A MIGRATING DYE INDICATOR WHEREIN THE IMAGE PRODUCED HAS REDUCED BLURRING

摘要

A migrating dye indicator that includes a display layer (10) and a base substrate layer (20). An adhesive layer (40) is on one surface of the display layer (10) for adhesively attaching the display layer (10) to the base layer (20). The base layer (20) includes a migrating dye (50) capable of migrating through the adhesive layer (40) to the display layer (10) when the adhesive layer (40) is placed in contact therewith. The adhesive layer contains an accelerator for enhancing the migration of the dye through the adhesive layer. The base layer (20) contains a means for absorbing the accelerator into the base layer (20).
