1264 SuperFAST Yellow TR C.I.NO.:PY74 Pigment Yellow 74 transparency type

P.Y.74, a commercial pigment of considerable significance, is used primarily in the printing ink and paint industries. Its greenish yellow shades are somewhere between those of P.Y.3 and P.Y.1. The pigment is considerably stronger than and superior to all comparable monoazo yellow pigments. P.Y.74 grades with very different particle sizes are commercially available.Varieties with fine particle sizes, i.e., pigments with specific surface areas between approximately 30 and 70 m2/g, are used primarily in the printing ink industry. They provide brilliant prints, which are brighter and more transparent than those of other monoazo yellow pigments. P.Y.74 is somewhat more greenish than the standard yellow. Its shade can be adjusted with suitable reddish yellow pigments.

P.Y.74 specimens are fast to alkali, acid, and soap. Other aspects of their fastness in print, such as butter resistance and fastness to the solvent mixture described in DIN 16 524

P.Y.74 varieties with comparatively fine 2.3.4 Commercially Available Monoazo Yellow and Orange Pigments 225 particle sizes are also used in the paint industry, where they lend color to air drying and emulsion paints. Excellent tinctorial strength, especially in pastel shades, i.e., in white reductions, make P.Y.74 more advantageous on a cost/performance basis than the somewhat redder P.Y.1. A strong tendency to bloom, however, precludes the use of P.Y.74 in baking enamels.
