<P>PROBLEM TO BE SOLVED: To provide a water color-changeable laminate in which a colored layer arranged in the lower layer of the porous layer is clear, which is rich in practicality that can express superior color-change that lasts long by application of water without ruining the function that can visually check a clear and plain image by colored layer even if water is repeatedly applied. <P>SOLUTION: The water color-changeable laminate includes on a support 2: a colored layer 3 containing colorants; and a porous layer 4 in which the low refractive index pigment is fixed to the binder resin to the dispersed state and the transparency is different in the liquid absorbed state and the non-liquid absorbed state. In the water color-changeable laminate 1, the colorants included the colored layer are either the water-insoluble disperse dye or the oil soluble dyestuff. <P>COPYRIGHT: (C)2013,JPO&INPIT |
