Abstract
An aqueous developer for a flexographic printing plate capable of maintaining good developability and suppressing aggregation of a dispersion in the developer diluted with water after repeated use is provided, as is a manufacturing method of a flexographic printing plate using the same. The aqueous developer for a flexographic printing plate contains a nonionic surfactant represented by Formula (1), and water, where Formula (1) is R1O-(AO)n—H. In Formula (1), R1 represents a linear aliphatic hydrocarbon group having 9 to 30 carbon atoms, A represents an alkylene group having 2 to 4 carbon atoms, and n represents an integer of 7 or more, provided that a plurality of A's may be the same or different from each other.
Claims7
An aqueous developer for a flexographic printing plate, comprising:
- a nonionic surfactant represented by Formula (1);
- an anionic surfactant represented by Formula (2);
- and
- water,
- R1O-(AO)n—H (1)
- here, in Formula (1),
- R1 represents a linear aliphatic hydrocarbon group having 9 to 30 carbon atoms,
- and wherein R1 in Formula (1) has an ethylenically unsaturated double bond,
- A represents an alkylene group having 2 to 4 carbon atoms, and
- n represents an integer of 7 or more, in which in a case where n is an integer of 7 or more, a plurality of A's may be the same or different from each other, and
- a content of the nonionic surfactant is 0.5% to 5% by mass,
- R2—X (2)
- here, in Formula (2),
- R2 represents an aliphatic hydrocarbon group having 7 to 15 carbon atoms, and
- X represents a carboxylic acid group or a salt of the carboxylic acid group, a sulfonic acid group or a salt of the sulfonic acid group, a sulfate group or a salt of the sulfate group, or a phosphoric acid group or a salt of the phosphoric acid group.
