ABSTRACT:
A patternwise coated powder layer can be formed by a process comprising the steps of coating a photosensitive composition, which contains an aromatic diazonium salt as a photosensitive component and becomes sticky by exposure, onto the surface of a substrate to form a thin layer, subjecting the thin layer to patternwise exposure with actinic radiation to produce stickiness at the exposed area, and then contacting powder particles with the thin layer after exposure to make the thin layer to accept the powder particles according to the powder acceptability of the thin layer. According to this process, for example, the phosphor screen of a color picture tube can simply be produced.
