Photosensitive composition and pattern forming process using same.

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:
<CHEM>
wherein R1 and R2 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.
