| titleOfInvention | Process for producing alkali-soluble copolyester |
| abstract | PROBLEM TO BE SOLVED: To provide a method for efficiently producing a copolymerized polyester having a metal sulfonate group-containing isophthalic acid component at a high concentration. SOLUTION: In a method for producing a polyester copolymerized with a mole% of isophthalic acid containing a metal sulfonate group and / or an ester-forming derivative component thereof in a range satisfying the following formula 1 with respect to a total acid component. Before the esterification reaction or transesterification reaction, b weight% with respect to 100 parts by weight of the copolyester capable of obtaining the lithium atom addition amount in the lithium compound in the range satisfying the formula 2 and a manganese compound in the range satisfying the formula 3 The present invention can be provided by the method for producing an alkali-soluble polyester obtained by adding c wt% to 100 wt parts of the copolyester capable of obtaining the manganese atom addition amount of 15.0 ≦ a ≦ 40.0 (formula 1) {(b × 1000) −17} /a≧2.0 (formula 2) {(c × 1000) +11.2} /a≧2.2 (formula 3) 【Selection diagram】 None |
