摘要 |
<p>To enhance the optical density of colours produced by thermal transfer printing, a dyesheet is used having an intermediate dye-barrier layer between the substrate and the dyecoat. This layer consists essentially of a reaction product of polymerising acrylic functional groups in a layer of a coating composition comprising: (a) an organic resin comprising at least one polyfunctional material having a plurality of pendant or terminal acrylic groups per molecule available for cross-linking, at least 50% by weight of the polyfunctional material having at least 4 such acrylic functional groups per molecule; and (b) at least one linear organic polymer soluble or partially soluble in the resin, and comprising 1-40% by weight of the resin/polmer mixture.</p> |
