PURPOSE:To markedly reduce trouble due to the generation of a curl even when recording-erasure is repeatedly performed and to enable many-time use. CONSTITUTION:In a recording sheet wherein a reversible thermal recording layer 1 based on an org. monomeric substance and a resin matrix is provided on a support 2, the heat shrinkage factor of the support 2 when the support is treated at 140 deg.C for 10min is below 1%. |
