Whenever in groups C09C 1/00 - C09C 1/66 the materials consist of a particulate core bearing a coating or any other deposit, classification is done only according to the composition of the core, unless otherwise stated, e.g. C09C 1/0015, C09C 1/0078. Preparations of materials which are no single chemical compounds, mainly comprising ceramic pigments (C09C 1/0009), consisting of solid solutions or polycrystalline structures, and compounds defined as composite materials (C09C 1/0081). Preparation and treatment steps are not always easy to distinguish from each other, e.g. preparation in the presence of treating agents (by precipitation or calcination), precise reacting conditions, affecting pigmentary effects. It is common practice to include these complex topics in C09C 1/00 while avoiding redundancy.
The last appropriate place rule applies.
When classifying in this subclass, symbols of C01P are used to identify structural or physical aspects of solid inorganic compounds.
In case a group is indicated as indexed, the subgroups thereof are also indexed.
The symbols of C01P group deals with Structural and Physical Aspects of Solid Inorganic Compounds classified in subclasses C01B - C01G and C09C. These aspects include crystal-structural characteristics, particle morphology and physical properties.
Exception from the last appropriate place rule:
Dopant: A dopant, also called a doping agent, is a trace impurity element that is inserted into a substance (in very low concentrations) in order to alter the physical properties of the substance. For the purpose of classification, a dopant is considered as such, when its concentration is less than 5% (wt, vol, at.) or when mentioned as such in the patent document to be classified.
In such a case, the compound is classified ignoring the dopant(s) and the last appropriate place rule does not apply in view of the dopant(s). In case of doubts, the document is given the classification symbol relating to the last appropriate place rule by taking into account the dopant(s) and in the appropriate class, without taking into account the dopant(s).

In this place, the following terms or expressions are used with the meaning indicated:
Pigment | A material that changes the color of reflected or transmitted light as the result of wavelength-selective absorption. This physical process differs from fluorescence, phosphorescence, and other forms of luminescence, in which a material emits light. A distinction is usually made between a pigment (inorganic), which is insoluble in the vehicle (resulting in a suspension), and a dye (organic), which either is itself a liquid or is soluble in its vehicle (resulting in a solution). |

Pigments with interference colours, e.g. pearlescent pigments, interference pigments, luster pigments, optical variable pigments (OVP), effect pigments.
In general interference pigments consist of one substrate coated with one or more optically active layers. The optical active layers have a high or low refractive indices. A comprehensive list of inorganic compounds and their refractive indices can be found in "Sample dispersion & refractive index guide", Malvern Instruments Ltd. 1997.
Protective layers or functional layers applied on said interference pigments consist in general of metal oxides, silica, fatty acids, polymers, silanes etc. and are deemed not to affect the optical properties of the core pigment on which they are applied. Therefore and for the purpose of classification this layers are considered as being not optically active.
A rutilisation promoting layer (mostly SnO2) is also not considered as being optically active if not otherwise stated. Also, other layers, like adhesion promoting layers etc., are also considered as optically not active.

Lithopone is an insoluble mixture of barium sulfate and zinc sulfide that precipitates upon mixing solutions of barium sulfide and zinc sulfate. The precipitate is recovered by filtration, then calcined (roasted) at temperatures above 600° C (1,112° F). Although lithopone has been replaced in many applications by titanium dioxide, introduced after World War I, it is still widely used in a number of products, such as water paints.

Ultramarine is a blue pigment consisting primarily of a double silicate of aluminium (three dimensional aluminosilicate lattice) and sodium with some sulfides or sulfates, and occurring in nature as a proximate component of lapis lazuli. In the past, it has also been known as azzurrum ultramarine, azzurrum transmarinum, azzuro oltramarino, azur d'Acre, pierre d'azur, Lazurstein. Current terminology for ultramarine include natural ultramarine (English), outremer lapis (French), Ultramarin echt (German), oltremare genuino (Italian), and ultramarino verdadero (Spanish). Ultramarine is a complex sulfur-containing sodium-silicate (Na6-10Al6Si6O24S2-4) containing a blue cubic mineral called lazurite (the major component in lapis lazuli). The blue color of the pigment is due to the S3− radical anion, which contains an unpaired electron.
