ABSTRACT:
A photosensitive composition improved in sensitivity by adding a salt of a compound represented by the general formula: ##STR1## (wherein R.sub.1 and R.sub.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 can not be H at the same time) to an aromatic diazonium salt which gets sticky upon exposure to light.
