Claim 1
Independent Claim
135 words
A PROCESS OF PRODUCING A RECORDING IMAGE BY MEANS OF A HEAT-SENSITIVE MATRIX SHEET HAVING A HEAT-SENSITIVE SIDE ON WHICH IS COATED A HEAT-SENSITIVE LAYER COMPRISING A POLYMER-CONTAINING THERMOPLASTIC MATERIAL IN A NONTACKY STATE OF AT LEAST PARTIAL CRYSTALLIZATION AND HAVING AN ORIGINAL TACKIFYING TEMPERATURE ABOVE 50*C. AT WHICH ORIGINAL TACKIFYING TEMPERATURE SAID THERMOPLASTIC MATERIAL WILL UNDERGO TRANSITION TO AN ESSENTIALLY NON-CRYSTALLINE STATE HAVING A SUBSTANTIALLY REDUCED TACKIFYING TEMPERATURE, SAID MATERIAL HAVING THE PROPERTY OF REMAINING FOR A SUBSTANTIAL PERIOD OF TIME AFTER SAID TRANSITION IN A STATE HAVING A REDUCED TACKIFYING TEMPERATURE AND HAVING THE PROPERTY IN SUCH STATE OF BEING TRANSFERABLE BY PRESSURE AT A TEMPERATURE ABOVE SAID REDUCED TRACKIFYING TEMPERATURE AND BELOW SAID ORIGINAL TACKIFYING TEMPERATURE, SAID PROCESS COMPRISING THE STEPS OF (1) PREFERENTIALLY HEATING ONLY IMAGE AREAS ON SAID HEAT-SENSITIVE LAYER
