Method for recording a multi-color image on a thermal recording material

Abstract

An image recording method for recording an image on a thermal recording material by developing colors by heating one or more times the thermal recording material having thermal color developing transparent layers in the form of triple layers which respectively develop different hues, the thermal color developing transparent layers in the form of triple layers being formed on one side of a transparent carrier thereof. The image recording method comprising the following steps of: selecting pixels to develop their colors in at least the outermost layer in accordance with the hue to be recorded; causing the outermost layer and an inner layer positioned next to the outermost layer to develop their colors for each of the pixels; subjecting the outermost layer to a fixing process; selecting pixels to develop their colors in at least an intermediate layer which has not developed its color; causing the intermediate layer and the inner layer than the intermediate layer to simultaneously develop their colors; and successively subjecting the intermediate layer to a fixing processes to the innermost layer. Therefore, a color developing layer in the form of a multiplicity of layers formed on either side of the transparent carrier can be simultaneously subjected to the heat treatment and the color deviation can thereby be prevented. Therefore, the working efficiency can be improved and energy required to complete the recording operation can be reduced.
