PLACING INTO INTERFACIAL CONTACT THE SURFACES OF AN IMAGE-RECEPTIVE ELEMENT AND AN ADDITION POLYMERIZABLE SOLID LAYER CONSISTING OF (1) UNDEREXPOSED AREAS IN SAID SOLID LAYER COMPRISING (X) AT LEAST ONE NON-GASEOUS ETHLENICALLY UNSATURATED COMPOUND CONTAINING AT LEAST ONE TERMINAL ETHYLENIC GROUP, HAVING A BOILING POINT ABOVE 100*C. AT NORMAL ATMOSPHERIC PRESSURE AND BEING CAPABLE OF FORMING A HIGH POLYMER BY PHOTOINITATED ADDITION POLYMERIZATION, AND (Y) A DIFFUSIBLE COLORANT THAT DIFFUSES AT A TEMPERATURE BELOW THAT AT WHICH SAID LAYER BECOMES TACKY AND ADHERENT TO BOND PAPER, AND (2) COMPLEMENTARY ADJOINING COPLANAR EXPOSED IMAGE AREAS COMPRISING AN ADDITION POLYMER OF THE AFORESAID COMPOUND AND SAID COLORANT, AND B. HEATING AT LEAST ONE OF THE ELEMENTS WHILE THEY ARE IN SURFACE CONTACT TO A TEMPERATURE SUFFICIENT FOR THE COLORANT TO DIFFUSE THROUGH THE UNDEREXPOSED AREAS OF THE LAYER BUT BELOW THAT AT WHICH THE LAYER BECOMES TACKY AND ADHERENT TO SAID IMAGE-RECEPTIVE ELEMENT WHEREBY THE COLORANT IN THE UNDEREEXPOSED IMAGE AREAS DIFFUSES AND TRANSFERS TO SAID ELEMENT.
