DEFINITION

Classification: 508/147

With azo compound, inorganic phosphorus salt, or oxidate of undetermined composition as additional component or surface-treating agent:

(under subclass 136) Compositions which contain, in addition to the silicon dioxide, silicic acid, orthosilicate, or metasilicate, an azo compound, an inorganic compound that is a phosphorus salt, or an oxidate of indeterminate composition; the azo compound, inorganic compound, or oxidate may be present as an additional component or as a surface-treating agent for the silicon dioxide, silicic acid, orthosilicate, or metasilicate.

(1) Note. An azo compound is an organic compound characterized by the group -N=N- wherein both nitrogens are acyclic and each is bonded directly to carbon.

(2) Note. See Notes to the Class Definition for the definition of an organic compound.
