The present invention relates to monoazo compounds of formula (I) which are present in the form of mono-, di-, tri- or tetra-valent mixed salts of different cations, such as, for example, Ca2+, Na+, NH4+, NR4+, H+, Li+, K+, Mg2+,Ba2+, Sr2+, AI3+, Pb2+, Mn2+, Zn2+, Cr2+, Co2+, Fe2+, Fe3+, Zr4+ and Cu2+, R being C1-C6alkyl, in freely selected ratios, and to the calcium salt of the monoazo compound of formula (I) which has two crystal polymorph forms - a reddish yellow and a greenish yellow - having different properties, for example colour shade or high-temperature stability, to the preparation of such compounds and to their use in the mass-pigmenting of organic materials and in the production of wax transfer ribbons, toners or colour filters.
本发明涉及公式(I)的单偶氮化合物,其以不同阳离子的单价、二价、三价或四价混合盐的形式存在,例如Ca2+,Na+,NH4+,NR4+,H+,Li+,K+,Mg2+,Ba2+,Sr2+,AI3+,Pb2+,Mn2+,Zn2+,Cr2+,Co2+,Fe2+,Fe3+,Zr4+和Cu2+,其中R为C1-C6烷基,比例任意选择。本发明还涉及公式(I)的钙盐,其具有两种晶体多态形式 - 红黄色和绿黄色,具有不同的性质,例如颜色色调或高温稳定性,以及这些化合物的制备和它们在有机材料的质量着色和蜡转印带、色调剂或彩色滤光片的生产中的应用。
