Abstract

1304625 Coating with metals SIEMEN A G 26 Feb 1970 [27 Feb 1969] 9302/70 Heading C7F [Also in Division H1] An electrical conductor pattern is formed on an insulating surface by exposing to light, through a negative of the required pattern, an insulating surface having incorporated therein a light-sensitive material which, on exposure to light is converted to a reducing agent, and then electrolessly depositing the metal pattern.
