METHOD FOR MANUFACTURING MULTI-COLOR HEAT-SENSITIVE RECORDING MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing capable of manufacturing a method for manufacturing a multi-color heat-sensitive recording member capable of recording a plurality of colors by one recording member without necessity of preparing a plurality of printing units or a plurality of recording media and having good printing quality without color mixing like dichroic color developing paper at a low cost. SOLUTION: The method for manufacturing the multi-color heat-sensitive recording member comprises the steps of forming a first heat-sensitive color developing layer 3 on a support 2, then forming a desensitized region 4 processed to disable or dull a color developing capability of a part of the layer 3, and thereafter forming a second heat-sensitive color developing layer 5 for coloring in a different color from that of the first layer 3 on the region 4.
