- a decorative film containing precious metal components is sometimes formed on the surface of ceramic products such as ceramics, glassware, and enamelware in order to give an elegant or luxurious impression.
- This type of decorative film is formed by applying a decorative composition containing predetermined components to the surface of a ceramic product and then performing a firing treatment.
- a decorative composition is a metal resinate (an organic compound of metal) containing a noble metal element and a glass matrix element. Upon firing such a decorative composition, a decorative film is formed that includes glass regions and precious metal regions.

- the inventor of the present invention considered incorporating a rare earth element into the glass region of the decorative film after firing treatment.
- the presence of a rare earth element in the glass matrix can improve the alkali resistance of the glass (see Non-Patent Document 1). It is believed that such an effect of improving the alkali resistance is caused by doping the glass matrix with a rare earth element having a high affinity for oxygen, thereby tightening the network structure of the glass and suppressing the penetration of alkali ions.
- rare earth oxides remain and form a film even after other components are eluted by exposure to an alkaline chemical, it is believed that they also have the effect of suppressing alkali corrosion.
- the decoration film containing the rare earth element in the glass region has improved alkali resistance, but has low acid resistance. be.

- the decorative composition having the above structure contains a certain amount of rare earth elements, it is possible to form a decorative film having a glass region containing rare earth elements. Since the decorative film containing such a rare earth element has excellent alkali resistance, it is possible to suppress breakage during washing with an alkaline detergent.
- the content of the first element (Si, Al) is adjusted to 50 mol % or more. As a result, the acid resistance of the decorative film after the baking treatment can be sufficiently improved, so that damage caused by washing with an acid detergent can be suppressed.

- the chemical resistance of the glass region itself is improved, so even if the amount of exposure of the glass region increases, damage to the decorative film can be suitably suppressed. That is, the technique disclosed herein can be applied particularly preferably to a microwaveable decorative composition.
