PURPOSE:To increase sensitivity with a photo-cross linking agent and polyvinyl alcohol. CONSTITUTION:A photosensitive polymer containing at least one kind of monomer unit selected from among maleic acid, azide group as a water-soluble, photo-nonsensitive monomer unit, vinylazide benzylideneacetophenone sulfonic acid, vinylazide benzylideneacetophenone carboxylic acid, vinylazide cinnamylidenacetophenone sulfonic acid, vinylazide cinnamylidenacetophenone carboxylic acid, and their salts is used as a photo-cross linking agent, and polyvinyl alcohol of a water-soluble polymer is used as a base polymer to manufacture a photosensitive composition. |
