<P>PROBLEM TO BE SOLVED: To provide a method for preventing the pigment photo-fading of a hydrophilic substrate such as a food. <P>SOLUTION: This method for preventing the pigment photo-fading of the hydrophilic substrate is characterized by coating the hydrophilic substrate with an anti-oxidizing agent and then coating the coated hydrophilic substrate with the pigment. The anti-oxidizing agent has a solubility of 50 g/L (30°C) in hexane, and has a hue fading degree [ΔE value = (a hue after the irradiation of light) - (a hue before the irradiation of light)] of a hue after the irradiation of light to a hue before the irradiation of light of ≤5.3, when a fish paste is coated with the anti-oxidizing agent, then coated with a pigment, and finally irradiated with light at 3,000 luces for 48 hrs. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
