うになっている。Such a heat-sensitive transfer material generally has a thermal transfer layer formed on one surface of a substrate, and the thermal transfer layer is selectively heated by a heating head of a thermal transfer recording device to be melted or softened, thereby recording. It is selectively heat-transferred to paper so that recording such as printing is performed. More specifically, using a heating head of a thermal transfer recording apparatus in which a side surface to be opposed to the recording paper is flattened and a heating portion to be formed along a width direction of the heat-sensitive transfer material is protruded at a predetermined position on the flat side surface, The heating section is brought into contact with the thermal transfer material to selectively heat the thermal transfer layer of the thermal transfer material, and the heating causes the thermal transfer layer of a predetermined area to be melted or softened, and this is thermally transferred to recording paper, thereby recording. Recording such as printing on paper is performed.
ところで、前記記録紙としては、一般に表面が平滑と
された熱転写専用の用紙が使用されているが、近年で
は、葉書やボンド紙等の表面の粗い記録紙に印字するこ
とも行われている。By the way, as the recording paper, a paper exclusively for thermal transfer having a smooth surface is generally used. In recent years, printing is also performed on recording paper having a rough surface such as a postcard or a bond paper.

実際に記録紙に転写されるのは、第３図に示すように、
溶融又は軟化された熱転写層のうち、記録紙表面の凹凸
の先端部に接触する一部分のみであり、その結果、記録
紙に転写される単位面積当たりでの熱転写量が非常に少
なくなり、かすれた様な不鮮明な印像しか得られないも
のであった。When printing on such a rough recording paper, the heating part of the heating head is brought into light contact with the thermal transfer material under the same conditions as when printing on thermal transfer paper, and the thermal transfer layer of the thermal transfer material and the recording paper surface Because only the tops of the irregularities are in contact with each other, even when the heat transfer layer of the heat transfer material is heated by the heating unit of the heating head to melt or soften the heat transfer layer having a predetermined area,
What is actually transferred to the recording paper is as shown in FIG.
Of the melted or softened thermal transfer layer, only a part of the surface of the recording paper that comes into contact with the leading end of the irregularities on the surface of the recording paper. Only an unclear image like that described above was obtained.
また、このような印字上の問題点を解消する方法とし

の加熱部と感熱転写材の基材との間での面圧が増大する
ため、この加熱ヘッドの加熱部が感熱転写材の基材に溶
着するステック現象が発生して、印字そのものが不可能
になる問題がある。Further, as a method of solving such a printing problem, it is conceivable to increase the pressing force of the heating portion of the heating head against the thermal transfer material. However, in the case of this method, the contact between the thermal transfer layer of the thermal transfer material and the surface of the recording paper is changed by changing the unevenness of the recording paper surface in contact with the thermal transfer layer of the thermal transfer material with the movement of the heating head. Although the area can be increased, since the surface pressure between the heating portion of the heating head and the base material of the thermal transfer material increases, the heating portion of the heating head is welded to the base material of the thermal transfer material. There is a problem that a stick phenomenon occurs and printing itself becomes impossible.
それ故に、実際問題としては、前記加熱ヘッドの加熱
部による対感熱転写材の押圧力を増加するのにも自ずと
限界があり、上述のような不鮮明な印像は避けられなか
ったのである。Therefore, as a practical problem, there is naturally a limit in increasing the pressing force of the heat-sensitive transfer material by the heating portion of the heating head, and the above-described unclear printing is inevitable.
本発明はかかる事情に鑑みてなされたものであり、表
面が粗い記録紙に対しても鮮明な印像を転写形成するこ
とができる感熱転写材を提供することを目的とする。The present invention has been made in view of such circumstances, and an object of the present invention is to provide a heat-sensitive transfer material capable of forming a clear printed image even on a recording paper having a rough surface.
本発明に係る感熱転写材は、基材の一方の面に熱転写
層を形成してある感熱転写材であつて、前記基材の他方
の面に高弾性を有する微粒子を備えた背面処理層を形成
してある点に特徴を有している。The heat-sensitive transfer material according to the present invention is a heat-sensitive transfer material in which a heat transfer layer is formed on one surface of a base material, and a back treatment layer provided with fine particles having high elasticity on the other surface of the base material. The feature is that it is formed.

押圧されるようになる。When the thermal transfer material having such a configuration is used as a thermal transfer recording medium in a thermal transfer recording apparatus, and printing or the like is performed on recording paper having a rough surface and unevenness, the fine particles are disposed on the back side of the thermal transfer material. Due to the presence, the heating portion of the heating head of the thermal transfer device comes into contact with the fine particles, and the pressing force of the heating portion of the heating head is applied to the base material and the thermal transfer layer via the fine particles. Since the fine particles have high elasticity, they are elastically deformed when a predetermined pressing force is applied, and elastically recover when the pressing force is removed. Therefore, even if the base material and the thermal transfer layer of the thermal transfer material are deformed along the irregularities of the recording paper, the fine particles present at the positions corresponding to the convex portions of the recording paper are directly pressed by the heating section of the heating head. While being greatly elastically deformed, the fine particles present at the position corresponding to the concave portion are formed by the heating unit in such a state as to fill a gap between the heating unit of the heating head and the base material of the thermal transfer material. Becomes pressed.

紙表面に熱転写される結果、従来のように文字等の印像
がかすれたり、とぎれたりすることがなくなり、鮮明な
印像が得られるようになる。Thus, the base material and the thermal transfer layer of the thermal transfer material are pressed by the heating portion of the heating head via the elastically deformable fine particles as described above, so that the thermal transfer material follows the recording paper surface evenly. Therefore, even if the surface of the recording paper is rough and uneven, the thermal transfer layer is uniformly transferred along the surface of the recording paper, and the thermal transfer layer having a predetermined area is thermally transferred to the surface of the recording paper as scheduled. As a result, the image of a character or the like is not faded or cut off as in the related art, and a clear image can be obtained.

Since the fine particles (3) are present on the back side of the heat-sensitive transfer material, the heating unit (6) of the heating head of the thermal transfer device comes into contact with the fine particles (3), and via the fine particles (3), Heating section of the heating head (6)
Is applied to the substrate (1) and the thermal transfer layer (2). Since the fine particles (3) have high elasticity, they are elastically deformed when a predetermined pressing force is applied, and elastically recover when the pressing force is removed. Therefore, the base material (1) of the thermal transfer material is formed along the irregularities of the recording paper (A).
Even if the thermal transfer layer (2) is deformed, the fine particles (3) existing at the positions corresponding to the convex portions of the recording paper (A) are directly pressed by the heating section (6) of the heating head and greatly elastically deform.
