PURPOSE:To enhance the developability and condensability of the developing soln. and to lower toxicity by incorporating propylene glycol, surfactant and water into the developing soln. CONSTITUTION:This developing soln. is the developing soln. for the original plate for the damping-waterless photosensitive planographic printing plate having a photosensitive layer and a silicone rubber layer and is formed by incorporating the propylene glycol, the surfactant (A) and the water. Sodium dibutyl naphthalene sulfonate, etc., are usable for the component A and further, the compounding of a base, such as sodium methasilicate, etc., with the developing soln. is possible as well. |
