Claims11
A polythiol composition, comprising:
- a polythiol compound (A);
- and a compound represented by the following formula (1):
- wherein, in formula (1), m and n each independently represent 0 or 1, and m+n=1,
- wherein the polythiol compound (A) comprises 4-mercaptomethyl-1,8-dimercapto-3,6-dithiaoctane, or comprises a mixture of 5,7-dimercaptomethyl-1,11-dimercapto-3,6,9-trithiaundecane, 4,7-dimercaptomethyl-1,11-dimercapto-3,6,9-trithiaundecane, and 4,8-dimercaptomethyl-1,11-dimercapto-3,6,9-trithiaundecane, and
- wherein, in a high-performance liquid chromatography measurement, a peak area of the compound represented by formula (1) is 10.0 or less with respect to a total peak area 100 of compounds included in the polythiol composition.
