Title:
NANOSHEETS, COATING LAYER FORMING COMPOSITION USING SAME, AND MOLDED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2024/080286
Kind Code:
A1
Abstract:
The present invention provides: nanosheets which have been surface treated with a silane compound such as polyether-modified silane; a dispersion thereof; and a hardcoat protective film for decorative films. This problem is solved by the following. Coated nanosheets that are coated with polyether-modified silane, that have a surface having a length of 0.1-10 μm, and that have a thickness of 0.5-5.0 nm. A dispersion of coated nanosheets in which coated nanosheets are a dispersoid and in which water or an organic solvent is a dispersion medium. A coating layer forming composition comprising: coated nanosheets; and a thermosetting resin and/or a photocurable resin. A molded article that is a laminate of: a coating layer including a coating layer forming composition; a decorative layer or a decorative layer joined to an adhesive layer; and a base material. A freestanding film comprising: coated nanosheets; and a thermosetting resin and/or a photocurable resin. Methods for producing the nanosheets and the molded article.
