Claims (14)
- A re-transfer intermediate sheet for thermal transfer printing of an article by thermal retransfer, comprising a supporting substrate having on one side an imageable layer and on the other a backcoat, wherein the backcoat is a heat-resistant layer comprising a polymeric binder and a protective particulate filler, characterised in that the protective particulate filler is included in an amount of at least 100% by weight of the binder.
- A method of printing an article having a dye-receptive surface comprising the steps of pressing together a dye-donor sheet and an imageable layer of a retransfer intermediate sheet comprising a supporting substrate having on one side the imageable layer and on the other a backcoat, forming an image in the imageable layer by thermal transfer printing, pressing the thus-formed image-containing layer against the dye-receptive surface of the article, and applying heat to the intermediate sheet to effect retransfer of the image to the dye-receptive layer of the article, wherein the backcoat is a heat-resistant layer comprising a polymeric binder and a protective particulate filler, characterised in that the protective particulate filler is included in an amount of at least 50% by weight of the binder.
- A retransfer intermediate sheet according to claim 1, wherein the protective filler mainly comprises particles of 1-10µm mean diameter.
- A retransfer intermediate sheet according to claim 3, wherein the protective filler mainly comprises organic particles.
- A retransfer intermediate sheet according to claim 4, wherein the organic particles comprise a poly(alkylsilylsesquioxane).
- A retransfer intermediate sheet according to claim 3, wherein the protective filler mainly comprises inorganic particles.
- A retransfer intermediate sheet according to claim 3, wherein the backcoat composition contains the protective filler in an amount of at least 200% by weight of the binder.
- A retransfer intermediate sheet according to claim 3, wherein the backcoat composition contains the protective filler in an amount of 100% to 250% by weight of the binder.
- A retransfer intermediate sheet according to claim 1, wherein the heat-resistant layer contains an anti-blocking agent comprising particles of 8-15µm mean diameter, in an amount of 10-25% by weight of the binder.
- A retransfer intermediate sheet according to claim 1, wherein the backcoat composition contains a metal phosphate salt of stearic acid in an amount of from 1 to 20% by weight of the binder.
- A retransfer intermediate sheet according to claim 1, wherein the binder is a cellulosic resin.
- A retransfer intermediate sheet according to claim 1, wherein the polymeric binder is cross-linked.
- A retransfer intermediate sheet for thermal transfer printing of an article by thermal retransfer, comprising a supporting substrate having on one side an imageable layer and on the other a backcoat, wherein the backcoat is a heat-resistant layer comprising a polymeric binder and a protective particulate filler, characterised in that the protective particulate filler is selected from poly(alkylsilylsesquioxane) compounds and hydrated alumina fillers in an amount of at least 100% by weight of the binder.
- A retransfer intermediate sheet according to claim 12, wherein the protective filler comprises poly(methylsilysesquioxane) particles of 1-10µm mean diameter.
