用いた昇華型感熱転写方式は優れた中間調の記録を得る

高分子を主体とする層を染着層として設けたもの、或は
放射線硬化型のオリゴマー，モノマーを硬化させて得ら
れる層を染着層として設けたもの等が提案されている。As the image receiving paper used for this recording, a layer mainly composed of a polymer having high affinity for a sublimation dye, for example, a polymer such as polyester, polyvinyl chloride, or polyvinyl butyral, is dyed on a substrate. There has been proposed one provided as a dyeing layer, or one provided with a layer obtained by curing a radiation-curable oligomer or monomer as a dyeing layer.

起るからである。特に湿熱に対しては弱く、高温，高湿
下においては上記現象が著しく進行する。However, the above-described sublimation type thermal transfer recording method has a drawback that the obtained recorded image has poor storage stability. This is because sublimation and dyed dyes re-sublimate during storage,
This is because they are oxidized by oxygen in the air, causing discoloration, discoloration, bleeding, and the like. In particular, it is weak against wet heat, and the above-mentioned phenomenon remarkably progresses under high temperature and high humidity.
このため、従来の方法では、保存性を高めようとする
と染着濃度が低下したり、染着濃度を高めようとすると
保存性が悪くなるばかりでなく、染着層とカラーシート
との間に融着が起って画像に地汚れ等が発生する等の問
題があった。For this reason, in the conventional method, the dyeing concentration is lowered when trying to increase the preservability, and not only does the preservability deteriorate when trying to increase the dyeing concentration, but also between the dyeing layer and the color sheet. There has been a problem that fusing occurs and the image becomes soiled.

の他、本発明受像紙を用いてプリントを行なう際の態様
等について説明すれば、次の通りである。As described above, the thermal transfer image-receiving paper of the present invention comprises a dyeing layer laminated on the surface of a base material containing fine powdered silica having high hydrophobicity and a high specific surface area. The materials used, the type of the finely powdered silica to be contained in the dyed layer, and other aspects of printing using the image receiving paper of the present invention, and the like will be described below.
前記受像紙の基材には適宜の平坦な素材、例えば、
ポリプロピレン，ポリエステル等の平坦なフィルム、予

