The Brand Names hierarchy contains records for materials, processes, and objects having names that are under trademark protection, primarily those of use to the art conservation community. Relation to other hierarchies: Concepts in this hierarchy may not be linked with a hierarchical genus/species relationship to concepts in any other facet. If a brand name in this hierarchy is an example of a generic material, process, or other AAT concept in another facet, link it through Associative Relationships (e.g., "Fome-Cor (R)" 2803 example of "foamboard").
