Abstract
Abstract An image-receiving for use in combination with a heat transfer sheet has a substrate, an image-receiving layer provided thereon, and optionally a layer of a mold releasing agent provided on at least a part of the image-receiving layer. This image-receiving sheet exhibits good mold releasability and also provides a colored image having a high density, resolving power and continuous gradation.
