  • Patent number: 7682771
    Abstract: In one aspect, the invention provides a fluorochemical composition comprising a mixture of: a fluorochemical selected from the formula: wherein RF is a fluorinated group having the formula: Rf—W—, wherein Rf is a perfluoroalkyl or perfluoropolyether group and W is a divalent linking group; PI is a monovalent pendant organic moiety comprising benzophenone, substituted benzophenone, acetophenone, or substituted acetophenone groups; R is H, CH3, or F; Rh is lower alkyl selected from the group consisting of linear or branched alkyl groups having from 1 to about 8 carbon atoms, cycloalkyl-containing alkyl groups having from 4 to about 8 carbon atoms, and cycloalkyl groups having from 3 to about 8 carbon atoms, all optionally containing catenated O or N atoms; m is at least 2; n is at least 1; q is zero or greater; and a hydrofluoroether.

  • Publication number: 20090000727
    Abstract: A hardcoat film article comprises a cured hardcoat layer disposed on a release liner. The release liner comprises a release material formed by irradiating a release material precursor, wherein the release material precursor has a shear storage modulus of about 1×102 to about 3×106 Pa when measured at 20° C. and at a frequency of 1 Hz, and wherein the release material has a contact angle of 15° or more, as measured using a mixed solution of methanol and water (volume ratio 90:10) having a wet tension of 25.4 mN/m.

  • Publication number: 20080039805
    Abstract: A patch application device wherein the patch is retained in position within the collar until delivery through contact of at least one obstruction inside the collar with a portion of an adhesive on the front surface (e.g., microneedle-containing surface) of the patch. The collar and patch can be used to form separate replaceable cartridges, and the combination can be provided as a kit.