材等が用いられる。A suitable flat material for the base material of the image receiving paper, for example,
A flat film such as polypropylene or polyester, a film having whiteness and opacity in advance, or a porous material such as synthetic paper is used, and a material having good cushioning and flatness is used.
染着層としては、昇華型染料の染着され易い樹脂、
例えば、ポリエステル，ポリ塩化ビニル，ポリビニルブ
チラール等を溶剤に溶解してこれに高疎水性，高比表面
積を有する微粉末シリカを混入し、塗布後硬化させて染
着層としたものが用いられる。As the dyeing layer, a resin that is easy to dye a sublimation dye,
For example, a dyeing layer obtained by dissolving polyester, polyvinyl chloride, polyvinyl butyral, or the like in a solvent, mixing finely powdered silica having high hydrophobicity and high specific surface area, and curing after application is used.
また、同様に昇華型染料の染着され易いオリゴマー，
モノマーに上述の微粉末シリカを混入し、塗布後、放射
線硬化させて染着層となしたもの等も用いられる。Similarly, oligomers that are easily dyed with a sublimation dye,
The above-mentioned fine powdered silica is mixed with a monomer, and after coating, radiation cured to form a dyeing layer.
一方、昇華型染料に加える疎水性微粉末シリカとし
ては、例えば、シラノール基をメチル基等アルキル基に
置換されたもの等であるが、特に限定されるものではな
い。しかし、その疎水率はM.W値（注１）で60以上であ
る。On the other hand, examples of the hydrophobic fine powder silica to be added to the sublimation dye include, for example, those in which a silanol group is substituted with an alkyl group such as a methyl group, but is not particularly limited. However, its hydrophobicity is 60 or more in MW (Note 1).
注１ M.W値（デグサ社試験法） 水50mlに試料シリカ0.5gを加え、これにメタノールを
滴下させ、シリカの濡れを観察する。試料シリカが完全
に濡れた状態を示すところを終点とし、下記の式でM.W
値を求める。Note 1 MW value (Degussa test method) 0.5 g of sample silica is added to 50 ml of water, and methanol is dropped to this, and the wettability of the silica is observed. The point where the sample silica shows a completely wet state is defined as the end point, and the following equation
Find the value.
x:メタノール消費ml数 疎水率の低い、例えば、40〜35の値をもつシリカを用
いると、画質の保存性が劣り、退色，にじみ等が発生
し、疎水性が高いほど退色，にじみ等が発生しなくな
り、混入量も小量ですむ。 x: Number of ml of methanol consumed When using silica having a low hydrophobicity, for example, a value of 40 to 35, the preservation of image quality is inferior, fading and bleeding occur, and the higher the hydrophobicity, the more fading and bleeding occur. It does not occur and the amount of contamination is small.
また、微粉末シリカの粒径は10〜20mμであるが、比
表面積即ち単位重量当りの表面積で表わすと、100（m2/
g）以上のものがよく、好ましくは150（m2/g）以上がよ
い。粒径の粗い、例えば、80（m2/g）以下のものを用い
ると、混入量を増す必要があり、結果的に昇華した染料
の染着濃度が低くなる。Although the particle size of the finely divided silica is 10～20Emumyu, expressed by the surface area of the specific surface area i.e. per unit weight, 100 (m 2 /
g) or more, and preferably 150 (m 2 / g) or more. If a particle having a coarse particle size, for example, 80 (m 2 / g) or less is used, it is necessary to increase the mixing amount, and as a result, the dyeing concentration of the sublimed dye decreases.
以上のため、高疎水率，高比表面積を持つ微粉末を用
いると、画質保存性が最もよく、高温，高湿に充分耐ら
れる記録画像を得ることができる。As described above, when a fine powder having a high hydrophobicity and a high specific surface area is used, it is possible to obtain a recorded image having the best image preservability and sufficiently withstanding high temperature and high humidity.
而して、上述の微粉末シリカを用いる量は、樹脂10
0量部に対して１部以上、30部以上であるが、好ましく
は３部以上15部以下が好ましい。Thus, the amount of the above-mentioned fine powder silica used is the resin 10
The amount is 1 part or more and 30 parts or more, preferably 3 parts or more and 15 parts or less based on 0 parts by weight.
その他、染着層の塗工方法としては通常の方法を用
いることができ、塗布方法は特に限定されることはな
い。In addition, a usual method can be used as a coating method of the dyeing layer, and the coating method is not particularly limited.
塗膜の厚みは３μ以上が好ましく、薄くなり過ぎると
転移濃度は低くなり、保存性も劣ってくる。The thickness of the coating film is preferably 3 μm or more, and if it is too thin, the transfer density becomes low and the storage stability is poor.
一方、水性樹脂と水性微粉末シリカを混入して形成
した染着層は、プリント時の発色は鮮明であったが、保
存中に退色，にじみ等が発生した。On the other hand, the dyeing layer formed by mixing the aqueous resin and the aqueous fine powder silica had a clear color at the time of printing, but suffered fading, bleeding and the like during storage.

た。This aqueous finely powdered silica is a fine particle, for example,
Even if a material having a specific surface area of 200 (m 2 / g) was used and the amount of contamination was increased, the phenomenon of fading and bleeding was inevitable.
本発明の感熱転写受像紙を用いてプリントするに際
しては、従来品と同様に染着層の上に離型層を設けた

ラシートと受像紙との間にポリエチレンフィルム等昇華
性染料の通過し易いフィルムを介在させてプリントして
もよい。When printing using the heat-sensitive transfer image-receiving paper of the present invention, a release layer is provided on a dyeing layer in the same manner as a conventional product, or a release sheet is provided on a blank sheet. And a film through which a sublimable dye such as a polyethylene film can easily pass.
要するに、カラーシートと該受像紙が融着を起こすこ
となく鮮明なる画像を得る方法であれば、いづれでもよ

