この種のマイクロカプセル、その製造法及び種々の使用可能性はrアンゲバンテ ・ヘミ−J 1975年、第16号、第556〜567頁から公知である。それ によるとマイクロカプセルは芯物質と固体のカプセル壁とからなる、1〜500 0μmの大きさの微粒子であると解される。芯物質はマイクロカプセルの使用目 的に応して、カプセル壁によりカプセル外界から隔離されまたカプセル壁の破壊 又は浸透によってその周囲に意図的に放出することのできる作用物質を含む。カ プセル壁は特に天然又は合成ポリマーからなり、その種類及びカプセル壁の厚さ がマイクロカプセルの外形を球、lj@の房欅集合体又は不規則な構造体として 決定すると共に、一方ではカプセル壁の隔離力及びカプセル内容物の意図的な放 出能を決定する。カプセルは機械的に外部から、すなわち切り込むか又は押し潰 すことによって、又は内部から、すなわちカプセル内容物の沸点以上に加熱する ことにより並びにカプセル壁を溶解、融解又は燃やすことにより開放することが できる。Microcapsules of this type, their production and various possibilities of use are described in R.Angevante. - Known from Hemi-J, 1975, No. 16, pp. 556-567. that According to Microcapsules, microcapsules consist of a core substance and a solid capsule wall. It is understood that they are fine particles with a size of 0 μm. The core substance is used for microcapsules. Depending on the situation, the capsule wall isolates the capsule from the outside world and the destruction of the capsule wall or contain an active substance that can be intentionally released into its surroundings by osmosis. mosquito The capsule wall is composed of a particularly natural or synthetic polymer, its type and the thickness of the capsule wall. The outer shape of the microcapsule is a sphere, a cluster of lj@, or an irregular structure. On the one hand, the isolating forces of the capsule walls and the intended release of the capsule contents Determine performance. The capsule is mechanically removed from the outside, i.e. by cutting or crushing. or from within, i.e. by heating above the boiling point of the capsule contents. and by dissolving, melting or burning the capsule wall. can.
マイクロカプセル化に関しては機械的−物理的方法及び化学的方法が公知である 。化学的方法には界面重縮合法が属し、この方法の場合水と混合不能の溶剤に溶 解した第1モノマーを水−保護コロイド溶液中で激しく撹拌しながら分散させ、 水に溶解した第2モノマーを添加することにより雨上ツマ−を溶剤/水の境界面 で反応させて溶剤含をマイクロカプセルの形の固体ポリマー(重縮合物)を製造 する。Mechanical-physical and chemical methods are known for microencapsulation. . Chemical methods include the interfacial polycondensation method, which uses a solvent that is immiscible with water. Dispersing the dissolved first monomer in a water-protective colloid solution with vigorous stirring, By adding a second monomer dissolved in water, raindrops can be removed at the solvent/water interface. to produce a solid polymer (polycondensate) in the form of a solvent-containing microcapsule. do.
マイクロカプセルの公知の用途としては例えば、片側に発色剤を含むマイクロカ プセル及び顕色剤が被覆されている「セルフ−コンテインド−タイプ」の反応記 録紙が挙げられ、この場合マイクロカプセルが筆記具の圧力により破壊された箇 所に直ちに展開発色剤によって可視マーキングが生しる。Known uses of microcapsules include, for example, microcapsules containing a coloring agent on one side. "Self-contained type" reaction record where the cell and developer are coated In this case, the microcapsules were destroyed by the pressure of the writing instrument. A visible marking is immediately produced by the developing coloring agent.
マイクロカプセルのもう1つの用途は英国特許第2173452号明細書から、 画像記録法との関連において公知である。この場合インキを含むマイクロカプセ ルは記録支持体上に塗布され、記録すべき画像に応してレーザ光線により破壊さ れるか又は少なくともインキ透過性にされ、その結果インキは記録すべき画像に 応して記録紙上に達する。しかしこの方法を実際にどのようにして達成するのか またこれにはいかなるカプセル壁材料が適しているのかは、上記英国特許第21 73452号明細書からは明かでない。Another use of microcapsules is from British Patent No. 2173452: Known in connection with image recording methods. In this case microcapsules containing ink The film is applied onto the recording support and is destroyed by a laser beam depending on the image to be recorded. or at least made ink permeable so that the ink is transparent to the image to be recorded. Accordingly, it reaches the recording paper. But how do you actually accomplish this? Also, what kind of capsule wall material is suitable for this purpose is explained in the above-mentioned British Patent No. 21. It is not clear from the specification of No. 73452.
本発明は、カプセル壁が熱及び/又は光の作用下に破壊される形式の、熱不安定 性及び/又は光子安定性のカプセル壁を存するマイクロカプセルを提供すること を課題とする。The present invention provides thermally unstable Provided are microcapsules having a photon-resistant and/or photon-stable capsule wall. The task is to
本発明によればこの課題は、先に記載した形式のマイクロカプセルにおいて、カ プセル壁のポリマーが熱及び/又は光に不安定な予定破壊点をアゾ官能基(−N −N−)又はジオキシ官能基(−0−0−)の形で含むことによって解決される 。According to the invention, this problem is solved in microcapsules of the type described above. Azo functional group (-N -N-) or dioxy functional group (-0-0-) .
