The photochemically induced change of colour of dyes derived from copper‐(II)‐phthalocyanine in presence of certain nitrogen‐containing crease‐resist resins was investigated by means of optical and electronspinresonance spectroscopy and by photo‐potentiometric methods. It is shown to be due to a light induced reversible one‐electron reduction of the copper (II)‐phthalocyanine.
