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.
Claims19
A photosensitive composition capable of being applied to a substrate as a film, where light-exposed parts thereof are capable of turning tacky to fix powders thereon, which comprises an aromatic diazonium salt which gets sticky upon exposure to light and a salt of a compound represented by the general formula:
- ##STR11## (wherein R.sub.1 and R.sub.2 each represents a straight chain alkyl group, 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), wherein the amount of the salt of a compound represented by the general formula is within the range of 300-1% by weight based on the aromatic diazonium salt, whereby said salt of a compound represented by the general formula increases the photolyzing efficiency of said aromatic diazonium salt.
