MUMBAI, India, June 24 -- Intellectual Property India has published a patent application (202617064738 A) filed by Lanxess Deutschland Gmbh on May 22, 2026, for Electromobility Components.
Inventors include May, Lars; Jentsch, Joerg-Dietrich; and Kischkewitz, Marvin.
The application for the patent was published on June 12, 2026, under issue no. 24/2026.
Abstract: The present invention relates to electromobility components having a color difference ?E 20 to the L*a*b* coordinates and a color number beginning with "2" of the RAL color chart, containing polymer compositions on the basis of at least one polyamide and a colorant having an average particle size d50, determined according to ISO 13320 by way of laser diffractometry, in the range of 1 to 12 µm, containing 9,9'-oxybis-12H-phthaloperin-12-one, 9,10-oxybis-12H-phthaloperin-12-one and 10,10'-oxybis-12H-phthaloperin-12-one in a ratio of 1 :1 : 0.8 - 1.5 to 1 : 1.5 : 0.8 - 1.5. The invention also relates to the use of a colorant having an average particle size d50, determined according to ISO 13320 in the range of 1 to 12 µm, containing 9,9'-oxybis-12H-phthaloperin-12-one, 9,10-oxybis-12H-phthaloperin-12-one and 10,10'- oxybis-12H-phthaloperin-12-one in a ratio of 1 : 1 : 0.8 - 1.5 to 1 : 1.5 : 0.8 - 1.5 in polymer compositions for producing polyamide-based electromobility components having a color difference ?E 20 to the L*a*b* coordinates and a color number beginning with "2" of the RAL color chart, in particular in order to reduce colored streaks when producing polyamide-based electromobility components.
