好適な熱転写記録方法に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thermal transfer recording method suitable for use in an apparatus for recording an image by a thermal transfer system such as a video printer.

ては分散染料が広く利用されている。2. Description of the Related Art In recent years, for example, in a video printer or the like, a method of recording an image on an image receptor by thermal transfer has been proposed. In such a method, an image is recorded by transferring the dye on the transfer sheet onto the image receptor using a thermal head, but in the usual case, polyester resin is used as the material of the image receiving layer, while the dye is used. For this purpose, disperse dyes are widely used.

いるにすぎず、保持力が非常に小さいため、例えばポリ
塩化ビニルシートなどを密着させておくとこのシートに
染料が移行してしまい、記録像がぼやけてしまうという
問題がある。However, in the case of the conventional thermal transfer method, the dye pigment is merely dispersed in the image-receiving layer and the holding power is very small. If this is done, the dye will migrate to this sheet, and the recorded image will be blurred.

にある。The present invention has been made in view of the above-mentioned problems of the conventional example, and an object of the present invention is to provide a thermal transfer recording method capable of improving the fixing property of a dye in an image receiving layer.

写するものである。According to the present invention, a dye having active hydrogen is used in a transfer sheet and is thermally transferred to a recording sheet on which an image receiving layer containing a compound containing an active olefin is formed.
【０００６】活性水素を有する染料としては、例えば次

【化２】 尚、化１に示す染料と化２に示す化合物とは、いずれも
組合せが可能である。[Chemical 2] The dye shown in Chemical formula 1 and the compound shown in Chemical formula 2 can be combined.

トキシド、臭化エチルマグネシウム等が使用できる。塩
基性触媒の添加量は、５重量％〜１０重量％とすること
が好ましい。５重量％より少ないと反応が促進されず、
また、１０重量％より多いと塩基性触媒が解けなくな
る。尚、染料分子又は受像層分子が塩基性である場合は
塩基性触媒を用いる必要がない。On the other hand, it is also effective that the image receiving layer contains a basic catalyst. As the basic catalyst, for example, sodium ethoxide, potassium ethoxide, lithium ethoxide, ethylmagnesium bromide and the like can be used. The amount of the basic catalyst added is preferably 5% by weight to 10% by weight. If it is less than 5% by weight, the reaction is not promoted,
If it is more than 10% by weight, the basic catalyst cannot be dissolved. When the dye molecule or the image receiving layer molecule is basic, it is not necessary to use a basic catalyst.

が促進される。In the present invention having such a constitution, the active hydrogen in the dye undergoes a nucleophilic addition reaction with the active olefin in the image-receiving layer of the recording sheet to form a covalent bond, whereby the resin of the image-receiving layer and the dye are formed. The dye binds strongly. Then, this prevents migration of the dye from the image receiving layer. In this case, by including a basic catalyst in the image receiving layer, the above reaction is promoted even when the dye molecule or the image receiving layer molecule is not basic.
