<P>PROBLEM TO BE SOLVED: To provide a photosensitive composition which is useful for the recording layer of a negative lithography original plate for recording patterns with an infrared laser and with which an image with superior dot reproducibility can be formed. <P>SOLUTION: The photosensitive composition contains a compound which is cured by exposure to infrared radiation. When the photosensitive composition is exposed to the infrared laser after being formed into a film, the electrostatic capacity of an exposed part increases at a rate ≤0.7 times that of an unexposed part. The increase rate of electrostatic capacity is measured by using a model liquid of an alkali aqueous solution having a pH selected according to an acid radical that a polymer in the composition has. <P>COPYRIGHT: (C)2004,JPO |