- the content of the first element is 55 mol % or more and 86 mol % or less when the total number of moles of the glass matrix elements is 100 mol %. This makes it possible to form a decorative film having both high levels of alkali resistance and acid resistance.
- the Al content is 0 mol % or more and 80 mol % or less when the total number of moles of the first element is 100 mol %.
- Al When Al is added, it interacts with the rare earth element to make the glass structure more rigid, so that the alkali resistance is further increased.
- Si plays a role in forming a skeleton of the glass, and when the amount of Si added becomes relatively small due to the addition of Al, the glass skeleton itself becomes weaker, resulting in lower chemical resistance. From this point of view, it is preferable to set the maximum content of Al in the first element to 80 mol % or less to secure a certain amount or more of Si.
- the glass matrix element further contains at least one second element selected from the group consisting of Zr, Ti and Co.

Abstract
Description
以下、ここに開示される装飾用組成物について説明する。かかる装飾用組成物は、少なくとも、貴金属元素と、ガラスマトリクス元素とを含有する。以下、各々について具体的に説明する。
貴金属元素は、装飾用組成物の焼成体(すなわち、装飾膜)の着色に寄与する成分である。具体的には、ここで開示される装飾用組成物は、貴金属元素として、金(Au)、銀(Ag)、白金(Pt)、ロジウム(Rh)、イリジウム(Ir)、パラジウム(Pd)、ルテニウム(Ru)、およびオスミウム(Os)を含み得る。なお、優美又は豪華な印象を与える装飾膜を比較的容易に形成できるという観点から、これらの貴金属元素のなかでも、Au、Ag、Pt、Rh、Ir、Pdが好適である。なお、貴金属元素は、例えば、金属レジネート(金属の有機化合物)の状態で装飾用組成物中に含まれ得る。なお、装飾用組成物中の貴金属元素の状態は、上述の金属レジネートに限定されず、錯体や重合体であってもよいし、金属粒子であってもよい。
本明細書において「ガラスマトリクス元素」とは、焼成処理後の装飾膜のガラス領域においてマトリクス構造を構築し得る金属元素と半金属元素を包含する概念である。かかるガラスマトリクス元素の一例として、Al、Ti、Zr、Si、Bi、Sm、Y、La、Ce、Pr、Nd、Sm、Dy、Sn、Zn、Be、Mg、Ca、Sr、Ba、Li、Na、K、Rb、B、V、Fe、Cu、P、Sc、Pm、Eu、Gd、Tb、Ho、Er、Tm、Yb、Lu、Ni、In、Co、Cr等が挙げられる。なお、上述した貴金属元素の中には、焼成処理において一部が酸化してガラスマトリクスに混入し得る元素(Agなど)も存在する。しかし、本明細書では、便宜上、上記(1)貴金属元素にて挙げた元素はガラスマトリクス元素とみなさないものとする。すなわち、本明細書における「ガラスマトリクス元素の総モル数」とは、ガラス領域のマトリクスを形成し得る金属元素と半金属元素のうち、貴金属元素を除いた元素の総モル数を示す。なお、貴金属元素と同様に、装飾用組成物中のガラスマトリクス元素の形態は、特に限定されず、金属レジネート、錯体、重合体、微細な粒子(ガラスフリット)などの形態をとり得る。
希土類元素は、スカンジウム(Sc)、イットリウム(Y)、ランタン(La)、セリウム(Ce)、プラセオジム(Pr)、ネオジム(Nd)、プロメチウム(Pm)、サマリウム(Sm)、ユウロピウム(Eu)、ガドリニウム(Gd)、テルビウム(Tb)、ジスプロシウム(Dy)、ホルミウム(Ho)、エルビウム(Er)、ツリウム(Tm)、イッテルビウム(Yb)、ルテチウム(Lu)のなかから特に制限なく選択できる。これらの希土類元素は、酸素親和性が高いため、ガラスマトリクス中にドープされることでガラスの網目構造を引き締めることができる。また、希土類酸化物は、アルカリ性薬剤の曝露によって他の成分が溶出した後も残留して被膜化する。これによって、ガラス領域の内部にアルカリが侵入して装飾膜を破損させることを抑制できる。なお、上述の希土類元素のなかでも、Y、La、Ce、Pr、Nd、Sm、Dyは、ガラス領域の耐アルカリ性をより適切に向上できるため好適である。
