Abstract: A combined shipping and display box is provided which is formed from a one-piece blank of box-board material configured such that, when erected, the box will include bottom, front and rear walls as well as an opposed pair of side walls. The side walls are each formed from respective side panels having a central sub-panel and a pair of divider sub-panels extending in opposite directions from the central sub-panel. These divider sub-panels are inwardly foldable onto their respective central sub-panel along predetermined fold lines so as to not only be positioned in adjacent contact with the central sub-panel, but also to establish protruding interior dividers for the shipping/display box. When erected, therefore, the terminal edges of each respective pair of divider sub-panels will abut one another such that each of the interior dividers is paired with a similar interior divider associated with the opposite side wall.

Abstract: The invention is an aluminum flake pigment particle, surface treated transition metal or rare earth metal salt. The treated pigment particle has been found to be highly useful in water-borne coating compositions having a basic pH. The treated pigment particles experience significantly less hydrogen gassing in a high pH environment, and in water-borne coating compositions than untreated aluminum flake pigment particles. The treated pigment particles are also useful when combined with a pigment dispersant composition to further inhibit corrosion and gassing when the pigments are used in a coating composition.
