NOTE
-
In groups C03C 25/24 to C03C 25/40, organic coating compositions also cover mixtures of organic and inorganic compounds. A coating composition which cannot be completely classified in a single one of groups C03C 25/24 to C03C 25/40 should be classified in each relevant group, in accordance with the following rules: - Compositions containing only one macromolecular constituent and one or more conventional inorganic or non-macromolecular compounds, e.g. acids, solvents, are classified according to the macromolecular constituent only. - Compositions containing two or more macromolecular constituents and further conventional inorganic or non-macromolecular compounds are classified according to the macromolecular constituent present in the highest proportion. If, however, the other macromolecular constituents represent invention information, classification is also made for these constituents. - Compositions containing macromolecular constituents present in comparable proportions are classified according to these constituents. - If non-macromolecular compounds in the composition also represent invention information, C03C 25/38, for specific solvents, fillers, dyes or pigments, surfactants, biocides or the like in C03C 25/24 or subgroups.
