ABSTRACT:
A photosensitive composition containing a 2-halomethyl-5-substituted-1,3,4-oxadiazole compound represented by the following general formula (I): ##STR1## wherein A represents a substituted or unsubstituted aromatic residue; X represents a hydrogen atom, a cyano group, an alkyl group or an aryl group; Y represents a chlorine atom or a bromine atom; and n represents an integer of 1 to 3.
The free radical generating agent represented by the general formula (I) has a photosensitive wavelength range from near ultraviolet range to visible range, high photo-decomposition sensitivity and good compatibility with other components present in the photosensitive composition.
The photosensitive composition is suitable for use in light-sensitive printing plates or photo-resists.
