Abstract: A process for preparing a disazo dye represented by the following formula: ##STR1## wherein R.sup.1 and R.sup.2 each represents a hydrogen atom, a halogen atom, a nitro group, a trifluoromethyl group, a lower alkoxycarbonyl group or a lower alkylsulfonyl group, R.sup.3 represents a lower alkyl or allyl group which may optionally have a substituent or substituents, and R.sup.4 represents a lower alkyl or allyl group having a substituent or substituents, which comprises diazotizing an amine represented by the following formula: ##STR2## wherein R.sup.1 and R.sup.2 are the same as defined above, and coupling the diazotized product with a bis(N,N-di-substituted anilino)methane represented by the following formula: ##STR3## wherein R.sup.3 and R.sup.4 are the same as defined above.
