摘要:
There is provided a rewritable indication label for a recording medium to be adhered to the recording medium comprising:
a label base layer; a rewritable indication device layer provided on the label base layer, on which visible information can be rewritably recorded and erased; and
a protection layer provided on the rewritable indication device layer, for protecting the rewritable indication device layer, the rewritable indication device layer comprises a heat-sensitive recording layer of a resin composition which is changed by heat reversibly from a transparent state to an opaque state and can retain the transparent state and the opaque state at a normal temperature.
There is further provided a rewritable indication label for a recording medium to be adhered to the recording medium comprising:
a label base layer; a rewritable indication device layer provided on the label base layer, on which visible information can be rewritably recorded and erased; and a protection layer provided on the rewritable indication device layer, for protecting the rewritable indication device layer, the rewritable indication device layer comprises a heat-sensitive recording layer containing a leuco dye, and is colored by heat and erased by action of an erasing chemical agent.
