Abstract: A process for concentrating light by means of fluorescent compounds of the formula (I) where the R1's independently of one another are ortho-substituted aromatic or heterocyclic radicals which do not contain groups which confer solubility in water, and novel perylene-3,4,9,10-tetracarboxylic acid diimides of the formula I, where R1 is A1 and A2 being hydrogen, or one of A1 or A2 being isopropyl and the other being hydrogen. The compounds I are very lightfast and convert incident light into fluorescent light with high efficiency.

Abstract: A process for drying finely divided pigments contained in a press cake or a suspension, wherein a mixture of the pigment and a liquid whose critical temperature is below the decomposition temperature of the pigment is heated under pressure to above the critical temperature of the liquid and is then released while keeping the temperature above the dew line of the liquid. The process gives fine pigments powders which are easily dispersible in the media in which pigments are used, and which produce deep, brilliant colorations.

Abstract: The parent patent describes the use of anthraquinone dyes of formula (I): (in which R1 is H, Cl, Br or 1-4C alkylamino; R2 is H, Cl or Br; R3 is H or OH) for transfer printing. This addition claims the use of 1,4-dihydroxy anthraquinone (Ia) for the same purpose.
