  • Patent number: 7531471
    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.

  • Patent number: 7510988
    Abstract: In at least one embodiment, a particulate water-absorbing agent is provided which not only ensures the many conventional physical properties (absorption rate, centrifuge retention capacity, absorbency against pressure, particle size distribution etc.) but also prevents odor which is generated after the resin is swollen by absorption. The water absorbent agent of an embodiment of the present invention therefore does not cause odor in actual use. As a result of intensive study of the foregoing problem, an embodiment of the present invention offers a way of controlling a specific odor component, which is generated from impurities and/or by-product derived from the raw material, after the high temperature process. In this way, an embodiment of the present invention successfully provides a water absorbent agent not causing odor after the resin is swollen by absorption.

  • Patent number: 6569225
    Abstract: A breathable, stretch-thinned barrier film having improved strength, processability and/or breathability is formed from a mixture of a thermoplastic polymer and cavated filler particles such as cyclodextrin. The cavated filler particles provide the film with enhanced breathability to water vapor due to their ring-like, conical, cylindrical or otherwise hollow molecular structure, yet the film remains substantially impermeable to aqueous liquids. The enhanced breathability occasioned by the cavated particles permits the use of relatively low filler levels and correspondingly high polymer levels, thereby enhancing the film strength. The filler may melt during extrusion of the molten polymer into a film, facilitating smooth processing, and re-crystallize into particles after the film is formed and cooled.
