  • Publication number: 20010031342
    Abstract: Image transfer media and methods of transferring images are provided. The image transfer media comprise a sheet having a nonporous micro-embossed surface topography comprising cavities on one major surface of the sheet and an ink release coating on the embossed surface, wherein said major surface has a surface energy of about 43 dyne/centimeter or less. A method of transferring an image to a substrate comprises the steps of (a) printing a selected image onto an imaging surface of an image transfer medium of the invention; (b) contacting the imaged micro-embossed surface with the substrate using pressure; and (c) removing the micro-embossed surface of the image transfer medium from the substrate.

  • Patent number: 5908663
    Abstract: A method for treating carpets is provided which obviates the need for scouring. In accordance with the method, an unscoured carpet is treated topically, and by means of a low wet pickup method, with a solution comprising particles of silica or a similar inorganic additive and a fluorochemical or other optional organic additive. Carpets treated in accordance with this method are found to have excellent soil resistance properties which do not decrease noticeably with subsequent wear or cleaning. Furthermore, since the method involves a low wet pickup, the required drying times are significantly reduced as compared to conventional aqueous bath immersion methods.

  • Patent number: 5888290
    Abstract: A fluorochemical treatment composition comprises (a) a sol comprising a colloidal dispersion of substantially discrete, substantially monodisperse in size, polymer-grafted, inorganic microparticles in liquid; and (b) at least one fluorochemical. The composition can be used to impart durable water and oil repellency, stain release, and dry soil resistance to a variety of substrates.

  • Patent number: 5760126
    Abstract: Water-based coating compositions comprise an aqueous solution, emulsion, or dispersion of (a) a water-soluble or water-dispersible polymer or oligomer having at least one anionic moiety which is capable of reacting with an oxazoline or oxazine moiety; (b) a water-soluble or water-dispersible polymer or oligomer having at least one oxazoline or oxazine moiety; and (c) a sol comprising a colloidal dispersion of surface-modified, inorganic microparticles in liquid; at least one of the components (a), (b), and (c) further comprising at least one fluoroaliphatic moiety. The compositions can be used to form hard coatings having low surface energy and high abrasion resistance.
