Patent number: 9982137Abstract: An alkali-resistant pigment composition is provided comprising (a) a C.I. Pigment Yellow 139 and (b) an adduct containing a compound of formula (II) or a tautomeric form thereof, wherein X is O, S or NR1; Y is O, S or NR1; the group -A-B— is selected from the group consisting of —CR2?CR3?, —CR4R5—CR6R7?, —CY—CR8R9?, —CX—NR10?, —CR11?N—, —CR12R13?NR14?and R1 is hydrogen, C1-C8alkyl, C3-C7cycloalkyl, C6-C10aryl or C7-C10aralkyl; R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13 and R14 are independently of each other hydrogen, halogen, C1-C8alkyl, C2-C8alkenyl, or C6-C10aryl, or R2 and R3 form a benzoannellated ring; and/or a melamine- or pyrimidine-based compound, which is optionally substituted. The pigment composition may be used as colorant in various applications, especially in coloring high molecular weight organic material, for example, coating compositions, paints, printing inks, liquid inks, plastics, films or fibers.Type: GrantFiled: August 14, 2015Date of Patent: May 29, 2018Assignee: BASF SEInventors: Philippe Bugnon, Karin Karrer, Jean Allaz

Patent number: 8772371Abstract: The invention relates to pearlescent pigments comprising a platelet-shaped substrate, a metal oxide coating comprising a metal oxide layer having a refractive index of greater than 1.8 and a protective layer, wherein the protective layer comprises a metal oxide/hydroxide layer and optionally boroxide, applied to which is an organic aftercoat of an acrylic copolymer, to a method for producing said pigments and the use thereof. The outer layer provides a very good photo-stabilisation of the TiO2 coated platelet-shaped substrates, such as mica, combined with a good water resistance and an anti-yellowing performance.Type: GrantFiled: April 28, 2009Date of Patent: July 8, 2014Assignee: BASF SEInventors: Philippe Bugnon, Karin Karrer, Patrice Bujard
