An object of the present invention is to provide an image receiving layer (3) which alliveates or substantially dissolves at least one problem selected from a low quality of the image such as glossiness and sharpness, a low preservative property of the image such as heat resistance, and a high running cost. Moreover, an object of the present invention is to provide a thermal transfer recording image receiver (1) having such image receiving layer (3). To achieve the objects, the present invention provides a image receiving layer (3) for a thermal transfer recording image receiver (1) having a substrate (2) and the image receiving layer (3) characterized in that the image receiving layer (3) is formed from a composition comprising an acrylic polyol resin and other thermoplastic resin. Further, the present invention provides such thermal transfer recording receiver (1) having the image receiving layer as well as a thermal transfer recording method using the receiver.

A transfer member includes a dyeing layer transfer member, which has a lubricating heat-resistant layer on the reverse surface of a first base material and laminated layers of a parting layer and a dyeing layer on the obverse surface, an ink transfer member, having a lubricating heat-resistant layer on the reverse surface of a second base material and the laminated layers of an adhesive layer and an ink layer, an intermediate member having a functional layer on a third base material, and an image-receptor. A thermal transfer printing method includes the steps of thermally transferring the dyeing layer onto the functional layer by setting a thermal head in contact with the lubricating heat-resistant layer of the dyeing layer transfer member, thermally transferring dye of the ink layer onto the dyeing layer that was transferred onto the functional layer in response to picture signals by setting the thermal head in contact with the lubricating heat-resistant layer of the ink transfer member, and thermally transferring the dyeing layer recorded with the: dye onto the main surface of the image-receptor. Thus, pictorial images of high quality are formed on the image-receptor, and thermal transfer printing can be carried out repeatedly and stably.

The present invention is directed to a thermal transfer printing process comprising:heating a thermal ink film with a printing head to print dye transferring images onto an intermediate sheet which comprises a substrate and a printing layer thereon,heaping an image receive sheet on said printing layer, andtransferring said printing layer onto the image receive sheet by pressure or heat;an improvement residing in that said printing layer is formed from polyvinyl acetal.The present invention also provides an intermediate sheet for the above thermal transfer printing process comprising a substrate and a printing layer on said substrate wherein said printing layer is formed from polyvinyl acetal.
摘要:
Dye-receiving sheets for heat transfer recording comprising on a substrate, a dye-receiving layer consisting essentially of a cured product of an acrylate having two acrylic or methacrylic unsaturated bonds. The sheet is used in combination with a dye transfer sheet comprising a sublimable dye, and has a high affinity for the dye and a high heat resistance without bleeding of the dye.
摘要:
Color sheets for thermal transfer printing comprise a substrate having a colorant layer on one side of the substrate and a resin layer formed on one side of the substrate and a resin layer formed on the other side of the substrate, the resin layer being made of a resin composition comprising fine particles and a lubricating material dispersed in a binder resin. The resin layer is made rough on the surface there of due to the presence of the fine particles whereby the color sheets do not stick to thermal heads and the resulting images are free of dropout defects and good in quality.
