Patent abstract
A substrate that contains a deodorizing ink is provided. The composition contains carbonaceous particles (e.g., activated carbon) for adsorbing one or more malodorous compounds to reduce odor. Because carbonaceous particles typically have a dark black color that is sometimes aesthetically displeasing to the user, the deodorizing ink of the present invention also contains voided synthetic particles that mask, at least to some extent, the darker carbonaceous particles. More specifically, the voids of the particles contain air, which can scatter or diffract light to create an opaque effect that may hide the black color of the carbonaceous particles. In this manner, the color presented to the user may be more aesthetically pleasing.
