Phthalocyanine (PC) has high weather resistance and shows near-infrared light emission in the molecular dispersion state, so it is expected to be applied for anti-counterfeit ink. In order to improve the dispersibility in the toner resin, PC derivatives having substituent groups have been developed, however, there were issues that the complications of the synthesis procedure and the low chemical and thermal stability of the substituents. In this report, we report that PC derivatives can be adsorbed on inorganic nanoparticles and dispersed in resin to maintain the fluorescence emission state of PC derivatives.
