Abstract: A coated paperboard (100) comprising: a base substrate (102) having a brightness of about 65 or less measured using TAPPI T452 and a coating (104) on at least one side of the base substrate, wherein the base substrate comprises: one or more opaque layers (114) including a white filler, wherein the opaque layer covers the base substrate so that visibility of the base substrate through the opaque layer is substantially eliminated; a barrier layer (116) covering the opaque layer; wherein the barrier layer substantially prevents aqueous fluids from contacting the opaque layer, and wherein the coated paperboard has a brightness on the side of the base substrate with the coating of about 65 or more measured using TAPPI T452, and a wet brightness drop, on the side of the base substrate with the coating, of about 30 or less, measured using the wet brightness drop test.
