の貯蔵安定性は重要な特性の一つである。Epoxy resin-glass cloth copper-clad laminate is made by immersing glass cloth in a varnish containing epoxy resin mixed with a curing agent, reaction accelerator and solvent, and impregnating the varnish into the gaps between the individual fibers of the glass cloth. After squeezing and removing the extra varnish, the prepreg is dried to produce a prepreg, and the prepress is cut into a predetermined size, laminated, and laminated with copper foil. The storage stability of the prepreg manufactured through the above series of steps is one of important characteristics.

ことの少ないもの、しかもプレス成形時には急速に硬化
するという潜在性硬化剤が多く用いられる。In order to prevent a decrease in moldability due to long-term storage, among high-temperature curing type curing agents, those that hardly lower the fluidity of the prepreg and that are latent curing agents that rapidly cure during press molding are used.
このような潜在性硬化剤としてはジシアンジアミド、

とする。At this time, the usable solvents are limited, and dimethylformamide, ethylene glycol monomethyl ether,
Although ethylene glycol monoethyl ether and the like can be mentioned, all of them are solvents having a high boiling point, and therefore require a high drying temperature in order to remove the residual solvent after being impregnated into the base material and curing.

(発明が解決しようとする問題点) しかし、従来法による硬化剤溶液組成物は、 生物に対する毒性が強い 貯蔵安定性に欠けている エポキシ樹脂との混合において溶剤がエポキシ基と反
応してしまう という問題があった。(Problems to be solved by the invention) However, the curing agent solution composition by the conventional method is highly toxic to living organisms and lacks storage stability. When mixed with an epoxy resin, the solvent reacts with the epoxy group. There was a problem.
