The present invention relates to a process for the production of certain compounds, especially dye compounds defined in general by Formula I: The invention provides a one-step method in which a compound of Formula II or a reactive intermediate derived in situ therefrom is reacted in situ with a compound of Formula III (optionally in the presence of a compound of Formula IV) to produce compounds of Formula I in excellent yield, and in a manner which avoids undesirable by- product formation.