マイクロカプセルの優れた実施態様及び有利な用途は請求の範囲2以下に記載さ れている。Advantageous embodiments and advantageous uses of the microcapsules are set out in claims 2 et seq. It is.
本発明によるマイクロカプセルは、これをカプセル壁内の熱及び/又は光に不安 定な予定破壊点により単に熱又は光で意図的に破壊することによって、カプセル 内容物を放出し得るという特徴を有する。更にこのマイクロカプセルは、これが 機械的に負荷可能でありまたそのカプセル壁がカプセル内容物を浸透しないこと から、簡単かつ確実に取り扱うことができる。他の利点は、アゾ又はジオキシ官 能基の形の予定破壊点が発熱的にまたアゾ官能基の場合には付加的に発射ガス、 すなわち窒素の放出下に分解し、従って熱分解に際してこの分解を起こさせるの に必要な熱エネルギーが放出熱によって軽減されること、またカプセル内容物の 放出がこの発射ガスによって促進されることである。この場合発射ガスの作用は 付加的にカプセル内容物としての低沸点液によって補助される。The microcapsules according to the present invention are sensitive to heat and/or light within the capsule wall. Capsules can be destroyed simply by intentionally destroying them with heat or light through a predetermined, predetermined failure point. It has the characteristic of being able to release its contents. Furthermore, this microcapsule is mechanically loadable and whose capsule walls do not penetrate the capsule contents; It can be handled easily and reliably. Another advantage is that azo or dioxy The intended break point of the functional group is exothermically and, in the case of an azo functional group, additionally a propellant gas, i.e. it decomposes with the release of nitrogen, thus causing this decomposition to occur during thermal decomposition. The thermal energy required for The release is facilitated by this propellant gas. In this case, the action of the propellant gas is It is additionally assisted by a low-boiling liquid as capsule content.
請求の範囲3に記載したカプセル壁ポリマー(FAI)〜(PA6)に対しては 約120〜125°Cの分解温度を得ることができ、従って例えば室温での早期 分解に基づく危険性はない。更にこの分解温度はアゾ及びジオキシ官能基に対し てそれぞれ隣接する基との関連において広範囲に調整することができる。For capsule wall polymers (FAI) to (PA6) described in claim 3, Decomposition temperatures of about 120-125 °C can be obtained, thus e.g. There is no risk due to decomposition. Furthermore, this decomposition temperature is can be adjusted within a wide range in relation to the respective adjacent groups.
カプセル壁の機械的特性は主としてポリマーの種類によって影響され、この場合 ポリマーとは重縮合物又は重付加生成物を意味する。すなわち例えばカプセル内 容物をカプセル外界から保護するマイクロカプセルの能力は、架橋ポリマーにあ っては線状ポリマーの場合よりも高い。カプセル壁の破壊に対して決定的なファ クタはカプセル壁内の予定破壊点の種類及び数であり、この場合予定破壊点の数 は出発上ツマ−を付加的な熱及び光安定性の出発モノマーと共重合させることに よって有利に調整することができる。The mechanical properties of the capsule wall are mainly influenced by the type of polymer, in this case By polymer is meant a polycondensate or a polyaddition product. i.e. inside a capsule The ability of microcapsules to protect their contents from the outside world is due to the cross-linked polymer. is higher than that for linear polymers. A decisive factor against capsule wall failure. Kuta is the type and number of planned failure points in the capsule wall, in this case the number of planned failure points. The starting material is copolymerized with additional heat- and light-stable starting monomers. Therefore, it can be adjusted advantageously.
本発明によるマイクロカプセルは例えば薬荊、食品、農薬、現像剤、硬化剤、耐 燃剤その他多くの作用物質を所望時点で熱及び/又は光を作用させることによっ て放出させるのに特に適している。1つの優れた用途は熱又はレーザ転写印刷で のマイクロカプセルである。この場合染料又は発色剤を含むマイクロカプセルは 直接記録支持体上にか又は印字すべき記録支持体に接触するインキリボンに塗布 され、熱印字ヘッドによる熱によってか又はレーザによるエネルギーに富んだ光 線によってカプセル内容物の放出下に破壊される。この場合印字すべき記録支持 体への着色は発熱的に解放される熱及び発射ガスによって補助される。The microcapsules according to the present invention can be used, for example, in medicines, foods, agricultural chemicals, developers, hardeners, resistant Combustion agents and many other agents can be prepared at desired times by the action of heat and/or light. Particularly suitable for release. One excellent application is thermal or laser transfer printing. microcapsules. In this case, the microcapsules containing the dye or color former are Application directly onto the recording support or onto an ink ribbon in contact with the recording support to be printed by heat from a thermal print head or by energetic light from a laser. The capsule is destroyed by the rays releasing its contents. Record support to be printed in this case Coloring of the body is assisted by exothermically released heat and propellant gas.
