Catalyst ink may be directly printed to a substrate using a stamp. Printed catalyst ink may converted to a pattern of one or more metal traces. Materials for a stamp and/or a substrate, and/or components of a catalyst ink, may be selected based on attraction of one or more of components of the catalyst ink to one or more print surfaces of the substrate and/or to one or more write surfaces of the stamp.

The present invention relates to a composition for forming a conductive pattern by irradiation of electromagnetic waves capable of allowing excellent formation of a conductive micro-pattern on various polymer resin products comprising a polycarbonate resin or on resin layers by a simple method such as irradiation of electromagnetic waves and plating, and capable of reducing the degradation of the physical properties of the resin products or resin layers caused by the irradiation of electromagnetic waves, a method for forming a conductive pattern using the same, and a resin structure having a conductive pattern. The composition for forming a conductive pattern by irradiation of electromagnetic waves comprises: a polymer resin comprising a polycarbonate resin; and an electromagnetic wave-absorbing inorganic additive which absorbs an electromagnetic wave having a wavelength in the infrared region and satisfies the characteristic that a laser sensitivity Ls defined by a predetermined relational expression is 1.6<−log(Ls)<6.0.

Tubulars are immersed in electroless nickel coating solution to coat the tubulars. Prior to the coating step the tubulars are blasted with a clean medium and washed and rinsed in alkaline solution. The tubulars are arranged in a bunk for washing, rinsing and coating. LLDPE stretch wrap applied to outer portions of the tubulars prevents coating of the outer portions. The tubulars are electrically separated from the bunk and the coating solution tank, and the tank is provided with anodic protection to prevent coating of the tank. The bunk is provided with a header assembly to provide solution flow through the tubulars via nozzles on the header assembly in addition to flow caused by the vortex effect created by velocity of fluid exiting the nozzles. The bunk is arranged in the solution tank so that the tubulars are at an angle to horizontal to efficiently remove hydrogen gas. Solution flow to the header assembly is filtered to remove particulates.

A method for applying a metal on a substrate comprises: a) applying a coating by treatment in a plasma, comprising a compound selected from alkanes up to 10 carbon atoms, and unsaturated monomers, and b1) producing polymers on the surface of the substrate, the polymers comprising carboxylic groups and adsorbed ions of a second metal, reducing the ions to the second metal, or alternatively b2) producing polymers on the surface, bringing the surface of the substrate in contact with a dispersion of colloidal metal particles of at least one second metal, and c) depositing the first metal on the second metal. Advantages include that materials sensitive to, for instance, low pH or solvents can be coated. Substrates including glass, SiO.sub.2 with very few or no abstractable hydrogen atoms as well as polymer materials containing halogen atoms can be coated with good adhesion.
