    摘要: A temperature sensitive material and method of preparing the same includes an oil-in-water emulsion in which the emulsifier type and content are controlled, as are the freezing point of the oil phase, the freezing point of the water phase, the oil-to-water ratio and the particle size of the oil phase and to which additives are introduced in the water phase, selected from the group consisting of a salt, glycerol and urea such that the material undergoes an irreversible optical change when subjected to a temperature above the reveal temperature of the emulsion.
