DEFINITION

Classification: 516/100

The organic material coats, impregnates, or surface modifies solid inorganic material (e.g., dextrin modified clay):

(under subclass 99) Subject matter in which the organic* material* coats, impregnates, or surfaced modifies an inorganic* material*.

98, for colloid systems of continuous or semicontinuous solid phase which does not have organic* material* in the solid phase, and also is of a solid material* not provided for in subclasses 110, 111, or 112.

110, for colloid systems of continuous or semicontinuous solid phase in which the solid phase contains metal silicate or clay and which does not have organic* material* in the solid phase.

111, for colloid systems of continuous or semicontinuous solid phase in which the solid phase contains silica and which does not have organic* material* in the solid phase.

112, for colloid systems of continuous or semicontinuous solid phase in which the solid phase contains alumina and which does not have organic* material* in the solid phase.
