    摘要： The invention is directed to a method for forming a metal coating on a substrate by applying an oxalate of a Group VIII element from the Periodic Table of the Elements to the substrate. The oxalate is selected so that it will decompose to a complex of a zero valent Group VIII element or a Group VIII element on exposure to an energy source. Microelectronic circuits, etch masks or metal contacts on superconductors can be formed by the method when the oxalate coating is exposed to an energy source through a mask or the energy source beamed at the oxalate to trace a pattern on it.The metal thus obtained can be subsequently coated by electroless compositions especially where the Group VIII element is a catalyst for electroless coatings such as palladium. Additionally, the metal coating may be coated by an electrolytic composition.Through hole plating can also be achieved by applying the oxalates of a Group VIII element in the through hole of a circuit board followed by exposure to an energy source optionally followed by the application of an electroless and/or electrolytic metal composition.

    摘要翻译： 本发明涉及一种通过将元素周期表中第VIII族元素的草酸盐施用到基材上而在基材上形成金属涂层的方法。 选择草酸盐，使其在暴露于能量源时将分解成零价VIII族元素或VIII族元素的络合物。 当通过掩模将草酸盐涂层暴露于能量源或者在草酸盐上辐射的能量源来追踪其上的图案时，可以通过该方法形成微电子电路，超导体上的金属接触或金属接触。 由此获得的金属可以随后通过无电组合物涂覆，特别是其中VIII族元素是无电镀涂层如钯的催化剂。 此外，金属涂层可以由电解组合物涂覆。 也可以通过将VIII族元素的草酸盐施加到电路板的通孔中，然后暴露于能量源，随后施加无电解和/或电解金属组合物来实现通孔电镀。

    摘要： An electrochemical color change cell incorporating as a color changing agent intramolecular charge transfer salt or an intermolecular charge transfer salt. The intermolecular charge transfer salts and the intramolecular charge transfer salts have a plurality of oxidation states and a wide variation in color change. The intermolecular and intramolecular charge transfer salts preferably contain a violene moiety and a moiety having a carbonyl group conjugated to an aromatic moiety. The intramolecular charge transfer salts have a stable covalent radical-anion/radical-cation configuration. The intermolecular charge transfer salts have a stable ionic radical-anion/radical-cation configuration.

    摘要： Certain organic polymeric materials are capable of reversibly accepting or donating electrons from a reducing entity. The redox sites in the polymer accept electrons and, as a result, a change in the properties of the polymer occurs. This change is useful in modifying or etching the polymeric material. The material can be modified by incorporation of metallic seeds into the material at a controlled depth. The seeds are incorporated by interaction of cations of the metals with the redox sites in the polymer, which cause the reduction of the cations to form the neutral metallic seeds. Subsequent exposure of the polymeric material containing the seeds to an electroless bath causes further deposition of metal having the desirable characteristic of good adhesion to the polymeric material. Etching of the polymeric material can be carried out as a result of an increase in solubility of the polymer in aprotic solvents when its redox sites have accepted electrons. The increased solubility allows openings to be etched in certain areas of the polymeric material that have been reduced, leaving other areas unchanged.