上述した通り、ここに開示される装飾用組成物は、ガラスマトリクス元素の第1元素としてケイ素(Si)および(又は)アルミニウム(Al)を含有する。まず、Siは、焼成処理後に酸化ケイ素(SiO2)となり、ガラスマトリクスの骨格を構成する。次に、Alは、その一部が他の元素(Si、希土類元素、第二元素等)との複合酸化物を形成し、ガラスマトリクスの耐化学性を強化すると推測される。そして、本発明者が行った実験によると、ガラス領域に希土類元素を含む装飾膜において実用上十分な耐酸性を確保するためには、ケイ素(Si)とアルミニウム(Al)の合計含有量が一定の値を超える必要があることが確認されている。
また、ここに開示される装飾用組成物は、ジルコニウム(Zr)、チタン(Ti)およびコバルト(Co)から選択される少なくとも一つを第2元素として含有していると好ましい。これらの第2元素の酸化物は、焼成後の装飾膜の耐化学性をさらに向上させることが確認されている。ここに開示される技術を限定する意図はないが、かかる効果が得られる理由は、以下のように推測される。まず、Zrは焼成処理後に酸化ジルコニウム(ZrO2)となり、Tiは焼成処理後に酸化チタン(TiO2)となる。これらのZrO2やTiO2は、ガラス網目修飾イオンとしてケイ酸ガラス骨格と複合化していると推測される。そして、ZrO2やTiO2は、単独材料として耐化学性が非常に高いため、アルカリ性薬剤の曝露によって他成分が溶出した後も残留して被膜を形成し、焼成後の装飾膜の耐化学性の向上に貢献していると予想される。一方、Coは焼成処理後に酸化コバルト(CoO、Co3O4、Co2O3の少なくとも何れか)となる。この酸化コバルトもガラス網目修飾イオンとしてガラス骨格と複合化していると推測される。そして、酸化コバルトは、貴金属とガラスマトリクスの密着性を強化することで、焼成後の装飾膜の耐化学性の向上に貢献していると予想される。
また、ここに開示される装飾用組成物のガラスマトリクス元素は、ビスマス(Bi)を含有していることが好ましい。Biは、焼成処理後に酸化ビスマス(Bi2O3)となり、ガラスマトリクスの骨格の一部を構成する。かかるBi2O3は、ガラスを軟化させる効果があるため接着性が向上し、また、基材がガラスである場合には基材へ拡散することでより高い接着効果が得られる。これらの接着性の向上によって、アルカリ性薬剤に曝露された際の装飾膜の剥離を抑制できる。かかるBiの添加による効果をより好適に発揮させるという観点から、ガラスマトリクス元素中のBiの含有量は、1mol%以上が好ましく、3mol%以上がより好ましく、5mol%以上がさらに好ましく、6mol%以上が特に好ましい。一方、Biの含有量を増加させすぎると、希土類元素や第1元素の含有量が相対的に低下するため、装飾膜の耐化学性が却って低下するおそれがある。かかる観点から、ガラスマトリクス元素中のBiの含有量の上限は、15mol%以下が好ましく、14mol%以下がより好ましく、13mol%以下がさらに好ましく、12mol%以下が特に好ましい。
ここで開示される装飾用組成物は、ここに開示される技術の効果を損なわない範囲において、上述した元素以外の金属元素若しくは半金属元素をガラスマトリクス元素として含有し得る。このような他の元素としては、Sn、Zn、Be、Mg、Ca、Sr、Ba、Li、Na、K、Rb、B、V、Fe、Cu、P、Ni、Crなどが挙げられる。なお、装飾膜の耐化学性という観点では、ガラスマトリクス元素中の他の元素の含有量の下限値は、特に限定されず、0.1mol%以上であってもよく、0.5mol%以上であってもよく、1.0mol%以上であってもよく、1.5mol%以上であってもよい。一方、装飾膜の耐化学性に影響する有効成分(希土類元素、第1元素等)の含有量の相対的な低下を防止するという観点から、上記他の元素の含有量の上限は、3.5mol%以下が好ましく、3.0mol%以下がより好ましく、2.5mol%以下がさらに好ましく、2.0mol%以下が特に好ましい。
以上、ここに開示される装飾用組成物の貴金属元素とガラスマトリクス元素について説明した。なお、ここに開示される装飾用組成物は、上述した成分の他に、セラミックス製品の表面への定着性や装飾膜の成形性などを考慮して種々の成分を添加されていると好ましい。以下、ここに開示される装飾用組成物に含まれ得る他の成分について説明する。但し、以下で説明する他の成分は、ここに開示される技術の効果を著しく妨げない限りにおいて、装飾用組成物に使用され得る従来公知の成分を特に制限なく使用することができる。すなわち、ここに開示される装飾用組成物は、その用途等に応じて、上述した必須成分以外の成分を適宜変更することができる。
ここに開示される装飾用組成物は、セラミックス製品の表面に装飾膜を形成するために用いられる。かかる装飾膜は、セラミックス製品の表面に装飾用組成物を塗布(付与)した後に、所定の条件の焼成処理を実施することによって形成される。例えば、セラミックス製品の一例として、セラミックス基材の表面に、釉薬に由来するガラス膜が形成されたものが挙げられる。このようなセラミックス製品を対象とした場合、ここに開示される装飾用組成物は、ガラス膜の表面に装飾膜を形成する「上絵付け」用の絵具として使用される。この上絵付けでは、ガラス膜の表面に装飾用組成物を塗布した後、700℃~1000℃程度の温度の焼成処理を行うとよい。これによって、セラミックス製品の表面に装飾膜を形成できる。なお、ここに開示される装飾用組成物は、素焼きした生地(セラミックス基材)の表面に直接装飾を施す「下絵付け」用の絵具として使用することもできる。この下絵付けでは、セラミックス基材の表面に装飾用組成物を塗布した後、1200℃~1400℃程度の温度の焼成処理を行うとよい。これによって、セラミックス製品の表面に装飾膜を形成できる。
以下、ここで開示される技術に関する試験例を説明するが、ここに開示される技術をかかる試験例に限定することを意図したものではない。
