- the average particle size of the organic fine particles or the binder-to-resin 100 parts by weight (Card) using a thermal transfer sheet (Sample 7 ⁇ : L0) whose amount of organic fine particles is out of the above range, has any of solvent resistance, plasticizer resistance, transparency, and film breakage. It was inferior.
- prints (cards) using a heat transfer sheet (sample 11) using a solvent-soluble resin (polyester) as the binder resin have no resistance to toluene, which is a strong solvent, but have a weak ' ⁇ (xylene ), And all other plasticizer resistance, transparency, and film breakability were good, and it was confirmed that it can be used for applications that require low solvent resistance.
- the present invention at least a part of one surface of the base sheet is provided with a protective layer and an adhesive layer mainly composed of solvent-insoluble organic fine particles, a binder and a resin in this order.
- the protective laminate since the heat-transfer sheet is formed by providing the protected S body in a releasable manner, the protective laminate has good film-cutting properties and is good, and the protective laminate is transferred onto an image, and the protective layer strength ⁇ Since it is located on the surface, the image covered by the protective laminate has good resistance to solvents, plasticizers and the like.
- a printed matter in which an image is formed on a substrate by a thermal sublimation transfer method has an image with excellent durability since at least a part of the image is covered with the protective laminate. .
