摘要： An optical contact of a patternwise powdery coating layer is improved by permeating a substantially transparent inorganic material having a refractive index of 1.2 to 2.0 into a patternwise powdery coating layer formed on a substrate, thereby forming a mixture layer of the transparent inorganic material and the powdery coating layer between the patternwise powdery coating layer and the substrate.

摘要： The sensitivity of a photosensitive composition based on an aromatic diazonium salt which gets sticky upon exposure to light, is improved by adding a salt of a compound of the general formula:
wherein R 1 and R 2 each represents a straight chain alkyl group, and X, Y and Z each represents H, a straight chain alkyl group or an alkoxy group, but two or more of X, Y and Z cannot be H at the same time. Such compositions are used to form a pattern of powder coat layer on a substrate, e.g. a colour television picture tube.

摘要： photosensitive composition for use in forming color picture tubes contains an aromatic diazonium compound of the general formula:
where R 1 and R 2 are straight chain alkyl radicals, R 3 and R 4 are each one of H, CH 3 or OCH 3 except that R 3 and R 4 cannot both be H, and A is CL½ZnCl 2 , BF 4 or HSO 4 . The sensitivity of the composition is approximately 10 - 20% higher than that of conventional compositions.
