Recycling method of developing processing waste liquid concentration method and developing processing waste liquid

摘要

Infrared absorbing dye on a support, a polymerization initiator, and a polymerizable compound, a lithographic printing plate precursor having an image recording layer and the protective layer containing, after exposure, the anionic surfactant having a naphthalene skeleton and / or a nonionic surfactant containing 10 wt% 1 wt% having a naphthalene skeleton, an organic solvent content of the boiling point of 0.89 C. to 300 C. is not more than 2 wt%, pH is 6.0 to 9. obtaining a waste liquid arising in developing with a developer of 5, and the waste liquid amount of the development waste solution before the amount / concentration of the development waste solution after the concentration is 1 / 2-1 / 10 by volume developing processing waste liquid concentration methods, including step, the evaporated concentrated so.
