.~.~> Continuous phase contains organic material {2}
DEFINITION
Classification: 149/17
(under subclass 2) Product containing particulate material dispersed substantially entirely within a solidified or matrix medium and which products are characterized by dispersed phase within a continuous phase.
(1) Note. See part "(2)" of the definition of subclass 2
and see also "(1)" Note", f. of the class definition.
(2) Note. The product for this and indented subclasses is usually obtained by (a) forming a dispersion of particles (and maintaining them as such) in a liquid followed by solidifying the liquid to yield a homogeneous two phase mass or by melting at least one phase of a solid multiphase system followed by solidifying, e.g., freezing, setting, curing, solvent removal, etc., or (b) similarly forming a homogeneous two phase mass by mixing at least two liquids having different solidification temperatures, the first to solidify being formed into granules and dispersed in the last liquid to solidify the latter serving as the matrix and (c) milling or kneading a plastic, stiff paste or dough material containing a particulate material to form a two phase homogeneous mass. Excluded however, are those products or compositions wherein the "particulate material" is a filler, color, dye or similarly nonexplosive material. For the purpose of this and indented subclasses the presence of at least 10% of the matrix-phase material is arbitrariconsidered to be a sufficient quantity to inherently form the matrix in continuous phase unless the patent specifically teaches to the contrary.
(3) Note. Patents are not classified within this and indented subclasses which involve merely the addition of a liquid to particulate material where the latter serves as a carrier or adsorbent for the liquid (even though the liquid is said to be a binder) where such liquid is, for example, either fugitive, remains as liquid or evaporates leaving a solid particulate residue.
