Provided is a photosensitive conductive paste that is unlikely to gel, has superior storage stability and adhesion to a substrate, and can be formed into a fine and thick pattern. In a photosensitive conductive paste containing a powdered base metal, an organic binder having acidic groups and a photosensitive organic component, a powdered base metal processed by surface oxidation treatment and a material such as a polyvalent alcohol having at least four hydroxyls, which forms microgels by reaction with metal hydroxides present on the surface of the powdered base metal, is used.

The present invention is directed to a coating composition and its employment in a metallization process that facilitates bonding of brazing filler metals to treated refractory surfaces, such as ceramics. The coating can be applied in preselected areas of the refractory surface to define the target area for brazing. It is believed that when compositions of the present invention are employed with brazing or soldering filler metals, strong bonds between two non-metallic refractory bodies, or between a non-metallic refractory body to ferrous and non-ferrous metal can be attained. In one embodiment, the present invention is a coating composition applied to a refractory material prior to brazing, the composition being comprised of a group IVB transition metal component selected from the group consisting of a group UVB transition metal, a hydride thereof, mixtures of group IVB metals and/or hydrides thereof, a binder material, and a fluid carrier. For example, the group IVB transition metal component may be a group IVB transition metal selected from among titanium, zirconium, hafnium, and thorium, hydrides of these group IVB transition metals, and mixtures of these group members. In one embodiment, the group IVB transition metal component is titanium, titanium hydride, or mixtures thereof.

The use of guanidine salts of organic fatty acids (guanidine soaps) as vehicles and binders for coating substrate surfaces is disclosed. Being completely organic, the guanidine soaps can be burned off leaving no undesirable residue. Of special interest is the use of guanidine 2-ethyl hexanoate as the vehicle and binder for coating problematic surfaces such as in coating alumina fibers with platinum or zirconia. For this application the guanidine soap is used as a melt. For other applications the guanidine soap may be use in a solution with a variety of solvents, the solution containing chlorometalates or powdered metals, refractories or ceramics.

Provided is a photosensitive copper paste permitting the formation of a fine and thick copper pattern having high adhesion to a substrate, and having excellent preservation stability without causing gelation, and a method of forming a copper pattern, a circuit board and a ceramic multilayer substrate using the photosensitive copper paste. The photosensitive copper paste includes a mixture of an organic binder having an acid functional group, a copper powder and a photosensitive organic component. The copper powder has a surface layer having a thickness of at least 0.1 &mgr;m from the surface composed CuO as a main component. The copper powder also has an oxygen content of about 0.8% to 5% by weight.
摘要:
A method for forming a thick film pattern is provided which can easily perform pattern formation even when a photosensitive paste containing a powdered conductor at a high content and having a low optical transmittance is used and which can form a thick film pattern having a rectangular cross-section and superior high-frequency transmission characteristics. In addition, a photosensitive paste used therefor is also provided. The thick film pattern having a predetermined shape can be formed by the steps of determining the photocurable depth d of a photosensitive paste; coating with the photosensitive paste in consideration of the photocurable depth d so as to form a photosensitive paste film having a predetermined thickness t; exposing the photosensitive paste film; and developing the exposed photosensitive paste film. Preferably, the coating with the photosensitive paste is performed so that the relationship between the photocurable depth d of the photosensitive paste and the thickness t of the photosensitive paste film satisfies the equation tnulld.
