All commercial benzimidazolone azo pigments are produced by classical azo cou­pling, commonly carried out in aqueous media. As mentioned already above, in yel­low and orange pigments the coupling component is 5-acetoacetylaminobenzimida — zolone (1) (apart from one exception, P. O. 64). In red pigments the naphthol deriva­tive 5-(2′-hydroxy-3′-naphthoylamino)-benzimidazolone (2) serves as coupling com­pound. Both coupling […]

Since 1950, particular efforts have been made to develop new azo pigments that combine excellent overspray fastness and bleed resistance with high fastness to light as well as weathering. As a result of this work, two different concepts found by Ciba and Hoechst, respectively, proved to be very successful: 1. Enlarging the pigment molecule, as […]

Hans-Joachim Metz and Frank Morgenroth 10.1 Introduction Benzimidazolone pigments are azo colorants that derive their name from the benzimidazolone group which is introduced as part of the coupling component. Apart from one exception1 there are two coupling components of commercial importance: 5-acetoacetylaminobenzimidazolone (1) and 5-(2′-hydroxy-3′- naphthoylamino)-benzimidazolone [Naphtolon™] (2) (see Figure 10.1). Figure 10.1 The two […]

For the specialty chemical business and especially for the organic pigments seg­ment, organic HPPs remain an attractive business. The fact that five major suppli­ers continue to dominate the market is another reason why most pigment produc­ers would like to get at least a minimum share. However, entry barriers are much higher than for example with […]

I believe that for quality reasons the big paint producers in Europe and USA are more likely to consume HPPs than the small and middle size paint producers in developing countries. However, because of the merger and acquisition policy of the major paint pro­ducers, these companies are extending their presence into Asia, India and South […]

As in the case of textile dyes, lower cost azo pigments are acquiring more and more the character of “commodities”. For this reason it is logical that the major pigment producers focus their research and development activity on HPPs. The goal of finding new or modified HPPs is the reason why BASF, CIBA and Clar […]

Several new market segments are becoming more and more attractive for HPP suppliers. Well-known examples are non-impact printing (Ink Jet), high tech security printing, and pigments for optical storage (compact disc, digital versatile disc, etc.). Other new technologies will certainly emerge requiring the use ofmore High Performance Pigments. Several other driving factors can shift the […]

• There is a continuing switch from inorganic pigments to HPPs for quality and environmental reasons (for example, the ban in some applications of lead chromate pigments). In these applica­tions there is also a growing demand for brilliant colors, and this leads to further replacement of the duller inorganics by organic pigments. 9.5.1.1 Plastics • […]

For the total organic pigment market the growth rate is estimated at 2-3%. For HPPs there seems to be a common belief that the future demand will grow around 5% per annum. What are the factors which are driving this demand? 9.5.1 Market Requirements and Trends In this group I include governmental and environmental regulations […]

How is the worldwide “trade flow” for High Performance Pigments? In order to establish a trade balance we need, in addition to the consumption figures, a “guestimate” of the production volume by regions (Table 9.1). 9.4 The Demand for HPP by Consumer Market Segments 135 Table 9.1 Production site of main HPP producers. Producers Main […]
