Title:
COLORING SHEET, COLORING ARTICLE, TRANSFER FOIL AND MANUFACTURING METHOD OF TRANSFER FOIL
Document Type and Number:
Japanese Patent JP2022026090
Kind Code:
A
Abstract:
To provide a coloring sheet, a coloring article, a transfer foil and a manufacturing method of a transfer foil, capable of absorbing transmitted beams while capable of enhancing interlayer adhesion.SOLUTION: A coloring sheet 10 includes a multilayer film layer 13 and an adhesion layer 14 abutting on the multilayer film layer 13. The multilayer film layer 13 is configured such that refractive indexes of neighboring layers in the multilayer film layer 13 are different from each other, and a light reflective index in a specific wavelength region of incident light on the multilayer film layer 13 is higher than a light reflective index in another wavelength region. A surface opposite to a face abutting on the adhesion layer 14 in the multilayer film layer 13 has a rugged structure. The adhesion layer 14 has absorbency of incident light. Light transmissivity of the adhesion layer 14 is 50% or less.SELECTED DRAWING: Figure 1
