PROBLEM TO BE SOLVED: To provide a reversibly thermal-discoloring hologram laminate capable of visually sensing the hue effect due to the color change of the hologram image and a reversibly thermal-discoloring layer from both upper and under sides thereof and capable of being adapted even to a shape article visually confirmed from many directions, and flat yarn using it. SOLUTION: The reversibly thermal-discoloring hologram laminate is constituted by respectively laminating transparent hologram layers on the upper and under surfaces of the reversibly thermal-discoloring layer being an intermediate layer. The reversibly thermal-discoloring layer or the reversibly thermal-discoloring layer constituted by laminating a transparent resin layer on either one of the transparent hologram layers contains a microcapsule pigment including a reversibly thermal-discoloring composition composed of an electron donating color forming organic compound, an electron accepting compound and an organic compound medium for reversibly causing the color reaction of both compounds. The flat yarn is obtained by narrowly cutting the reversibly thermal-discoloring hologram laminate. COPYRIGHT: (C)2006,JPO&NCIPI
