る。In recent years, canned beverages such as canned coffee have been produced after filling the can with coffee and printing necessary information such as the lot number and manufacturing date on the lid or bottom of the can using an inkjet recording method. It is sold after being heated and sterilized with steam in a heating sterilizer such as an autoclave. However, usually
Since a large number of can bodies are placed in the sterilizer, there is a possibility that not all the can bodies will be sufficiently heat sterilized. For thermal sterilization of surgical instruments, etc., for example, Japanese Patent Publication No. 5223
As described in Publication No. 24 and JP-A No. 61-123682, sterilization display paper made by coating paper with a thermochromic composition is placed in a sterilizer together with surgical instruments, etc., and the heating temperature is adjusted. However, because the amount of canned beverages produced is enormous, it is extremely difficult to attach sterilization display paper to each can and then peel it off from the can after sterilization. This is not only cumbersome, but also increases manufacturing costs.

共に、温熱加熱後の変色が明瞭でない。Therefore, a sterile indicating ink composition for inkjet recording which has a discoloration property when heated with heat was developed by Japanese Patent Publication No. 62-9148.
It is stated in the No. This ink composition is a composition in which a combination of a dye that can be extracted by water and a dye that cannot be extracted by water is dissolved in an aliphatic alcohol together with a resol resin, and when heated, the water-extractable dye is dissolved in water. Since discoloration occurs as a result of leaching, the prints have poor moisture resistance and are likely to smear, and the discoloration after heating is not clear.
