反応手順
Example 2 was repeated in every detail except that part of the 2-hydroxy-3-naphthoic acid in the solution thereof was reacted with sodium hypochlorite before addition of the Rosin N solution. Example 3 contained 1% (0.0007 mole), Example 4 contained 2% (0.0014 mole) and Example 5 contained 4% (0.0028 mole) of 10% sodium hypochlorite solution to form, in each case, 1-chloro-2-hydroxy-3-naphthoic acid in situ. The ratio of amino sulfonic acid/coupling component in Examples 2-5 is 1/1.07 (0.0727/0.068 moles).
