    • A TTP comprising two substrates each provided with a transparent resistive-layer, and an insulating section formed on at least one of the transparent resistive-layers using an ultra violet curing resin or an electron beam curing resin. The glass transition temperature of the cured resin in the insulating section is not higher than 80° C., and the insulating section contains a methyl ethyl keton soluble component of not less than 5 weight % and not more than 80 weight %. Since the insulating section is cured at a low temperature, it may be formed on a plastic substrate whose heat-withstanding capability is low. The insulating section can be formed in any desired shape and it can be cured within a short curing time, which are quite advantageous properties for the production of TTPs in volume. The insulating section spreads only minimally during the curing operation, therefore the initial shape, if it is a fine pattern, can be well preserved. Since an acid, alkaline solution or organic solvent is not used for forming the insulating section in the present invention, TTPs thus manufactured are free from the safety problems on the production floor as well as the environmental hazards associated with the use of these chemicals. The same applies also to an electronic system that incorporates the TTP.
    • 一种TTP,其包括两个分别具有透明电阻层的基板和使用紫外线固化树脂或电子束固化树脂形成在至少一个透明电阻层上的绝缘部分。 绝缘部中的固化树脂的玻璃化转变温度不高于80℃,绝缘部分含有不小于5重量%且不大于80重量%的甲基乙基酮可溶成分。 由于绝缘部分在低温下固化,所以可以形成在耐热能力低的塑料基板上。 绝缘部分可以形成任何期望的形状,并且可以在短的固化时间内固化,这对于体积的TTP的生产是非常有利的特性。 绝缘部分在固化操作期间仅最小化,因此如果是精细图案,则初始形状可以很好地保持。 由于在本发明中不使用酸性,碱性溶液或有机溶剂来形成绝缘部分,因此制造的TTP没有生产地板上的安全问题以及与使用这些化学品相关的环境危害。 同样适用于包含TTP的电子系统。

    • A paste for via-hole filling is provided, and the paste comprises at least (a) 30-70 volume % of conductive particles whose average diameter ranges from 0.5 to 20 .mu.m and whose specific surface area ranges from 0.05 to 1.5 m.sup.2 /g, and (b) 70-30 volume % of resin comprising at least 10 weight % of epoxy resin comprising at least one epoxy group per molecule, in which the total amount of a hydroxyl group, an amino group and a carboxyl group is not more than 5 mol % of the epoxy group, and the epoxy equivalent ranges from 100 to 350 g/eq. The conductive paste for filling via-holes and a printed circuit board comprising thereof can be used to provide an inner-via-hole connection between electrode layers without using a through-hole plating technique. The conductive paste comprises a metallic particle such as copper, an epoxy resin, a hardener and a dispersant if necessary. The paste having low viscosity and low volatility is used to fill holes disposed in a laminated substrate. Then, this substrate is heated and pressurized together with copper foils on both sides to attain a printed circuit board where both sides are electrically connected by inner-via-hole.

    • In a magneto-optic disk, a protective coating is applied to the magnetic recording layer made from a composite comprising minute particles of an inorganic compound, a lubricant and a radical-polymerizable resin. The surfaces of the minute particles of the first type are coated with a surface coating agent which has a lyophilic property with the radical-polymerized resin and this surface coating prevents the minute particles from forming aggregates in the protective coating. Then, the surface of the protective coating becomes smooth. In another type of protective coating, two types of the minute particles are included. The surfaces of the minute particles of the first type are coated with a surface coating agent, while those of the second type remain not coated. Thus, the minute particles of the first kind are not liable to form aggregates in the protective coating, whereas those of the other kind may form aggregates. Although the aggregates decrease the smoothness of the protective coating, they can enhance the amount of the lubricant which can be incorporated in the coating.
    • 在磁光盘中,将保护涂层施加到由包含无机化合物的微粒,润滑剂和自由基聚合性树脂的复合物制成的磁记录层。 第一类型的微小颗粒的表面涂覆有与自由基聚合树脂具有亲液性质的表面涂层剂,并且该表面涂层防止微小颗粒在保护涂层中形成聚集体。 然后,保护涂层的表面变得光滑。 在另一种类型的保护涂层中,包括两种类型的微小颗粒。 第一类型的微小颗粒的表面涂覆有表面涂层剂,而第二种颗粒的表面保持不被涂覆。 因此,第一种的微小颗粒在保护涂层中不易形成聚集体,而另一种微粒可能形成聚集体。 尽管聚集体降低了保护涂层的平滑度,但是它们可以增加可以掺入涂层中的润滑剂的量。
