Document Type and Number:
WIPO Patent Application WO/2024/048625
Kind Code:
A1
Abstract:
Provided is a method for treating an aqueous developer waste liquid that is generated due to development of a flexographic printing original plate using an aqueous developer liquid, the method including: a first filtration step in which an aqueous developer waste liquid at 5-48°C inclusive is filtered using a microfiltration membrane to obtain a recovered liquid and a concentrated waste liquid; and a re-use step in which the recovered liquid is re-used in development of a flexographic printing original plate.
