CHEMICAL HEAT AMPLIFICATION IN THERMAL TRANSFER PRINTING ABSTRACT Chemical heat amplification is provided in thermal transfer printing, wherein some of the heat necessary for melting and transferring ink from a solid fusible layer in a ribbon to a receiving medium is provided by an exothermic reaction. This chemical reaction is due to an exothermic material that is located in the ink layer, or in another layer of the ink bearing ribbon. The exothermic reaction reduces the amount of the input power which must be applied either electrically or with electromagnetic waves. Examples of suitable exothermic materials are those which will provide heat within the operative temperature range of the ink, and include nonaromatic azo compounds, peroxides, and strained valence compounds, such as monomers, dimers, trimers of the type which change their chemical bonding when they decompose to either a valence isomer or break into a number of molecular species.
