C03C25/00

Surface treatment of fibres or filaments made from glass, minerals or slags [2018.01]

Note(s) In groups C03C 25/24-C03C 25/48, the last place priority rule is applied, i.e. at each hierarchical level, in the absence of an indication to the contrary, classification is made in the last appropriate place.[2018.01]A coating composition, i.e. a mixture of two or more constituents, is classified in the last of groups C03C 25/24-C03C 25/42 that provides for at least one of these constituents.When classifying in groups C03C 25/24-C03C 25/42, any individual constituent, i.e. compound or ingredient of a coating composition, which is not identified by the classification according to Note (2), and which itself is determined to be novel and non-obvious, must also be classified in the last appropriate place in groups C03C 25/24-C03C 25/42.When classifying in groups C03C 25/24-C03C 25/42, any individual constituent of a coating composition which is not identified by the classification according to Note (2) or (3), and which is considered to represent information of interest for search, may also be classified in groups C03C 25/24-C03C 25/42. This can, for example, be the case when it is considered of interest to enable searching of coating compositions using a combination of classification symbols. Such non-obligatory classification should be given as "additional information".When classifying in groups C03C 25/1025-C03C 25/1095, the composition of the coatings must also be classified in one or more of groups C03C 25/24-C03C 25/54, according to Notes (1) to (4).When classifying in group C03C 25/48, any individual coating which itself is determined to be novel and non-obvious must also be classified in groups C03C 25/24-C03C 25/42, according to Notes (1) to (4).
