摘要:
The invention relates to inkjet ink, which when printed exhibits a clear, yellow colour, corresponding to azomethine dyes and whose lightfastness and dark stability corresponds to the level of phthalocyanines. Said yellow dye is obtained by using a salt of a quinophthalone of formula (I) as yellow dye wherein X represents COOH or SO3H.
