摘要:
Writing instruments are provided comprising a) a friction transferable binder comprising a colorant, and b) frangible microcapsules containing a liquid solvent. The writing instrument contains sufficient microcapsules to provide a Coloration Uniformity Percentage (defined herein) of at least about 25%.
摘要:
A device provides liquid material for application to a surface. The device comprises in order at least a carrying substrate, frangible microcapsules containing the liguid to be applied, a raised area around the microcapsules of a structurally rigid material, and a flexible, liquid permeable material overlaying the microcapsules. Pressure on the liquid permeable material ruptures the microcapsules and enables the liquid to flow through the permeable material.

In the manufacture of magnetic recording media, coatings are applied from water-borne dispersions of inorganic particles, a polymer containing functional groups and an agent for crosslinking the polymer, the crosslinking agent being a polyfunctional aziridine such as ##STR1##
摘要:
A fragrance-delivery composition is provided having cake-forming components and microcapsules containing fragrance oil. The composition is a coherent cake, and has a VOC content less than 250 grams of per liter less water, fragrance oil and exempt solvents.
摘要:
Disclosed is a device for selectively indicating strain comprising a layer of polymeric binder and, distributed in or adjacent to the binder layer, microcapsules containing an indicating means, whereby when the binder is stiff, minor flexure of the device causes rupture of the microcapsules and releases the indicating means. This device has a non-stiff state such that a given strain applied to the binder layer in the non-stiff state will not release the indicating means, and a stiff state such that the same given strain applied to the binder layer in the stiff state will release the indicating means. Also disclosed is a method for determining exposure of an article to a given low temperature.
摘要:
The disclosure relates to abrasive articles useful in chemical-mechanical polishing (CMP), the articles including a substrate with opposite major surfaces, an abrasive material overlaying at least a portion of at least one of the major surfaces, and at least one of a radio frequency identification (RFID) tag, a RFID tag reader, or a sensor for providing CMP information to a transmitter positioned near the substrate, the transmitter positioned near the substrate and adapted to wirelessly receive CMP information and wirelessly transmit the CMP information to a remote receiver. The disclosure also relates to a CMP pad conditioner for wirelessly communicating CMP information to a remote receiver, a CMP process monitoring system for wirelessly communicating CMP information to a remote receiver, and a method for conditioning a CMP pad using a CMP process monitoring system for wireless communicating CMP information to a remote receiver.
摘要:
Internally replenished gas-containing enclosures are described. Such enclosures include a replenishing gas source internal to the enclosure, wherein the gas source comprises a gas contained within a permeable membrane. Exemplary gas sources include a plurality of bubbles and pouches. Materials useful for the permeable membrane include glass, glass ceramics, metals, metal oxides, polymeric films, as well as combinations of such materials. The gas source may be located within the enclosure or it may be incorporated into a resin (e.g., an adhesive or a gasket) positioned between sections of an enclosure. Methods of internally replenishing an enclosure are also described.
摘要:
Water-based pigmented ink formulations are disclosed including a water soluble or water dispersible silicone-containing polymer additive comprising a vinyl silicone polymer. The additive significantly reduces kogation, mudcracking, and banding in some or all of the pigmented ink formulations.
摘要:
An apparatus for delivering one or more aromas at selected times includes a housing with a receptacle and an aroma delivery device detachably received in the receptacle. The aroma delivery device includes a carrier having a plurality of aroma-bearing elements that are selectively communicated with an air passageway for providing one or more aromas as desired. The device is especially useful for providing a realistic sensory experience in an interactive or non-interactive use, and may be used in such diverse settings as the entertainment industry, the educational training field or a medical arena.
摘要:
A method of modifying a surface comprising the steps of: (a) contacting the surface to be modified with a working surface of an abrasive article, the abrasive article comprising a phase separated polymer having a first phase and a second phase, the first phase being harder than the second phase; and (b) relatively moving the surface to be modified and the fixed abrasive article to remove material from the surface to be modified in the absence of an abrasive slurry.
