  • Publication number: 20150361233
    Abstract: This invention provides a film having a novel function such that the film itself eliminates sebum dirt adsorbed on the film surface. The sebum absorption/diffusion film provided by the present invention is used for covering a surface of an article to prevent adsorption of sebum to the surface. It is characterized by absorbing sebum adsorbed on the film surface into the film and allowing it to diffuse inside the film.

  • Publication number: 20150320293
    Abstract: Provided is a sticky cleaner that can easily remove organic dirt adsorbed on a surface of an article with greater dirt-removing workability. The sticky cleaner provided by the present invention is used for removing organic dirt adsorbed on a flat surface of an article. The sticky cleaner comprises a dirt-collecting member that collects the organic dirt as it makes contact with the flat surface. In the dirt-collecting member, the part to make contact with the surface is formed with a PSA. The surface-contacting part of the dirt-collecting member exhibits an adhesive strength of less than 1 N/25 mm as a measured value based on the 180° peel test specified in JIS Z0237.
