Abstract: This invention relates to a process for printing hydrophobic fiber materials with disperse dyes, which comprises 1) dyeing or printing the fiber materials overall with a disperse dye, and 2) printing the fiber materials in areas with a printing paste, which comprises as component (A), at least one cationic assistant, as component (B), at least one polyethylene glycol, as component (C), at least one nonionogenic detergent and, optionally, as component (D), at least one disperse dye, it being possible for steps 1) and 2) to be carried out in any sequence and for step 2) to be carried out repeatedly without using any dye, or using different dyes, and, if necessary, drying the fiber material thus treated and then fixing the dye on the fiber material by heat treatment. The novel process affords multicolored prints having sharp contours and very good fastness to hot light.

Abstract: Hindered amines substituted on the N-atom with an —O—E—OH moiety are particularly effective in stabilizing polyolefin and automotive coating compositions against the deleterious effects of oxidative, thermal and actinic radiation where the presence of the OH group on the compounds adds important properties not attainable by the use of normal —O—E moieties.

Abstract: A stir-in pigment composition for coloring high-molecular-weight material, particularly coatings and ink systems, comprises 85 to 99.5 parts by weight of a pigment and 0.5 to 15 parts by weight of an additive comprising a vinylpyrrolidone polymer or copolymer. The stir-in pigment composition is in the form of microgranules and is obtainable by spray drying a high solids content aqueous pigment dispersion containing the pigment and the additive. The new pigment composition powders are easily handled, easily wetted and disperse rapidly to form homogeneous aqueous pigment dispersions which are practically free of larger pigment aggregates and can readily be incorporated into aqueous ink and paint systems as stir-in pigments without a dispersion step in a bead mill.
