    • A process for mass-colouring high molecular weight material, in which process a compound of formula or a tautomer thereof, wherein M1 is H, ½M2, ⅓M3 or NR4R5R6R7, preferably H, ½M2 or NR4R5R6R7, especially H, M2 is an alkaline earth or transition metal in oxidation state II or an oxo-metal in oxidation state IV, M3 is Al(III), a transition metal in oxidation state III or an oxo-metal in oxidation state V, R1 is H or a non-ionic substituent, R2 is H or, independently of R1, a further non-ionic substituent, R3 is H, C1-C6alkyl, phenyl, CO—C1-C6alkyl or CO-phenyl, preferably H or CO—C1-C6alkyl, especially H, and R4, R5, R6 and R7 are each independently of the others H or phenyl, benzyl or C1-C6alkyl, which are unsubstituted or may be substituted by hydroxy or by halogen and in the case of C3-C6alkyl is uninterrupted or interrupted by O, is incorporated into the high molecular weight material before or during shaping. The colorations obtained have good light stability and thermal stability, especially in polyolefins.
    • 其中M1为H,1 / M2M2,IIIM3或NR4R5R6R7,优选为H,1 / M2或NR4R5R6R7,特别是H,M2的式或其互变异构体的化合物或其制备方法是碱土金属或 处于氧化态II的过渡金属或氧化态IV的氧代金属,M3是Al(III),氧化态为III的过渡金属或氧化态V的氧代金属,R1为H或非离子取代基, R 2是H或独立地是R 1,另外是非离子性取代基,R 3是H,C 1 -C 6烷基,苯基,CO-C 1 -C 6烷基或CO-苯基,优选H或CO-C 1 -C 6烷基,特别是H和R 4 R 5,R 6和R 7各自独立地为H或苯基,苄基或C 1 -C 6烷基,它们是未取代的或可被羟基或被卤素取代,并且在C 3 -C 6烷基的情况下不被中断或被O中断。 在成形之前或成型期间并入高分子量材料中。 获得的着色具有良好的光稳定性和热稳定性,特别是在聚烯烃中。
