Abstract: A process for preparing colorants of the general formula (Ia), (Ib) or (Ic) or mixtures thereof, comprises reacting (a) tetracarboxylic acids or their functional derivatives with (b) at least one compound selected from i. aliphatic amines, ii. aromatic amines, iii. aliphatic diamines, iv. aromatic diamines, (c) optionally in the presence of further additives, (d) optionally in the presence of wetting agents in a mixing apparatus. These colorants are useful for coloration of macromolecular organic and inorganic materials of natural and synthetic origin.

Abstract: A process for preparing perylene pigments of the general formula (Ia) or (Ib) or mixtures thereof, by reacting perylenetetracarboxylic acids or functional derivatives thereof with aromatic diamines, where R1, R2 may be the same or different and may each independently be phenylene, naphthylene or pyridylene, where R1, R2 may each be mono- or polysubstituted by C1-C22-alkyl, C3-C22-alkenyl, C1-C22-alkoxy, hydroxyl and/or halogen, X1, X2, X3, X4, X5, X6, X7, X8 may be the same or different and may each independently be hydrogen or halogen, wherein the reaction is performed in the presence of a secondary or tertiary amine in an aqueous reaction medium.

Abstract: The invention relates to processes for preparing polymer compositions by means of preparations of nanoparticulate IR absorbers, and also to polymer compositions thus prepared. Uses of these polymer compositions, as for example in heat management or in agriculture, more particularly as greenhouse films, are likewise provided by the invention. Additionally provided by the invention are shaped articles, more particularly films, comprising such polymer compositions.

Abstract: Isoindoline pigments of the general formula I in which the variables are defined as follows: R1 is C1-C4-alkyl; R2 is hydrogen or C1-C4-alkyl, whose value expressing ease of dispersion in LDPE is ?10 and which require a reduction ratio of ?5 to obtain ? of standard depth of shade.

Abstract: Multilayer moldings (1) comprising an outer layer (2) comprising a thermoplastic polymer and at least one nanoscale IR absorber (8), and also an inner layer (3) arranged under the outer layer (2) and comprising a thermoplastic polymer. Multilayer molding (1) where the following are used as additional additives: UV absorbers, non-particulate organic IR absorbers, stabilizers, antioxidants, colorants, inorganic salts, pearl-luster pigments, NIR-reflective substances, antifogging agents, or fillers. Multilayer moldings (1) taking the form of a panel or sheeting. Process for the production of a multilayer molding (1) via coextrusion of the outer layer (2) and of the inner layer (3). Use of multilayer moldings in heat management, in agriculture, as window constituent, or as constituent of panels having cavities, twin-web panels, multi-web sandwich panels, or solid panels.
