    • Mixtures of a metal salt of formula ##STR1## and a metal salt of formula ##STR2## in which formulae (1) and (2) Me is a metal ion of valency n,n is 2, 3 or 4, andeach of the rings A and B independently of the other is unsubstituted or substituted by halogen, lower alkyl, lower alkoxy or an .alpha.-methylbenzyl radical, are prepared by reacting 2 moles of salicylic acid with at least 2 moles of a 1-phenylethanol of formula ##STR3## and at least 2 moles of a 1-phenylethanol of formula ##STR4## in which formulae (3) and (4) the benzene rings A' and B' are unsubstituted or substituted by halogen, lower alkyl or lower alkoxy, in the presence of a halide of a polyvalent metal having an atomic weight from 26 to 66 and, in a further step, reacting 2n moles of the resultant mixture of the salicylic acid compound of formula ##STR5## and the salicylic acid compound of formula ##STR6## in which formulae (5) and (6) A and B are as defined for formulae (1) and (2), with 2 moles of the salt of an n-valent metal of an inorganic acid or of a lower aliphatic carboxylic acid, where n has the given meaning.The mixtures of metal salts are particularly suitable for use as color formers in pressure- and heat-sensitive recording materials.
    • 式(1)的金属盐和式(1)和(2)的金属盐的混合物,其中式(1)和(2)Me是化合价n,n的金属离子是2,3或 4,并且环A和B各自独立地是未被取代的或被卤素,低级烷基,低级烷氧基或α-甲基苄基取代的物质,是通过使2摩尔水杨酸与至少2摩尔的1 (3)的苯基乙醇和至少2摩尔的式(3)和(4)苯环A'和B'的未取代或取代的式(4)的1-苯基乙醇 在卤素,低级烷基或低级烷氧基的存在下,在原子量为26至66的多价金属的卤化物的存在下,并且在另一步骤中,将2摩尔所得的式IMAGF的水杨酸化合物 (5)和其中式(5)和(6)A和B如式(1)和(2)所定义的式(IMA)(6)的水杨酸化合物与2摩尔 无机酸或低级脂肪族羧酸的n价金属的盐,其中n具有给定的含义。 金属盐的混合物特别适合用作压敏和热敏记录材料中的成色剂。
