Abstract

An image-receiving sheet comprising a base sheet and a receiving layer, provided on one surface of said base sheet, for receiving a dye or a pigment migrating from a heat transfer sheet, said base sheet comprising one or two or more layers, at least one layer of said base sheet having a porous structure or a foamed structure.

Claims

1. A process for heat transfer recording comprising the steps of:

providing (a) a heat transfer sheet and (b) an image-receiving sheet to be used in combination with the heat transfer sheet, said image-receiving sheet comprising a base sheet and a receiving layer provided on one surface of said base sheet for receiving a dye or a pigment migrating from a heat transfer sheet during said heat transfer recording, said receiving layer comprising a resin for receiving the thus migrated dye or pigment from the heat transfer sheet, said base sheet comprising a laminate of (i) a first layer comprising a foamed sheet of polyolefin or polyester and (ii) a second layer comprising a non-foamed plastic film, said first layer being disposed between said second layer and said receiving layer;

bringing the heat transfer sheet into contact with the receiving layer of the image-receiving sheet; and

carrying out heat transfer recording in accordance with information for printing, thereby transferring said dye or pigment to the image-receiving sheet.
