ABSTRACT:
The method of depositing a metal on a surface especially suitable for the manufacture of printed circuit boards includes coating the surface with a sensitizing solution comprising an inaqueous solvent solution, a reducible salt of a non-noble metal, a salt of 2,7 anthraquinone disulfonic acid and a polyol type secondary reducing agent such as sorbitol. The coated surface is then dried and the dried surface may be stored for extended periods of time before further processing which consists of imaging the sensitized surface with ultraviolet light and electrolessly plating a metal over the imaged surface.
