摘要：
An image transcription method of transcribing an image of the dye on a printing sheet outputted by e.g., a video printer onto a substrate for transcription, such as a cup of pottery or the like. For transcription, a resin is coated on the surface of the substrate for transcription to form a reception layer. This reception layer is dried in an electrical oven to form a support for transcription. A printing sheet carrying an image of a sublimable dye is stacked on the reception layer of the support for transcription and pressured to the reception layer under application of heat and pressure. As the resin for the reception layer, the acrylic resin or the epoxy resin or both are employed. If the resin composed mainly of the acrylic resin is employed, the viscosity of the resin is set to 43 to 52 seconds in terms of the Ford cup viscosity, and the resin discharge pressure from a spray gun is set to 35 kg/m<2>±0.01 kg.cm<2>. The distance between the spray gun and the substrate for transcription is set to 100 mm±5 mm, while the drying temperature is 170 to 180° C. The thickness of the reception layer is 10 to 50 mum. After transcribing the image of the sublimable dye to the reception layer, a transparent film is bonded, if necessary, as a protective film on the reception layer.
技术功效语段：
It is another object of the present invention to provide a method for transcribing a picture and a support for transcription whereby a picture of a sublimable dye can be transcribed in a short time.
By employing an electrical oven for drying the reception layer, precise temperature control becomes possible, such that the reception layer may be prohibited from being discolored and a transcribed image may be produced. Simultaneously, foreign matter may be prohibited from being mixed during drying by a hot air drying oven to prohibit the lowering in the product quality.
By layering and bonding a transparent film such as a film of acrylic resin as a cover coating on the reception layer, the transparent film operates as a protective layer for significantly improving weatherability and resistance against solvents or chemicals.
If the lubricant is deposited in this manner to the printing sheet, lubricity may be accorded to the printing sheet by the lubricant. In addition, when the printing sheet is layered on the support for transcription, such as a mag-cup, air bubbles intruded into the space between the printing sheet and the support for transcription tend to be discharged to outside so that creases are less liable to be produced. Thus a satisfactory image free of non-transcribed portions can be re-transferred to the support for transcription without the necessity of rubbing the printing sheet surface with a spatula.
权利要求：
What is claimed is:
1. An ink ribbon for image transcription having plural pigment-containing layers with different colors formed on a strip-shaped substrate in a predetermined order,
characterized in that a lubricant is contained in the last-printed pigment containing layer, the lubricant being selected from a group of lubricants consisting of silicon oil, higher fatty acids, metal or amine salts of the higher fatty acids, esters of fatty acids and alcohols, alkyl-phosphoric acid ester and perfluoro polyether.
2. An ink ribbon for image transcription as claimed in claim 1, wherein the higher fatty acids include at least one of myristic acid, palmitic acid, stearic acid and oleic acids.
