Title:
可撓性調光シート
Document Type and Number:
Japanese Patent JP6771211
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a lighting control sheet which controls a light transmission color and light transmissivity of a sheet by a change in air temperature, adjusts a lighting environment with light transmittance of the sheet as the maximum in the daytime, when heat on a surface temperature of the sheet is accumulated up to high temperature under hot weather, in particular, exhibits a curtain effect for suppressing light transmittance, suppresses rise of the temperature in the inside by several degrees and exhibits a paper-covered lamp effect by indoor illumination at night, and is also excellent in weather resistance and flexibility.SOLUTION: A light transmitting laminate includes a surface protective layer and a rear face resin layer and a thermochromic resin layer in the middle portion, where at least the surface protective layer has semi-transmissive properties and ultraviolet shielding properties, the thermochromic resin layer contains reversible microcapsule A having a complete decolorizing point (°C) between normal temperature and 80°C and reversible microcapsule A having a complete coloring point (°C) between normal temperature and 80°C, and gradually decreases/increases the total light transmittance of the light transmitting laminate by setting the complete decolorizing point (°C) to be lower than the complete coloring point (°C).SELECTED DRAWING: Figure 1
