ABSTRACT:
Orthorhombic greenish-tinged lead chromate pigments containing lead chromate and lead sulfate in a weight ratio of 91:9 to 100:0 and distinguished by a tinctorial strength of 0.053 to 0.066 at a standard depth of color of 1/25 in accordance with DIN 53235 are obtainable by mixing an aqueous solution of a lead salt with an aqueous solution of a chromate and, if necessary, of a sulfate under high turbulence in the presence of an aluminium salt and in the absence of zinc salts.
