INK COMPOSITION FOR DISPLAY OF HIGH-PRESSURE STEAM STERILIZATION

摘要

PROBLEM TO BE SOLVED: To provide an ink composition for display of high-pressure steam sterilization useable when heat volume of the contents packed in a container is small, or when confirming that necessary heat treatment is carried out by applying printing or mark to a display plate attached to a basket for heat sterilization, capable of confirming that heat sterilization treatment is carried out by an imaging test apparatus in which ink is decolored by a prescribed heat sterilization treatment and display plate for a high-pressure steam sterilization in which display is applied by the ink composition.

SOLUTION: The ink composition for display of high-pressure steam sterilization comprises (A) 0.5-5 wt.% triphenylphthalide dye, (B) 0.4-5 wt.% organic amine coupler and (C) 20-40 wt.% binder resin having ≥80°C softening point.
