Abstract

The invention provides a thermosetting composition, a laminate, a substrate, a film, a display device and a window material. Provided is a thermosetting composition capable of producing a laminate having two layers by one film formation and for obtaining a laminate with a small haze value. A thermosetting composition characterized in that it comprises a fluorine-containing copolymer ( A) Composition of an aromatic ring-containing carboxyl compound (B), an aromatic ring-containing cyclic ether compound (C) and a solvent (D), and each component is contained in a specific amount.

Description

technical field [0001] The present invention relates to a cured film obtained by forming a thermosetting composition and a film. This cured film is a laminate having two layers formed by one film formation, and this laminate can be used as an antireflection substrate or an antireflection film, and can be used as various display devices. and anti-reflection films used in window materials. Background technique [0002] Now, with the development of multimedia, various developments occur in various display devices. In addition, in various display devices, especially in display devices used outdoors mainly in portable display devices, it is increasingly important to improve the visibility. Watch, this matter goes straight to a technical subject. [0003] Moreover, in various window materials, especially in window materials used under lighting and outdoors, centering on display window materials such as shops and vending machines, it is possible to reduce the reflection of light...
