    摘要: To provide a color-change laminate wherein a color tone derived from a porous layer is visually conceived in a dry state and a metallic lustrous color property visually conceived in a liquid-absorbed state of the porous layer caused by water application is excellent in luminance and which satisfies both of changing properties and decorative properties in the dry state and in the liquid-absorbed state.
    A color-change laminate comprising a support having a metallic lustrous color property and a porous layer provided on the surface of the support, wherein the porous layer comprises a low-refractive-index pigment having a refractive index ranging from 1.4 to 1.8 and a transparent metallic lustrous color pigment formed by coating a transparent core material with a metal oxide and/or a transparent metallic lustrous color pigment having a color-flopping property of changing a color tone depending on the viewing point all fixed onto a binder resin in a dispersed state, wherein an average particle diameter a of the transparent metallic lustrous color pigment and a thickness b of the porous layer satisfy the following expression (1): a ≧ 2 ⁢ b
    wherein the average particle diameter is an average particle diameter determined by a laser diffraction method, which is a particle diameter corresponding to 50% of cumulative distribution as a median diameter on the basis of volume.
