Japanese Patent JP2023088305

A

To provide a method for manufacturing a structural color-variable sheet that can express different structural colors by changing its shape, and can maintain its shape and different structural colors.SOLUTION: The method for manufacturing the structure color-variable sheet 1 includes a preparation process, an uncured sheet making process, and a semi-cured sheet making process. In the preparation process, a resin composition in which particles 4 are uniformly dispersed is prepared by blending the particles 4, the average particle diameter of which is between 50 nm and 500 nm or less as calculated from the particle size distribution measured by the centrifugal sedimentation method by frequency, and the coefficient of variation of which is 20% or less as calculated from the particle size distribution, and a curable component 5. In the uncured sheet making process, the resin composition is processed into a sheet shape to make an uncured sheet 7. In the semi-cured sheet preparation process, the uncured sheet 7 is subjected to thermal energy and/or light energy to semi-cure the uncured sheet 7, thereby producing a semi-cured sheet 1 that is the structural color-variable sheet 1.SELECTED DRAWING: Figure 1
