PROBLEM TO BE SOLVED: To obtain a photosensitive composition having high sensitivity as a photosensitive material and excellent preservable property, enabling photosensitive wave length range to be widely selected and made utilizable as a light source including various lasers by consisting of a polymer having a heterocyclic group having a side chain bonded with mercapto group and an photo-acid generating agent. SOLUTION: This photosensitive composition consists of the polymer having a heterocyclic group having a side chain bonded with mercapto group and the photo-acid generating agent. As the polymer having the heterocyclic group having the side chain bonded with mercapto group, a polymer containing a repeating unit expressed by a formula or the like is mentioned. In the formula, R1 represents hydrogen atom or methine group and X1 represents nitrogen-containing heterocyclic group. L1 represents an optional connecting group to connect X1 to the polymer main chain and (n) represents 1 or 2. As the photo-acid generating agent, a S-triazine derivative substituted by a trihaloalkyl is preferable. As a result, the high sensitivity and excellent preservable property are attained as the photosensitive material, the range of the photosensitive wave length is widely selected and utilization as the light source including various lasers is enabled. |
