<p>PURPOSE: To obtain a photosensitive bis(halogen-substituted methyloxadiazole) compound, having a photosensitive wavelength region in a near ultraviolet to a visible regions and useful as a photosensitive layer, a color proof, a photoresist, etc. CONSTITUTION: A derivative of formula I R<1> is Cn H2n , etc., [(n) is an integer of 1-10]; R<2> and R<3> are each independently H, a 1-10C alkyl, a 1-10C alkoxy, etc.; R<4> and R<5> are each independently H, a 1-10C alkyl, a 6-12C phenyl, etc.; X, Y and Z are each independently H or a halogen (except the case where X, Y and Z are H)}, e.g. a compound of formula II (R<1> is C4 H8 , etc.). The compound of formula I is obtained by cyclizing, e.g. a bis type N-cinnamoyl-N'- haloacetylhydrazine of formula III. The compound of formula I has high sensitivity without causing coloring of decomposed substances in exposure to light or preservation in the light.</p> |
