Title:
AQUEOUS DEVELOPER FOR FLEXOGRAPHIC PRINTING PLATE, AND METHOD FOR PRODUCING FLEXOGRAPHIC PRINTING PLATE
Document Type and Number:
WIPO Patent Application WO/2022/045280
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: an aqueous developer for a flexographic printing plate, the aqueous developer being capable of maintaining good developing properties, and suppressing the aggregation of a dispersed substance in a developer diluted with water after repeated use; and a method for producing a flexographic printing plate using the aqueous developer. An aqueous developer for a flexographic printing plate according to the present invention contains a nonionic surfactant represented by formula (1) and water. (1): R1O-(AO)n-H Here, in formula (1), R1 represents a linear aliphatic hydrocarbon group having 9-30 carbon atoms. A represents an alkylene group having 2-4 carbon atoms. n represents an integer of at least 7, and when n is an integer of at least 2, a plurality of A's may be the same as or different from each other.
