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.

Independent Claims | See all claims (32)

  1. 1. A substrate that contains a deodorizing ink, the deodorizing ink comprising from about 10 wt. % to about 50 wt. % carbonaceous particles and from about 5 wt. % to about 40 wt. % voided synthetic particles, wherein the voided synthetic particles have an average size less than the average size of the carbonaceous particles.
  2. 21. A nonwoven web that contains a deodorizing ink, the deodorizing ink comprising from about 10 wt. % to about 50 wt. % activated carbon particles and from about 5 wt. % to about 40 wt. % voided latex particles, wherein the carbonaceous particles have an average size of from about 5 to about 75 micrometers and the voided latex particles have an average size of about 5 micrometers or less.
