11. An absorbent article, comprising:
a liquid permeable top cover at a bodyfacing side of said article;
a generally liquid impermeable outer cover;
an absorbent structure disposed between said top cover and said outer cover;
an odor control agent disposed between said top cover and said absorbent structure in a pattern that is visible through said top cover, said odor control agent having a color that contrasts with a color of said bodyfacing side of said article such that a minimum contrast gray scale value of at least about 45 on a scale of 0-255 is defined between said odor control agent and said bodyfacing side; and
wherein said odor control agent is deposited in said pattern on an inner surface of said top cover and is distinguishable through said top cover from said bodyfacing side of said article against a contrasting colored background defined by an upper surface of said absorbent structure.
12. An absorbent article, comprising:
a liquid permeable top cover at a bodyfacing side of said article;
a generally liquid impermeable outer cover;
an absorbent structure disposed between said top cover and said outer cover;
an odor control agent disposed in a pattern that is visible from said bodyfacing side of said article, said odor control agent having a color that contrasts with a color of said bodyfacing side of said article such that a minimum contrast gray scale value of at least about 45 on a scale of 0-255 is defined between said odor control agent and said bodyfacing side; and
wherein said pattern of odor control agent is defined on a material layer of said absorbent structure and is visible through said top cover without substantial alteration of said pattern by said top cover, said pattern of odor control agent distinguishable against a contrasting colored background defined by an upper surface of said material layer.
13. An absorbent article, comprising a top cover defining a bodyfacing surface of said absorbent article and a material layer disposed beneath said top cover, an odor control agent deposited in a visible pattern between said top cover and said material layer of said article, said odor control agent comprising a color so as to present a distinguishable pattern against a contrasting colored background defined by said material layer, said distinguishable pattern of odor control agent and contrasting colored background disposed visibly beneath said top cover and discernible to the user through said top cover when viewed through said bodyfacing surface.
