Although the research actIvItIes of dyestuff chemists worldwide
have been influenced to a great extent, in recent years, by the
need to respond to a variety of environmental issues associated
with the manufacture and application of synthetic dyes and
pigments, a significant level of targeted research continues to be
devoted to new chemistry aimed at enhancing the technical
properties of dyes in commerce. This book is a presentation of
various aspects of basic research conducted during the past decade
but not reported in the recent review literature. The coverage
herein is unique in that it emphasizes systematic approaches
commonly utilized in the design and synthesis of dyes and pigments
and the required intermediates. While it is well known that certain
transition metals are important in the synthesis of technically
viable metallized dyes for polyamide and protein fibers, these
metals are demonstrated in Chapter 1 also to be effective agents in
the regiospecific placement of substituents into azo compounds. The
scope and limitations of this chemistry are presented. In other
synthetic work, a description of the different processes employed
to produce the major families of reactive dyes is presented. In
Chapter 4, special attention is given to reactive dyes containing
more than one reactive group, and to the more recent developments
in the field. The two chapters which follow provide a review of the
recent literature pertaining to novel chromophores and dyes for the
D2T2 process, respectively.

At the beginning of this series of volumes on Color Chemistry, the
editors pointed to a number of events that have served as stimuli
for techno logical advances in the field, thus preventing dyestuff
manufacturing from becoming what might otherwise be viewed by now
as a 'sunset industry'. The volumes which followed have provided
ample evidence for our belief that the field of colour chemistry is
very much alive, though arguably in need of further stimulus. For
instance, a viable approach to the design of new chromophores and
to the design of metal-free acid, direct, and reactive dyes having
fastness properties comparable to their metallized counterparts
represent the kind of breakthroughs that would help ensure the
continued success of this important field. While it must be
acknowledged that serendipity 'smiled' on our discipline at its
inception and has repeated the favor from time to time since then,
few would argue against the proposition that most of the
significant advances in the technology associated with any
scientific discipline result from research designed to enhance our
understanding of the fundamental causes for experimental
observations, many of which are pursued because they are
unexpected, intriguing and intellectually stimulating. Little
reflection is required for one who knows the history of the
dyestuff industry to realize that this is certainly true in the
colour chemistry arena, as it was basic research that led to
fiber-reactive dyes, dyes for high technology, and modern synthetic
organic pigments."
