Abstract
An image-receiving sheet material for forming a transfer image by heat-transferring an ink layer from a transfer material having a heat-transferable ink layer onto an image-receiving sheet material, and re-transferring the ink layer onto a permanent support. The image-receiving sheet material comprises a support having thereon at least two image-receiving layers, at least one of the image-receiving layers is transferred onto the permanent support, and at least the image-receiving layer onto which the ink layer is transferred contains a modified resin prepared from a polyvinyl acetal resin containing hydroxyl groups in which from 0.1 to 1 equivalent of the hydroxyl groups of the polyvinyl acetal resin have been converted to a group represented by formula (I). In a preferred embodiment, the image-receiving layer onto which the ink layer is transferred further contains a high molecular weight compound having at least a repeating unit represented by formula (II) and/or formula (III). In image forming method using the image-receiving sheet material, and a laminate comprising an image-receiving sheet layer and a heat transferable ink layer are also disclosed.
