AI Technical Summary

Technical Problem

Existing edible inkjet inks suffer from photochromic and light-fading issues in printed images, failing to effectively improve lightfastness.

Method used

Edible inkjet inks that use Red No. 3 and hydroxy acid salts with more than two carboxyl groups as color-changing inhibitors suppress the photodecomposition of Red No. 3 by adding citrate or malate to the ink.

Benefits of technology

It effectively suppresses light-induced color changes and fading of printed images, improves the lightfastness of edible inkjet inks, and ensures the tonal stability of printed images.
