Abstract

PURPOSE:To prevent heat fusion and deformation by a thermal head, and to improve transfer properties and shelf stability by forming an image receiving layer containing a chlorinated polyester resin cured substance onto one surface of a base material. CONSTITUTION:A substance including a chlorinated polyester resin cured substance is used as an image receiving layer shaped to a base material, and it may be formed onto one surface of the base material or they may be shaped onto both surfaces. Since chlorinated polyester resin cured substance itself displays high dyeing properties to a sublimating dyestuff, image receiving paper having excellent dyeing properties and shelf stability is acquired even when a composition is coating-cured directly to the base material. A substance easily available on the market can be used as the chlorinated polyester resin, and a photopolymerization initiator represented by 1-hydroxycyclophenylketone, etc., is added and the resin is cured through ultraviolet irradiation, electron beam irradiation or heating methods, etc. Image receiving paper, which has high gloss and high transfer density and in a curl and a printed section of which gloss is not lowered, is obtained.

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an image receiving paper used in raised-type thermal transfer recording. (Prior Art) The image-receiving layer of sublimation-type thermal transfer image-receiving paper has conventionally used a mature plastic resin, such as saturated copolymerized polyester, which has strong dyeability against sublimation dyes. However, this type of resin generally has low heat resistance, so 1) the heat applied during transfer causes fusion with the ink sheet; 2) even if the receiving paper is finished with high gloss, the thermal head The problem is that the surface becomes uneven and the printed area loses its luster. Problem l) can be prevented by adding a silicone-based or fluorine-based surfactant as an additive, but in order to improve problem 2), the heat resistance of the image-receiving layer must be increased. There must be. So, for example. A method of forming an image-receiving layer by crosslinking a thermoplastic resin with a curable monomer or oligomer (Japanese Unexamined Patent Application Publication No. 1983-1999)
2 1 2994) and a method of forming an image-receiving layer by providing a curable resin layer on a thermoplastic resin layer (Japanese Patent Laid-Open No. 61-127)
392), it has been suggested that heat resistance can be imparted. The curable resins used in these methods include diallyl phthalate, trimethylbropanolpropane tri(meth)acrylate, trimethylolethane (meth)acrylate, tetramethylolmethane tri(meth)acrylate, and 1.6- hexane diol di(
Polyfunctional monomers such as methacrylate, polyester acrylate, epoxy acrylate,
There are products made by polymerizing and curing oligomers such as polyurethane acrylate, polyether acrylate, melamine acrylate, alkyd acrylate, and silicone acrylate. (Problems to be Solved by the Invention) However, the curable resin used in the conventional method aimed at improving heat resistance has the property of having low dyeability with sublimation dyes. Because of this,
Even if heat resistance improves, the transfer density may decrease. Therefore, the content of the curable resin in the image-receiving layer must be kept within a range that provides sufficient transfer density, but if this is done, the surface hardness will not be sufficient and the thermal head will The disadvantage is that the printed area becomes uneven and loses its luster. The present invention solves the problems of the prior art as described above, and provides a sublimation type thermal transfer image-receiving paper that does not undergo deformation due to heat fusion or a thermal head, and has good transferability and storage stability. It was done for the purpose of (Means for Solving the Problems) In order to achieve the above object, the present invention employs an image-receiving structure that includes a cured chlorinated polyester resin having high dyeability to sublimable dyes on at least one side of the base material. It is characterized by having layers. The present invention will be explained in detail below. First, examples of the base material used in the present invention include plastic sheets, paper, and synthetic paper. As mentioned above, the image-receiving layer provided on the base material contains a cured chlorinated polyester resin, and this image-receiving layer may be provided on one side or both sides of the base material. It is something. Additionally, this image-receiving layer may be provided after subjecting the base material to an appropriate surface treatment, but since the cured chlorinated polyester resin itself exhibits high dyeability to sublimation dyes, chlorinated polyester resin etc. Even if the composition containing the dye is directly applied to a substrate and cured, it is possible to obtain an image-receiving paper with good dyeability and good storage stability. In order to improve mold releasability, it is preferable to add a silicone-based or fluorine-based surfactant or to copolymerize silicone acrylate. The above-mentioned chlorinated polyester resin is EBECR manufactured by Daicel UCB, which is easily available as a commercial product.
YL 584 and the same < EBECRYL 585 can be exemplified, and its curing can be performed with 1-hydroxycyclophenyl ketone, benzyl dimethyl ketal, 2-hydroxy-2-methyl-1-phenyl-propane-1-
This can be carried out by adding a photopolymerization initiator such as On, etc., and irradiating it with ultraviolet rays, electron beams, or heating. In addition, methods for deepening the color include 1) adding a color deepening agent such as polyoxyalkylene, or 2) dissolving a thermoplastic resin that has strong dyeing properties for sublimation dyes in an organic solvent and chlorinating it. There are known methods such as mixing with a polyester resin and curing it, and 3) using a base material that has cushioning properties with excellent adhesion to the thermal head, but these methods are applied to the image-receiving paper of the present invention. You can also do that. (Operations and Effects of the Invention) According to the present invention described above, since a cured chlorinated polyester resin is used for the image-receiving layer, high gloss and high transfer density are achieved, and no curling or reduction in gloss occurs in printed areas. You can obtain receiving paper. Furthermore, since the cured product itself has high dyeability, by selecting the base material, a high dyeing density can be obtained without mixing a thermoplastic resin. Furthermore, if a thermoplastic resin is not mixed, organic solvents are no longer necessary, which greatly expands the range of base material selections and enables direct coating on ordinary paper, which was previously considered difficult. The present invention is extremely excellent as a rising violet type thermal transfer image receiving paper. (Example) Next, an example of the present invention will be described. Example 1 0.1 of coating liquid 1 having the following composition was applied to the back side of commercially available synthetic paper (Nisshinbo Beach Coat SEX105 single-sided coating).
