Abstract: A transmit coil arrangement for a magnetic resonance device includes a plurality of individually actuatable conductor loops following one after another in a peripheral direction and a longitudinal direction on a cylinder surface. At least two groups, at a distance from one another in the peripheral direction, of at least two conductor loops following one after the other in the longitudinal direction are provided in the peripheral direction. To decouple the at least two groups, each of the at least two groups is bounded at least in the peripheral direction by at least one screen surface extending essentially in a radial direction and the longitudinal direction.

Abstract: The present invention relates to novel yellow anionic dyes, a process for their preparation, certain novel intermediates necessary for their preparation and the use of these dyes for dyeing natural or synthetic materials, in particular, paper. The dyes are of formula (14), (15) or (16) in which R1 represents hydrogen, C1-C4alkyl, C1-C4alkoxy or SO3H, R2 represents SO3H or CO2H, R3 represents hydrogen, C1-C4alkyl, halogen, hydroxy, C1-C4alkoxy, carboxy, NH2 or NHC1-C4alkyl, R3a represents hydrogen or NH2 and A1 and A2, independently of the other, is selected from the group consisting of an acetoacetylated amine, a derivative of barbituric acid, a 2,4,6-triaminopyrimidine derivative, a pyridone derivative, an aminopyrazole or a pyrazolone derivative and a benzoic acid derivative, or A1 and A2, each one independently of the other, represent a certain phenol residue.
