A multi-layered coating for use preferably on paperboard or paper is disclosed wherein the coating contains at least two layers. The first layer contains at least one dark colorant, at least one white or near white pigment, and at least one binder, and the second layer contains at least one pigment other than a dark colorant, such as a white or near white pigment, and at least one binder. Slurries and dry mixtures containing these ingredients are also disclosed. A multi-layered coated paperboard or paper comprising paperboard or paper and the multi-layered coating is also disclosed. A method to reduce the amount of a white or near white pigment like titania is also disclosed which involves using one or more of the above-described multi-layered coatings on paperboard or paper.read more
