<P>PROBLEM TO BE SOLVED: To provide a reversible thermochromism stationery set which is highly convenient in that a reversible thermochromism stationery capable of keeping memory as to states before/after discoloration, can be thermally discolored easily by frictional heat of a friction material. <P>SOLUTION: This reversible thermochromism stationery set 1 is constituted of the following components: (1) Reversible thermochromism stationery 2 with a reversible thermal discoloration layer containing a reversible thermochromism material showing color memory properties i.e. at 40 to 90 deg.C of complete color erasing temperature t4 and at not more than 10 deg.C of complete color development temperature t1, formed on the surface of a stationery made up of cloth and leather, and (2) the friction material 5. <P>COPYRIGHT: (C)2013,JPO&INPIT |
