摘要： A metal composition such as metallic fluid or metallic paste is prepared by compounding a metal acetilide represented by the general formula M(-CC-R)n (wherein M is a metallic atom, n is the valency of the atom M, and R is a hydrocarbon group optionally bearing oxygen) as an organometallic source with a resin and an organic solvent and kneading the mixture. When the composition is applied in a desired pattern to a required portion of a decorative article, such as porcelain or glass, or an electronic part and at least the required portion is dried and heated, the organic substances except for the metal are decomposed and released and only the metal is sintered in the required pattern.

摘要： A novel compound which is used as an organic metal complex for metal pastes and the like, is free from sulfur and chlorine, and hence can contribute to the purification of the environment; and a process for preparing the same. Specifically a metal acetylide compound represented by the general formula M(-CC-R)n, wherein M represents a metal atom; n represents the valency of the metal atom M; and R represents a hydrocarbon group having one to eight carbon atoms and optionally containing an oxygen atom. As this compound contains neither sulfur non chlorine, it emits neither sulfur dioxide gas nor chlorine compounds, when used for metal pastes and the like, thus contributing to the purification of the environment. Use of a solid sulfite as a metal reducing agent facilitates stoichiometrical control of the reaction and preparation of a metal acetylide compound. Further, since this process does not evolve sulfur dioxide gas, it is free from the fear of environmental pollution and can contribute to the purification of the environment.

摘要翻译： 本发明涉及不含硫或氯的新型化合物及其制造方法，因此有助于作为有机金属配合物在金属糊等中的清洁作用。 由通式M（-CIDENTICAL CR）n表示的金属乙炔化合物（式中，M表示金属原子，n表示金属原子M的价数，R表示碳原子数为1〜8的烃基） 其可以含有或不含有氧原子）作为新的有机金属配合物。 由于这些化合物不含硫或氯，所以即使将糊料固定在金属糊等中，也不会释放出亚硫酸气体或氯化合物。 因此，这些化合物有助于清洁环境。 在本发明中，固体亚硫酸盐用作金属还原剂; 因此，反应的简单化学计量控制是可能的，使得容易获得金属乙炔化合物。 此外，由于在该制造方法中不产生亚硫酸气体，所以不关心环境污染，因此有助于清洁环境。
