Do not exhibit the rainbow color having the polymer particles in the primer layer in the film

摘要

The present invention is primarily cross-linked by the base layer and the carbodiimide thermosetting polyesters, relates to an optical transparent film from the primer layer consisting of a blend of polyester and polymethyl methacrylate. The base layer preferably has an outer layer having an organic and / or inorganic particles are not core layer and a polyester containing no particles. The primer layer is preferably applied to the base layer from a solution that does not use an organic solvent. Composite material composed of the primer layer and the base layer is mainly being laminated with a protective layer of an acrylic polymer to form a solar control film. The various layers of the solar control film, sometimes contain functional additives such as UV light shielding agent. The primer layer, in particular, the polymethyl acrylate in the primer layer in combination with cross-linking by carbodiimide exhibits iridescent luster solar control film having a polyester base coated with an acrylic was significantly reduced. Adhesion between the layer and the polyester layer of the solution acrylic coated from organic solvents, has durability in moist and warm conditions of use.FIELD 2
