Procedure

The condensate was dissolved in 400 ml of water and a solution of 41.8 g (0.120 mole) of sodium n-dode cylbenzenesulfonate in 600 ml of water was added to the resulting solution while stirring. The resulting yellow precipitate was obtained by filtering and dried, to give 44 g of n-dodecylbenzenesulfonate of the condensate of 4-diazodiphenylamine with glyoxylic acid.formaldehyde (diazo resin (a) of the present invention).
