  A photographic imaging system is disclosed comprised of a hardenable organic component containing ethylenic unsaturation sites and capable of imagewise modulating mobility as a function of addition at the sites of ethylenic unsaturation, coinitiators for ethylenic addition and, optionally, an imaging dye or a precursor thereof. The coinitiators include an azinium salt activator and a photosensitizer which is a dye exhibiting a reduction potential which in relation to that of said ionized azinium salt activator is at most 0.1 volt more posi­tive, with the further proviso that, when the photo­sensitizer is a keto dye having its principal absorp­tion peak at a wavelength shorter than 550 nm, it exhibits when excited by imaging radiation an inter­system crossing efficiency to a triplet state of less than 10 percent.

  本发明公开了一种照相成像系统，该系统由含有乙烯不饱和位点的可硬化有机成分、乙烯不饱和位点的加成函数、用于乙烯加成的辅助引发剂以及可选的成像染料或其前体组成。 辅助引发剂包括唑盐活化剂和光敏剂，光敏剂是一种染料，其还原电位与所述电离唑盐活化剂的还原电位相比至多正0.1伏，但进一步的条件是，当光敏剂是一种酮染料时，其主吸收峰的波长短于550纳米，在成像辐射的激发下，其到三重态的系统间交叉效率小于10%。
