A process for forming a pattern on the interior side of a face plate of a color picture tube by using a photosensitive composition comprising p-diazo-N,N-dimethylaniline chloride-zinc chloride double salt and a p-diazo-bromophenol chloride-zinc chloride double salt and conducting imagewise exposure of coated film of the photosensitive composition to light and contacting with powder particles at least one time gives higher sensitivity compared with a conventional process.
