PURPOSE: To provide a secret patterned decorated article, the hiding properties of the secret patterned part of which is high when color is developed and the pattern made under the secret patterned part of which is clearly seen when the color is vanished even when reversible heat-sensitive discoloring layer having the comparatively bright color such as red, pink or the like is used. ;CONSTITUTION: In the secret patterned decorated article 5, in which non- discoloring background colored layer 2 is formed on the surface of base material 1 and then non-discoloring secret pattern layer 3 is locally formed on the background colored layer 2 and finally reversible heat-sensitive discoloring layer 4 is formed so as to cover both the background colored layer 2 and the secret pattern layer 3, the color I of the secret pattern layer 3 seen through the reversible heat-sensitive discoloring layer 4 under color vanished state and the color II of the background colored layer 2 seen through the reversible heat-sensitive discoloring layer 4 satisfy the following equation: b* of the color I≥b* of the color II...(1), |a* of the color 11|+|b* of the color II|≥30...(2), L* of the color I≤L* of the color II.;COPYRIGHT: (C)1995,JPO
