(57) [Abstract] [Purpose] The thermal transfer method that uses only area gradation has excellent recording sensitivity, dot quality, gradation reproducibility, no stickiness and sticking phenomenon, and less humidity dependency of recording sensitivity, which is similar to printed matter. Provided are an image-receiving sheet material for heat-sensitive transfer recording capable of achieving formation of a good multi-gradation and high-quality color image quality, and a transfer image forming method using the same. An image-receiving sheet material used for forming a transferred image, comprising transferring an ink layer from a transfer material having a heat-transferable ink layer onto an image-receiving sheet material and then re-transferring it onto a permanent support, wherein the image-receiving sheet material is The support has at least two image-receiving layers, at least one of the image-receiving layers is transferred to a permanent support, and the image-receiving layer to which at least the ink layer is transferred is at least one of the hydroxyl groups in the polyvinyl acetal resin. It contains a resin in which 1 to 1 equivalent is converted to a group represented by the following general formula (I). -OW (I) |
