摘要:
The invention comprises a toner receptive coating for substrates, typically paper, label or tag stock, for use in conventional printers such as ion deposition printers and photostatic copiers. The coating on paper or polymeric film improves the print density and durability of text or images transferred thereto from printers or copiers, particularly those which employ dry magnetic toner. The coating eliminates the need to use heat fusing to fix the transferred toned image to the substrate. The coating is composed of pressure sensitive polymeric binder material and particulate fillers. The polymeric binder has a glass transition temperature less than 20.degree. C. preferably a glass transition temperature between -10.degree. C. and +10.degree. C. The fillers include a polymeric filler, typically a polyethylene wax or a polyethylene/polytetrafluoroethylene wax mixture and a mineral filler, typically particulate silicon dioxide. The receptive coating also improves the smudge resistance of transferred toned images, particularly when employing dry magnetic toner. The coating can be used to fix (without heat fusing) the transferred toned image to paper, tag or label stock that has been coated with a pressure sensitive adhesive on the opposite side.
摘要:
Novel solvent processible electrically conductive coatings of conductive particle (e.g. silver) filled polysulfones. The coating compositions are useful in a variety of environments, especially in the manufacture of tantalum capacitors. The coatings advantageously are extremely heat stable to withstand high temperature soldering and attach to solder without thermal decomposition.
摘要:
A low cost, easy to use cleanser and/or treatment formulation (available in a powder, liquid, or solid form) includes encapsulated, non-toxic, timed-release dye. The dye remains encapsulated during cleansing and/or treating, such as during hand washing for the recommended 15-20 seconds. The encapsulant then releases the dye indicating that the hands have been thoroughly washed. Once the dye/lather mixture is completely removed by rinsing, the hand washer is assured that his or her hands have been thoroughly washed and rinsed completely. In those cases where an anti-bacterial agent is recommended, it should be used for the recommended 15-20 seconds, in order to be effective. The invention may be formulated for any type of timed cleaning and/or treatment, including hair washing, pet cleaning, hair coloring, and so forth. The cleansing formulation may be aqueous or organic based and may include encapsulated scents, lotions, medicants, therapeutic agents, and/or anti-microbials.
