DEFINITION

Classification: 106/402

Lake containing:

(under subclass 401) Pigments which contain carbon compound dyes absorbed in or absorbed on particles of salts, inorganic hydroxides or other compounds, e.g., aluminum hydroxide, barium sulfate, etc.

(1) Note. See Class 260, Chemistry of Carbon Compounds, appropriate subclasses for compositions which contain definite chemical compounds of dyestuff or organic pigment compounds with metals. Carbon coloring compounds which are produced in the presence of a preformed substratum, wherein novelty is alleged to reside in the combination or in the amount, form, or nature of the substratum, are in this class (106); however, where the substratum is synthesized simultaneously with the carbon compound, the product belongs in Class 260.
