Title:
MICROCAPSULE AND FILM
Document Type and Number:
WIPO Patent Application WO/2019/065068
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a microcapsule having excellent quantum yield and durability; and a film containing the microcapsule. The microcapsule according to the present invention contains a core substance and an outer shell layer that covers the core substance, wherein the core substance contains quantum dots and a dispersion medium that has a liquid form at 25°C, the material for the outer shell layer is at least one resin selected from the group consisting of a urea-based resin, a melamine-based resin, a polyurethane-based resin, a polyurea-based resin, a polyamide-based resin and a copolymer resin composed of at least two of these resins, the core substance has a radius of 10 nm to 10 μm inclusive, the outer shell layer has a thickness of 5 nm to 9 μm inclusive, and the ratio of the thickness of the outer shell layer to the radius of the core substance is 0.50 to 0.90 inclusive.
