Abstract
Process for the simultaneous application of at least two molten, thermoreversible organogel layers to a substrate. The organogel layers can optionally contain dispersed additive ingredients, such as pigments. The organogel layers are coated onto a suitable substrate and then rapidly cooled or chilled to form a gel. Residual solvent is then removed. Multilayer coated films are thus formed with minimal interlayer mixing or interlayer diffusion of the additive ingredients.
