Composition for aqueous coating material, method for producing the same, and two-component curable aqueous coating material kit

摘要

Disclosed is a composition, which comprises water and a synthetic resin dispersed or dissolved therein, wherein the synthetic resin contains a fluorinated copolymer (A) comprising from 40 to 60 mol percentage of a structural unit of the formula (a1) e.g. chlorotrifluoroethylene, from 3 to 50 mol percent of a structural unit of the formula (a2) e.g. ethyl vinyl ether, from 4 to 30 mol percent of a structural unit of the formula (a3) e.g. hydroxyl butylvinyl ether and 1.4 to 6 mol percent of a structural unit of the formula (a4) e.g. hydroxyl butyl vinyl succinate (provided that the total mol percent value of the respective structural units of the formulae (a1), (a2), (a3) and (a4) is from 80 to 100); and which contains no organic solvent or an organic solvent in an amount of at most 3 mass percent in the total mass of the composition for aqueous coating material wherein Formula (a1) is ) CFX1-CX2X3 wherein X1 - X3 is defined in the specification and Formula (a2) - (a4) substituents are defined in the specification.
