されイ）。As a result, when printing is performed as a thermal transfer medium, the transfer of the heat-melting component occurs only partially, making it possible to repeatedly print on the same location. That is, the network structure generated by the polymerization of the polymerizable component increases the mechanical strength of the entire ink layer, and at the same time forms a path for the splitting transition of the heat-melting f1-component. It is speculated that the lumpy structure generated by the ink layer finely divides the layer of the heat-fusible component, creating non-uniformity in the ink layer against stress during transfer, and that these effects make the split transfer possible. stomach).
