All chapters in the fourth edition have been thoroughly reviewed, revised, and

updated. More than 130 formulae were added or revised. About 170 figures

were added. The chapter on legislation, ecology, toxicology was completely

rewritten and now represents the latest developments.

Actually “Azo pigments” do not exist. All single-crystal structure analyses as

well as spectroscopic investigations reveal that no commercial “Azo pigment”

contains an azo group, but they exhibit the hydrazone-tautomeric form instead1).

Consequently all commercial “azo pigments” should be called “hydrazone pigments”.

This nomenclature has been employed throughout this book. We hope,

that the correct denomination “hydrazone pigment” finds its way to all publications

on organic pigments as well as to the labelling of products etc.

The properties of organic pigments depend on their crystal structures. Correspondingly

all available information on the crystal structures of all industrial

organic pigments has now been included and almost every crystal structure is

depicted by a figure. The effect of the crystal structure and the polymorphism of

a pigment on its colouristic and physical properties is described in detail. The

new co-author of this book, Prof. Dr. Martin U. Schmidt, has been researching

organic pigments since 1995, with a focus on their polymorphism and their crystal

structures.

Several sections have been moved to other chapters in the 4th edition. Most

triarylcarbonium pigments and most metal complex pigments are neither hydrazone

nor polycyclic pigments, hence their description now appears in chapter 4

(Miscellaneous Pigments). The section on isoindoline and isoindolinone pigments

has been moved to chapter 3 (Polycyclic Pigments).

We pay tribute to our deceased colleagues Dr. Willy Herbst, who was the

former coauthor of the book, and Prof. Dr. Erich F. Paulus (Goethe University,

Frankfurt, formerly at Hoechst AG), who worked on polymorphism and singlecrystal

structure analyses of organic pigments for 43 yea
