The condensate was suspended in a mixture of 200 ml of water and 500 ml of MEK and a solution of 41.8 g (0.120 mole) of sodium n-dodecylbenzenesulfonate in 600 ml of water was added to the resulting suspension while stirring. When the suspension was stirred for a while and then allowed to stand, it separated into two phases. The upper phase was poured into 2 l of water while stirring and the resulting yellow precipitate was collected by filtering and dried, to give 46 g of n-dodecylbenzenesulfonate of the condensate of 4-diazodiphenylamine with terephthalaldehydic acid (diazo resin (c) of the present invention).
