absorption glass substrate including a divalent copper ion as a chromatic ingredient; and a pigment dispersion layer formed on one surface or both surfaces of the near-infrared absorption glass substrate and having a near-infrared absorption pigment and an ultraviolet absorption pigment dispersed across the resin matrix thereof. Provided with a first and a second transmission cut-off region, the optical article has the advantage of allowing the fabrication of an excellent near-infrared cut-off filter that can effectively block light in near-infrared and ultraviolet bands and does not permit a difference in color sense with the change of incident angles.
