PURPOSE: To present various thermochromism aspects by a combination wherein discoloration properties synchronize with each other or the discoloration properties are different from each other, by a method wherein microcapsule pigments in which a crystalline compound to be selected out of esters, ethers and ketones is involved is comprised by being stuck to the inside of resin under a dispersed state. CONSTITUTION: A desired laminated body 1 is produced by laminating an upper thermochromism layer 3 to the upper layer of a thermochromism glare protection-light transmission printed or coated layer 2 presenting tautomerization properties of both states of a white opaque state and colorless transparent state by a temperature change wherein a microcapsule pigment whose particle involving at least one kind or two kinds out of crystalline compounds to be selected out of esters, ethers and ketones having the melting point within a range of -40 to +90 deg.C has a diameter of 0.1-50μm is comprised by being stuck to the inside of resin under a disperesed state. The microcapsule pigments present a hysteresis width depending on a particle diameter of the microcapsule and in a series whose mean particle diameter is less than 1-2μm, hysteresis width is taken as larger one as compared with the series whose particle diameter is at least 2μm. |
