PURPOSE:To obtain a photosetting type photosensitive compsn. which is free from the decomposition occurring in moisture and has an excellent shelf life by compounding prescribed amts. of an orthoquinonediazide compd. and a cationic high polymer electrolyte thereby preparing the photosensitive compsn. CONSTITUTION:An orthoquinonediazide compd. is compounded at 0.01-0.5pt.wt. based on 1pt.wt. a cationic high polymer electrolyte, whereby a photosensitive compsn. is prepd. Various aliphat. or arom. hydroxy or amino compds. and sulfonate and sulfonamide of orthoquinonediazide are suitable as the orthoquinonediazide compd. For the cationic high polymer electrolyte, a compd. of the structure having ammonium salt, sulfonium salt, etc. can be used for the basic skeleton. Said photosensitive compsn. is dissolved in water, methanol, etc. and the soln. is coated on backing. |
