High Resistance to Heat Exposure and High-Sensitivity Technology of RICOH Thermal Paper. Development of 130LHB.

RICOH CO, LTD has achieved high heat resistance by using a color former with high melting point that could not not be used before, and developed "High Protection Technology" which make heat resistance and high-sensitivity capable of coexistence. In this paper, history, principle of thermal paper, and high resistance to heat exposure and high-sensitivity technology are described. 1.
