The present invention relates to a masterbatch comprising colorant particles, a polyol poly(hydroxy fatty acid) ester dispersing agent and a carrier resin. The masterbatch is used for coloring thermoplastic polymer compositions. The present invention also relates to a method for producing said masterbatch, a colored thermoplastic polymer composition comprising said masterbatch and colored thermoplastic products formed of said colored thermoplastic composition.

A process for producing a UV-stable laminated structure having thermal aging resistance includes coextruding the following layers in a single-stage operation, or laminating the following layers onto one another in a heatable roll nip:
a substrate layer made up of a graft copolymer and a styrene and/or (meth)acrylate/(meth)acrylonitrile copolymer, and optionally containing a polycarbonate and a fibrous and/or particulate filler; and
a transparent top layer of polymethyl methacrylate.
In another embodiment, an interlayer of e.g., impact-modified polymethyl methacrylate or polycarbonate, is coextruded or laminated between the transparent top layer and the substrate layer to produce a UV-stable laminated structure. An adhesion layer containing an adhesion promoter can be coextruded or laminated on the outer surface of the substrate layer.
A molding is produced by thermoforming the UV-stable laminated structure, which is advantageously backsprayed or back-cast with the substrate layer or a polyurethane foam. The molding can take the form of an automotive exterior bodywork component.

The invention relates to polyesters which contain carboxy groups and which are used as dispersing agents for pigment concentrates for the colouring of thermoplastics, and to a process for their preparation. The invention further relates to the use of the polyesters as dispersing agents, and also to masterbatches which comprise pigments, thermoplastics and the polyesters.
