Related product properties are improved, such as optical properties like the glossiness and transparency (see Table 11.1). There are no negative consequences for dye manufacturing tvith the new microreactor-made crystals, as the tinctorial power is the same as for conventional synthesis. Tinctorial power is a measure for the adhesion of the pigment to wool stuff or similar material. The intensification in coloration properties means that the same amount of material can be treated now with less amount of the Yellow 12 azo pigment, which reduces materials costs and increases the profitability of the pigment manufacture.
