Claim Text:
1. A method of forming a color laser image that is observable with varying colors, from an assembly comprising a protective layer protecting pixels comprising color subpixels and a laserable layer, the assembly being laminated on a reflective white medium, the method comprising: carbonizing the laserable layer in part by the effect of a laser beam in order to form non-reflective, black volumes in association with the color subpixels in order to produce gray levels of a personalized color laser image when the personalized color laser image is observed perpendicularly to its plane, and when the personalized color laser image is observed under various angles of incidence, the non-reflective, black volumes mask adjacent subpixels, thereby causing changing colors in the personalized color laser image to appear to an observer.
