・接合に適した光硬化型接着剤に関する。Detailed Description of the Invention [Field of Industrial Application] The present invention is a photocurable adhesive that is made of an epoxy base resin and an epoxy reactive diluent, has excellent water resistance, and can easily control shrinkage during curing. The present invention relates to a photo-curable adhesive that is particularly suitable for fixing and bonding minute electronic and optical components that require precise alignment, since the curing shrinkage rate can be reduced to 2% or less.

されているが、硬化し難く、紫外線を用いた硬化は極め
て難しく、実用的でない。Even epoxy adhesives, which are known as adhesives with the lowest curing shrinkage rate, exhibit curing shrinkage of 3 to 5%. Conventionally, in order to improve this point, adhesives are known in which an epoxy resin is used as a base resin and a large amount of an inorganic filler is added, and several of these are commercially available. However, even with these adhesives, the amount of shrinkage during curing is as large as 2 to 3%, and there is still no adhesive that can join and fix minute electronic and optical components with precision on the order of microns or less. Furthermore, adhesives containing large amounts of inorganic fillers have high viscosity and are difficult to use. Also,
When using subiro-ortho resin, the shrinkage during curing goes from zero to negative, so adhesives using this resin have been proposed, but they are difficult to cure and extremely difficult to cure using ultraviolet light, making them impractical. .
また、従来の接着剤は、耐久性が十分でなく、長期信頼

本発明の目的は、上記のような欠点のない硬化収縮率制
御光硬化型接着剤を提供することにある。An object of the present invention is to provide a photocurable adhesive with controlled curing shrinkage rate that does not have the above-mentioned drawbacks.

ントロールできることを見出した。In order to solve the above problems, the present inventor investigated a method of controlling the shrinkage of the cured product by foaming during photocuring, and found that it is a method that has been previously proposed as a photopolymerization initiator and that controls foaming during curing. By incorporating diazonium salt, which is currently not used at all, the shrinkage rate during curing can be controlled to any value with good reproducibility by generating nitrogen gas from the diazonium salt and causing appropriate foaming during photocuring.

The contradictory problems of storage stability and adhesive-promoting curing (which only occurs when the silane compound is silanolized) could be resolved by appropriate formulation. In other words, since an onium salt-based photopolymerization initiator is used, upon irradiation with ultraviolet rays, the Brønsted acid generated from the onium salt progresses the reaction of the epoxy group, and the silane coupling agent is activated (the alkoxysilane group is hydrolyzed). The silanol group is bonded to the reactive group (eg, hydroxyl group, etc.) on the surface of the adherend and the epoxy resin, increasing the bonding strength at the adhesive interface. On the other hand, when stored in a container that is not exposed to ultraviolet rays, silane is less likely to be activated and has good storage stability.

。The blending ratio of the diazonium salt is preferably in the range of 0.05 to 0.3 parts by weight. If it is less than 0.05 parts by weight, there is almost no decrease in shrinkage rate due to foaming. Moreover, if the amount exceeds 0.3 parts by weight, foaming during curing becomes large or increases, resulting in a decrease in performance such as mechanical properties, which poses a practical problem.
