Abstract

PURPOSE:To provide a sheet having excellent color fading effect due to the expansion of a heated portion and forming a visible image comprising forming a coloring layer containing a heat expansible component and a binder on a surface of a support sheet. CONSTITUTION:On (A) a surface of a support sheet, (B) a coloring layer (a thickness is pref. 0.01-0.1mm.) containing (a) a heat expansible microcapsule (e.g.; a shell component is a thermoplastic resin such as a polyacrylate and a gas generating substance in an interior thereof is propane or the like) and (b) a binder (e.g.; vinyl acetate or an acrylate) and being compounded with a dyestuff or a pigment is formed to obtain an objective sheet. Moreover, the component (a) pref. has a heat expansion temp. of 120-130 deg.C, a particle size in an unexpanded condition of 30mu or less and a expansion degree of 3-5 times and the component (b) is pref. compounded in an amount of 200-400pts.wt. against 100pts.wt. of the component (a). Further, a heat softenable coloring coating may be formed on the layer containing a component (a) and (b) to form a coloring layer.
