  • the monsanto image of the dyed goods obtained is 3.5. Without the addition of preparation 2, the monsanto picture is only 1.
  • Example 5 The procedure described in Example 5 is followed, but using a liquor which instead of the optical brightener of the formula 108 has the same amount of an optical brightener of the formula or the formula contains, you also get level brilliant brightenings.
