Abstract:
A method for producing a binder resin comprises polycondensing a polycondensable monomer by using a polycondensation catalyst that comprises: at least one of compounds of formula (I) or (II); and at least one of compounds represented of formula (III) or (IV), wherein weight ratio of total amount of the compounds of formula (I) or (II) to total amount of the compounds of formula (III) or (IV) is from 5:95 to 95:5: wherein R1 represents a C8-C20 straight-chain alkyl group; R2 represents a monovalent organic group; and number n of substituents R2 represents an integer of from 0 to 4; R3—SO3H (II) wherein R3 represents a C8-C20 straight-chain alkyl group; wherein R4 represents a C8-C20 branched alkyl group; R5 represents a monovalent organic group; and number m of substituents R5 represents an integer of from 0 to 4; and R6—SO3H (IV) wherein R6 represents a C8-C20 branched alkyl group.
