膜印刷を行うために使用するゴムローラに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel rubber roller for thin film printing. More specifically, the present invention relates to a rubber roller used for thin film printing in offset proofing machines, letterpress printing machines, and the like.
近年、エレクトロニクスの発展に伴い、例えば半導体素

高分子薄膜が必要とされ用いられている。一般にこれら
の薄膜には厚さ100Å〜3000Åのものを形成して
使用されるが、その膜厚の均一性、パターンの形状寸法
精度は厳しく要求されている。In recent years, with the development of electronics, polymer thin films are required and used in electronic components such as insulating films for semiconductor devices and alignment films for liquid crystal display devices. These thin films are generally used with a thickness of 100 Å to 3000 Å, but the uniformity of the film thickness and the precision of the shape and size of the pattern are strictly required.

が低く高価なものとなっている。Conventionally, vacuum evaporation, spinner coating of organic/inorganic compound solutions, dipping, or blowing methods have been widely used as methods for forming these thin films, but masking methods have been used to pattern these thin films. The process is complicated, has low productivity, and is expensive because it has to rely on photoetching and photoetching methods.

あるからオフセット校正機を用いて印刷するに際しては
十分均一な膜厚が得られにくい。又、求める厚みの薄膜
を安定して印刷することが困難であった。As an improvement to these methods, there is a printing method, for example, the method described in Japanese Patent Application Laid-Open No. 55-37314, but this method uses an offset proofing machine used in lithographic offset printing to print a glass plate, etc. using a blanket cylinder provided with a relief plate. Since this method uses a polymer solution printing ink to form a polymer film on a printing material with a smooth surface, it has the following drawbacks. That is, since the polymer solution used for this purpose is a very low viscosity solution with a viscosity of 20,000 cp to 10 cp, it is difficult to obtain a sufficiently uniform film thickness when printing using an offset proofing machine. Furthermore, it was difficult to stably print a thin film of desired thickness.
何故なら、オフセット校正機においてはインキを練り、
展色するのにロール粘り方法が用いられるが、一般のオ
フセット印刷用インキに比べて極めて低粘度で粘着性の

して供給することが困難であり、よって定量的に安定し
た展色を行うことができないからである。This is because the offset proofing machine kneads the ink,
The roll viscosity method is used to spread the color, but because it uses a polymer solution with extremely low viscosity and low stickiness compared to general offset printing inks, it does not stick evenly and the ink flows out from the gap between the rolls. Therefore, it is not possible to make the color development uniform. Furthermore, it is difficult to constantly and quantitatively supply ink to the rolls, and therefore it is not possible to perform quantitatively stable color development.

発明を完成するに至った。The present applicant has previously proposed Japanese Patent Application No. 57-37021 and Japanese Patent Application No. 55-66741 to improve the drawbacks of the conventional method.
No. 1, Japanese Patent Application No. 57-74172, etc., and as a result of repeated research into rubber rolls used in these inventions that would allow a thin film with a more uniform thickness to be obtained, the present invention was completed.

This is a rubber roller for use.
以下、本発明を図面と共に詳細に説明する。Hereinafter, the present invention will be explained in detail with reference to the drawings.

As shown in the figure, the present invention provides a rubber plate 3 having excellent printability for ink containing an aprotic polar organic solvent as a main solvent, or a rubber plate 3 on the surface of an iron core 2 having an arbitrary roller shaft 1. It is provided by coating a plate 3 with a relief portion 4 formed thereon to an appropriate thickness.

Rubber that is suitable for printing with inks whose main solvent is acetylmorpholine, tetramethylurea, etc., either singly or as a mixture, such as 1) "solvent resistance", 2) "wettability", 3) "surface shape", etc. It is necessary to use plate material.

剤性が大きく好適である。Among these printability, the first printability is solvent resistance, that is, it is necessary to use a rubber plate material that has solvent resistance to the aprotic polar organic solvent, but it is necessary to use a rubber plate material that has solvent resistance to the aprotic polar organic solvent. Examples of rubber materials having properties include aliphatic and hydrocarbon rubbers, such as isoprene rubber, butadiene rubber, ethylene propylene rubber, butyl rubber, and the like. Among them, butyl rubber and ethylene propylene rubber are preferred because of their high solvent resistance.

1に各種ゴムの耐溶剤性についての測定結果を示す。The solvent resistance referred to here is determined by the so-called low degree of swelling, and it is desirable that the degree of swelling is 9% or less in weight increase when immersed in a solvent for 70 hours at 25°C. This is because if the weight increase is 9% or more, the surface of the rubber roller will swell and soften during continuous printing, causing pattern distortion on the rubber plate and printing accuracy becoming impossible. Table 1 shows the results of measuring the solvent resistance of various rubbers.

- N-N dimethylacetamide Next, in order to improve the wettability of the surface of the rubber plate material as the second printability, various additives such as fillers, colorants, reinforcing agents, etc. are added to the rubber material. These additives may be added as appropriate, such as zinc oxide, magnesium oxide, lead oxide, titanium oxide,
Metal oxides such as silicon dioxide, hydrated silicic acid, anhydrous silicic acid, silicic acid compounds such as lucium silicate and magnesium silicate, carbonate compounds such as lucium carbonate and magnesium carbonate, sulfuric compounds such as magnesium sulfate and calcium sulfate, magnesium hydroxide, Hydroxide compounds such as calcium hydroxide, carbons such as carbon black and graphite, various metal powders,
In addition to various pigments such as cobalt compounds, cadmium compounds, cyanide compounds, benzicine compounds, and anthraquinone compounds, there are also fine powders such as clay, talc, mica, kaolinite, kreitrite, asbestos, and quartz. Preferably, metal oxides, silicic acid compounds, and carbonate compounds are used alone or in combination. The surface tension of the rubber material can be improved by mixing these additives in an amount of 2 to 80% by weight based on the base rubber, but it is best to incorporate these additives in an amount of 10 to 80% by weight. Tables 2 and 3 show the measurement results of changes in surface tension and wetting with respect to the amount of additive added.

As shown in , 3, the relationship between the amount of additives added and wettability in the present invention varies depending on the ink solvent used, so the amount of additives mixed in can be selected as appropriate depending on the type of ink. However, in order to obtain complete wettability of the rubber roller surface, at least 40 dynes/c
Since it is necessary to use a solvent having a surface tension of m, the above-mentioned mixing amount is necessary, and especially when 30 to 60% by weight is added, excellent wettability can be obtained with all of the above-mentioned solvents. It becomes even more suitable.
なお、これら添加剤を80重量%以上添加するとゴムの
弾力性が低下し硬度が高くなり過ぎるのでよくない。It should be noted that adding more than 80% by weight of these additives is not good because the elasticity of the rubber decreases and the hardness becomes too high.

μ以下の凹凸が均一に分布している状態が最もよい。Next, the surface of the rubber plate material is polished in order to obtain the third printability, which is the shape of the surface of the rubber plate material, that is, the required surface smoothness, but the required surface roughness after polishing is 15μ or less. more preferably 15
It is best if the unevenness of μ or less is uniformly distributed.

一な薄膜が得られなくなるためである。This is because when the surface roughness of the rubber roller becomes 15 μm or more, it becomes difficult to control the amount of ink that adheres to the surface, and uneven film thickness tends to occur due to the influence of the shape of the rough unevenness, making it difficult to obtain a uniform thin film. This is because it disappears.

It can be easily obtained with a thickness of about 3,000 Å, can be easily patterned, has high dimensional accuracy, and is excellent in mass production, so it has great utility value.
