Trouble in use

Glue sticks :Why does receipt get blackened after gluing (Shiwa nashi PiT)

The heat-sensitive dye (leuco dye) used in the receipt is considered to have reacted black with the solvent. Wrinkle-free PiT might cause discoloration in thermal paper such as receipt and fax paper. For less discoloration effect, please use PiT HI-POWER or Kieiro PiT. Besides, the same phenomenon might occur with pressure-sensitive papers such as copy slips. Please do not use Shiwa nashi PiT on receipt, fax paper and other thermal paper.
