A color material dispersion liquid comprising: (A) a color material, (B) a dispersant and (C) a solvent, wherein the color material (A) contains a lake color material of a combination of an acid dye and a polyaluminum chloride; a basicity of the polyaluminum chloride is 70% or more; and a value of a ratio (I.sub.4/I.sub.6) between an integral value (I.sub.4) of a peak corresponding to a four-coordinate aluminum in a solid-state .sup.27Al-NMR spectrum of the lake color material and an integral value (I.sub.6) a peak corresponding to a six-coordinate aluminum therein, is from 0 to 0.50.

A formulation of Atrorosins, and Atrorosin Lakes. Additionally, methods for their production by binding to inert metallic mordant is provided; and further the uses of the lakes as a coloring agent for food items and/or non-food items, and for cosmetics.

The present invention aims to provide colored foods that retain their inherent good flavors and which yet feature suppressed fading of dyes. Provided are colored foods that contain rosmarinic acid and which are reduced in the contents of luteolin-3-glucuronide, carnosic acid, and carnosol.

The present invention relates to an inorganic-organic hybrid compound as ionic compound, composed of an inorganic cation and of an organic active ingredient anion and also, optionally, of an organic fluorescent dye anion.

The present invention relates to a method of preparing a colored gloss pigment using a natural dye. According to the present disclosure, the method may include preparing a dye from a dye material of natural dyes; titrating the dye with an inorganic salt solution and subsequently adjusting a pH neutral to prepare a natural pigment containing the dye; dispersing a substrate coated with a metal oxide into a DI water to form a substrate suspension; and introducing a pH adjusting agent and the natural pigment into the substrate suspension to coat a surface of the substrate with the natural pigment.
