Rewritable indication label for recording medium, recording medium and recording medium case

Abstract

A rewritable indication device layer on which visible information is rewritably recorded and erased, is formed on a label base layer. A protection layer for protecting the rewritable indication device layer is formed on the rewritable indication device layer. The rewritable indication label for a recording medium having such structure, is adhered to a recording medium or a recording medium case.

What is claimed is  
     
         1 . 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.    
     
     
         2 . A rewritable indication label for a recording medium according to  claim 1 , wherein 
 a releasable sheet is provided through an adhesive layer on a side of the label base layer opposite to the rewritable indication device layer.    
     
     
         3 . A rewritable indication label for a recording medium according to  claim 1 , wherein 
 the rewritable indication device layer comprises a magnetic recording layer including microcapsules containing a liquid and flake magnetic fine particles.    
     
     
         4 . A rewritable indication label for a recording medium according to  claim 1 , wherein 
 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.    
     
     
         5 . A rewritable indication label for a recording medium according to  claim 1 , wherein 
 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.    
     
     
         6 . A rewritable indication label for a recording medium according to  claim 1 , wherein 
 the protection layer comprises a resin layer of a resin composition containing a synthetic resin as a main component of a vehicle.    
     
     
         7 . A rewritable indication label for a recording medium according to  claim 1 , wherein 
 a primer layer is provided between the rewritable indication device layer and the protection layer.    
     
     
         8 . A rewritable indication label for a recording medium according to  claim 1 , wherein 
 a primer layer is provided between the label base layer and the rewritable indication device layer.    
     
     
         9 . A recording medium with a rewritable indication label adhered to through an adhesive, 
 the rewritable indication label comprising: 
 a label base layer;  
 a rewritable indication device layer formed on the label base layer, on which visible information can be recorded and erased; and  
 a protection layer formed on the rewritable indication device layer, for protecting the rewritable indication device layer.  
   
     
     
         10 . A recording medium case with a rewritable indication label adhered to through an adhesive, the rewritable indication label comprising: 
 a label base layer;    a rewritable indication device layer which is formed on the label base layer and on which visible information can be rewritably recorded and erased; and    a protection layer formed on the rewritable indication device layer, for protecting the rewritable indication device layer.
