Summary:PURPOSE:To obtain a photosensitive compsn. reacting with high sensitivity even in the presence of oxygen by incorporating an arom. iodonium salt, a halogenated phthalocyanine pigment and a sensitizer having a specified photosensitive wavelength region into a cationic-polymerizable photosensitive compsn. CONSTITUTION:A cationic-polymerizable compd., an arom. iodonium salt, a halogenated phthalocyanine pigment and a sensitizer having 350-450nm photosensitive wavelength region are incorporated into a cationic-polymerizable photosensitive compsn. The halogenated phthalocyanine pigment hardly hinders cationic polymn., the cyan and green hues of the pigment highly transmit light in the wavelength region of 350-450nm and higher sensitivity can be rendered to the compsn. by adding the sensitizer having high sensitivity in the region. The compsn. an be cored with a simple exposing device and can be colored without lowering the sensitivity.
