PURPOSE:To readily form a highly sensitive pattern on, e.g. a cathode ray tube graphic inner surface, by forming photo-stickiness film, with a photosensitive composition prepared by incorporating specific sensitizer in aromatic diazonium salt, exposing to light followed by adsorbing fluorescent powder on the resulting sticky area. CONSTITUTION:A photosensitive composition comprising (A) p-diazo-N,N-dimethylaniline chloride-zinc chloride double salt and (B) as sensitizer, pref. 2- 10wt% [based on the component (A)] of p-diazo-bromophenol chloride-zinc chloride double salt of formula (n is 1/2-1; A is H or Br) is coated on the inner surface of a color cathode ray tube graphic region to form thin film followed by light exposure of desired pattern to develop stickiness surface on the film and adsorbing thereon fluorescent powder, thus forming the objective pattern.
