Additive color imaging using a silverless recording element

A method for producing color transparent images of a multicolored object on a multilayered recording element which includes an additive color screen and a silverless imaging layer, such imaging layer being substantially insensitive and transparent to visible radiation and responsive to ultraviolet radiation incident thereon to become less transparent to visible radiation, said method comprising the steps of:

• (a) forming a monochrome image containing color information of the multicolored object on a panchromatic auxiliary recording element that is separate from said multilayered recording element and is substantially transparent to ultraviolet radiation in a pattern corresponding to image information, said image-forming procedure comprising the steps of illuminating the multicolored object with visible radiation and imagewise exposing the auxiliary recording element to the illuminated object, said imagewise exposure being effected through the multilayered recording element while the relative positions of the auxiliary and multilayered recording elements are substantially fixed;
• and
• (b) exposing the silverless imaging layer of the multilayered recording element to ultraviolet radiation, such exposure being effected through the monochrome image formed on the panchromatic auxiliary recording element while said auxiliary recording element and said multilayered recording element occupy substantially the same relative positions as occupied during said imagewise exposing step, whereby the color image information in the panchromatic auxiliary recording element is transferred to the silverless imaging layer of the multilayered recording element.