本発明は上述の通りであって、高比表面積を有し、M.
Wが60以上という高疎水率の微粉末シリカを染着層に含
有させることにより、保存性が著しく向上した。The present invention is as described above, has a high specific surface area, M.
By containing finely divided silica having a high hydrophobicity of W of 60 or more in the dyed layer, the storage stability was remarkably improved.
特に高温，高湿下における画質保存性の効果は顕著な
ものがあり、昇華型の記録画像の保存性の問題は、本発
明によって一挙に解決することができるのであるが、そ
の作用については次のように推定される。In particular, the effect of preservation of image quality under high temperature and high humidity is remarkable, and the problem of preservation of sublimation type recorded images can be solved at once by the present invention. It is estimated as follows.
染着層に昇華，拡散され染着された染料分子は染着層
の分子間に染着されているが、時間と共に再昇華し、あ
る染料分子は染着層の内部で水平移動し、画質としては
にじみとなって表われる。また、染着層の内部で上下移
動した染料分子は染着層外へ去るか、若しくは基材方向
へ移動して退色の原因となり、空気中の酸素又は染着層
内部の酸素に酸化された染料分子は変質し、退色，変色
となって画質に表われる。The dye molecules sublimed and diffused in the dyeing layer are dyed between the molecules of the dyeing layer, but re-sublimate over time, and some dye molecules move horizontally inside the dyeing layer, and the image quality is improved. It appears as a bleed. In addition, the dye molecules that have moved up and down inside the dyeing layer leave the dyeing layer or move in the direction of the substrate to cause discoloration, and were oxidized to oxygen in the air or oxygen inside the dyeing layer. The dye molecules are deteriorated, discolored and discolored, and appear in the image quality.
これ等の染料分子の移動は、染着層に与えられた熱エ
ネルギーによって活発化するが、このとき、空気中の水
分子、又は染着層に介在する水分子によって互に助長さ
れる。一方、これらの水分子は染料分子の移動を促すば
かりか、染料分子が酸化される作用にも影響を及ぼし、
酸化反応を促進させるものと推定される。従って、高
温，高湿下における染着層にあっては染料分子の移動，
酸化が更に活発になり、退色，変色，にじみ等が常温，
常湿下におけるよりも更に促進されるのである。The movement of these dye molecules is activated by the heat energy given to the dyeing layer, and at this time, they are mutually promoted by water molecules in the air or water molecules interposed in the dyeing layer. On the other hand, these water molecules not only promote the movement of the dye molecules, but also influence the oxidation of the dye molecules,
It is presumed to promote the oxidation reaction. Therefore, in the dyeing layer under high temperature and high humidity,
Oxidation becomes more active, fading, discoloration, bleeding, etc.
It is further promoted than under normal humidity.
また、疎水性シリカを得る方法は、一般に下式のよう
に、シラノール基を有機ケイ素ハロゲン化物やアルコー
ル類と反応させることによって置換し、シラノール基を
減少させることによって得られる。Further, a method for obtaining hydrophobic silica is generally obtained by substituting a silanol group by reacting it with an organosilicon halide or an alcohol to reduce the silanol group as shown in the following formula.
以上のような疎水性微粉末シリカはこれを染着層に介
在することにより、染料分子の移動を防ぐと共に、染着
層を疎水化させる作用をなす。 By interposing this in the dyeing layer, the above-mentioned hydrophobic fine powder silica prevents the movement of the dye molecules and acts to make the dyeing layer hydrophobic.
従って、疎水率の大きいもの程、染着層の染料分子の
移動を防ぐ働きが大きくなる。Therefore, the greater the hydrophobicity, the greater the function of preventing the movement of the dye molecules in the dyeing layer.
疎水率の低い微粉末シリカにあっては、メチル基が少
ない分、シラノール基を多く持つこととなって、逆に吸
湿する作用をなし、染着層における染料分子の移動，酸
化反応をかえって活発化することとなる。実際に、疎水
率の低い微粉末シリカを用いたものは、疎水率の高い微
粉末シリカを用いたものに比してはるかに保存性が劣
り、また、他の吸水性を有する無機物、例えば、親水性
シリカ，酸化チタン等のフィラー等を染着層に混入した
場合も著しく保存性の劣ることが判明した。Fine powdered silica with low hydrophobicity has more silanol groups because of less methyl groups, conversely acts to absorb moisture, and is active rather than transferring dye molecules in the dyeing layer and oxidizing reaction. It will become. In fact, those using finely divided silica having low hydrophobicity are much less preservable than those using finely divided silica having high hydrophobicity, and also have other water-absorbing inorganic substances, for example, It has been found that when fillers such as hydrophilic silica and titanium oxide are mixed in the dyeing layer, the storage stability is remarkably poor.
一方、高疎水率の微粉末シリカにあっては、比表面積
の大きいものほど小量の添加で効果が大きかった。従っ
て、高疎水率，高比表面積の微粉末シリカを用いれば、
混入量が少くてすむと共に、低エネルギーで昇華，染着
できることとなり、一定のエネルギーのプリントにおい
ては高濃度で鮮明な画像を得ることができた。On the other hand, in the case of finely powdered silica having a high hydrophobicity, the larger the specific surface area, the greater the effect by adding a small amount. Therefore, if fine powder silica having high hydrophobicity and high specific surface area is used,
In addition to a small amount of contamination, sublimation and dyeing can be performed with low energy, and a clear image with high density could be obtained in printing with a constant energy.
以上のように、染着層に高疎水率，高比表面積を有す
る微粉末シリカを用いることによって、鮮明で且つ保存
性の優れた記録画像を得ることができるのである。As described above, by using fine powdered silica having a high hydrophobicity and a high specific surface area for the dyeing layer, it is possible to obtain a clear recorded image having excellent storage stability.
