METHOD FOR PRODUCING EFFECT PIGMENTS

Resumen de: US20260357071A1

A process for creating effect pigments involves providing a donor film with a relief structure. A reflective layer is applied to this relief structure. An acceptor film with an adhesive layer on one side is also prepared. The process forms a first-layer composite by laminating the acceptor film's adhesive layer onto the reflective layer on the donor film's plateau surfaces. When the donor film is peeled away, the reflective layer remains on the lowered regions and flanks as a residual layer, while the acceptor film captures pieces of the reflective layer from the plateau surfaces. These pieces are then detached to form effect pigments, with their shape determined by the relief structure. To facilitate this, the relief structure is pretreated to reduce adhesion, such as by loosening the adhesive or applying a release agent, enabling pigment pieces to detach while maintaining the adhesive layer on the acceptor film.
