Photosensitive composition

摘要

Disclosed is a photosensitive composition useful for preparation of various imaging materials and having good stability over time and a high sensitivity. The composition comprises a polymerizable monomer, a photopolymerization initiator, and a diazonium salt having a specific, borate anion portion represented by the general formula (I-1) or (I-2) given below, or the like. A combination of a specific borate compound and a general-purpose diazonium salt can also be used in place of the above-mentioned diazonium salt.
