Abstract
Abstract The present invention describes a self-responding laminated body in which an isotropic solution, wherein a polysaccharide derivative, dissolved in water, aggregates to demonstrate cloudy scattering due to a rise in temperature resulting in a decrease in optical transmittance, is sealed in a cell, of which at least a portion is transparent, that enables the aqueous solution to be viewed directly; wherein, the isotropic aqueous solution is a solution in which 100 parts by weight of a polysaccharide derivative, having a weight average molecular weight of roughly 10,000 to roughly 200,000, is dissolved in roughly 110 to roughly 2,000 parts by weight of a water-based medium composed of an amount of water that is roughly 25 to roughly 450 parts by weight with respect to 100 parts by weight of the polysaccharide derivative, and an amphipathic substance. This laminated body can be produced by sealing the isotropic aqueous solution in a cell having at least one transparent portion that enables the aqueous solution to be viewed directly, and can be advantageously used as a window.
