ABSTRACT:
A method of applying a dye image to a plastic member and the image bearing member thereby formed. A disperse dye having a melting point which is below the thermal deflection temperature of the plastic of the member and a vaporization point which is above said deflection temperature is applied to a surface of the member in a desired image. The dye bearing plastic is then heated to a temperature which is above the melting point of the dye and below the thermal deflection temperature of the plastic, but which is nevertheless high enough to cause some softening of said plastic. The dye is then permitted to diffuse into the plastic to provide a sharp, clear and durable image thereon.
