た。As described above, conventionally, an image receiving layer transfer in which a release layer is provided between the base material and the image receiving layer so that the transfer energy at the time of transferring the image receiving layer becomes small. A body is used, and as the release layer, a release layer made of a silicone-based material is often used because of its excellent surface releasability. However, the thickness is 10
In order to form a thin image receiving layer having a thickness of μ or less, the viscosity of the coating material for forming the image receiving layer is set to a low viscosity of 200 centipoise (cP) or less, and the image receiving layer is formed on the release layer made of this silicone material. When a coating film is formed, cissing of the coating material occurs on the release layer, defects such as pinhoe occur in the coating film, and the problem that the image receiving layer cannot be formed uniformly occurs. Further, the dye that has permeated the image-receiving layer by image recording may reach the base of the image-receiving layer (for example, the image-receiving body, an intermediate medium, etc.) and contaminate the base. Therefore, as the image-receiving layer transfer member, the image-receiving layer and the release layer are separated. Similar problems occurred when a barrier layer was provided between the two or when the image receiving layer was covered with the barrier layer.

ともできる。The coating material for forming the image-receiving layer or the barrier layer used in the present invention is not particularly limited, but when it is directly coated on the silicone release layer or at least a part of the coating material. When it is directly coated on the silicone-based release layer, a resin obtained by dissolving at least the resin forming the image receiving layer or the barrier layer in a solvent containing alcohol is used. Examples of the resin forming the image receiving layer or the barrier layer include acrylic resin, styrene resin, urethane resin, polyester resin, polyvinyl acetal resin, vinyl acetate resin, amide resin,
At least one selected from cellulose resins, olefin resins, chlorinated resins and the like can be used.
More specifically, acrylonitrile-styrene copolymer resin, polystyrene, styrene-acrylic copolymer resin, saturated polyester, polyester urethane, chlorinated rubber, chlorinated polypropylene, vinyl chloride resin, chlorinated vinyl chloride resin, vinyl chloride-vinyl acetate. Copolymer resins (including those in which vinyl alcohol, maleic acid, and other components are further copolymerized), vinyl chloride-acrylic acid ester copolymer resins (multi-component copolymers using multiple acrylic acid esters) It is preferable to use at least one selected from the group consisting of polymerized resin), vinyl acetate resin, polycarbonate, and cellulose resin. The polyvinyl acetal resin is preferably a resin obtained by reacting polyvinyl alcohol with an aldehyde, and the aldehyde includes aliphatic aldehydes such as formaldehyde, acetaldehyde, propionaldehyde, butyraldehyde, and benzaldehyde. At least one selected from aromatic aldehydes such as Examples of the solvent that dissolves the resin forming the image receiving layer or the barrier layer include ketone solvents such as 2-butanone (methyl ethyl ketone), 4-methyl-2-pentanone (methyl isobutyl ketone), cyclohexanone, toluene, xylene, etc. Various solvents such as aromatic solvents, ester solvents such as ethyl acetate and butyl acetate, chlorine solvents such as methylene chloride and monochlorobenzene, and ether solvents such as tetrahydrofuran can be used and are selected from them. At least one type is used. 2 of these
-Butanone has a proper polarity as compared with an aromatic solvent such as toluene or an alcohol solvent, and is a good solvent (good solvent) for many resins. A paint having a viscosity can be easily produced. Therefore, 2-butanone is preferable for forming a thin coating film. Further, as the alcohol, one or more hydrogen atoms of a chain or cyclic saturated or unsaturated aliphatic hydrocarbon are replaced with a hydroxyl group (—OH).
Various alcohols obtained by substituting with can be used. Specifically, methyl alcohol, ethyl alcohol
, Isopropyl alcohol, butyl alcohol, t-
Lower alcohols such as butyl alcohol can be mentioned, and it is preferable to use at least one selected from these. Particularly, when isopropyl alcohol is used among these, a more excellent crater prevention effect is obtained,
For example, when a coating film is formed using a gravure printing method, even if a plate having a large number of lines of 100 or more is used, a coating film for an image receiving layer is formed on a coating film for a release layer. Alternatively, the coating film for the barrier layer can be formed to have a uniform thickness without causing cissing. In the present invention, alcohol may be used alone as a solvent for dissolving the resin forming the image receiving layer or the barrier layer without being mixed with the above solvent.
Further, it does not matter whether the alcohol is a good soluble solvent (good solvent) or a poorly soluble solvent (poor solvent) with respect to the resin forming the image receiving layer or the barrier layer. In the present invention, in addition to the alcohol, a silicone compound or a fluorine compound may be added to the coating material for forming the image receiving layer or the barrier layer. Examples of the silicone compound include, for example, the silicone compound and silicone used in the above-mentioned silicone release layer.
A surfactant can be used. As the fluorine compound, for example, a fluorine-based surfactant can be used. Specific examples of the fluorine-based surfactant include MEGAFAC (trade name), F-144D, F-172, F-173, and F-1 manufactured by Dainippon Ink and Chemicals, Inc.

In particular, when a fluorine-based surfactant is present in the coating material together with the alcohol, the cissing prevention effect on the silicone release layer (or the coating film made of the coating material for forming the silicone release layer) is more improved. It will be excellent. In addition, a phenol compound such as bisphenol A which is a developer of a leuco dye, a carboxylic acid compound, an electron accepting substance such as silica or activated clay is added to the coating material for forming the image receiving layer.
