Abstract: An organic vehicle comprising at least about 0.5 wt % and no more than about 45 wt % of at least one of a natural essential oil, based upon 100% total weight of the organic vehicle, at least about 0.5 wt % and no more than about 10 wt % of at least one resin, an organic solvent, and a thixotropic agent is provided. The invention also provides a solar cell and a method of forming a solar cell with the electroconductive paste of the invention.

Abstract: The present invention provides methods of forming and detecting non-visible marks and articles marked in accordance with the methods. In accordance with the methods of the invention, a marking material is applied to a substrate to form a mark that is contrastable from the substrate in one or more regions of the infrared portion of the electromagnetic spectrum. The mark is covered with a film, which can be a bonded coating or a non-bonded covering sheet, that comprises an amount of one or more inorganic pigments such that the film appears opaque in the visible portion of the electromagnetic spectrum but is sufficiently transmissive in one or more regions of the infrared portion of the electromagnetic spectrum to facilitate the detection of the mark covered by the film. The non-visible marks can be applied to articles such as automobile parts, aircraft parts and other articles of manufacture to deter counterfeiting.

Abstract: A method of decorating laminated glass is disclosed. A pigment package composition comprising a cross-linkable thermoset resin, a crosslinker capable of crosslinking the thermoset resin, and a pigment is applied to a glass substrate. The crosslinker and thermoset resin are cured at a relatively low temperature (ca. 400° F.). The use of an organic based pigment composition allows use of thinner glass sheets than with traditional ceramic enamel pigment compositions.
