Thermosetting resins typified by epoxy resins are widely used in electric and electronic equipment parts due to their excellent properties, and when flame retardancy is imparted to ensure safety against fire. There are many. In order to make these resins flame-retardant, it has been customary to use halogen-containing compounds such as brominated epoxy resins. Although these halogen-containing compounds have a high degree of flame retardancy, aromatic bromine compounds not only separate corrosive bromine and hydrogen bromide when they are thermally decomposed, but also have high toxicity when decomposed in the presence of oxygen. May form bromodibenzofuran and polydibromobenzoxine. In addition, it is difficult to dispose of old waste materials containing bromine. For these reasons, phosphorus compounds and nitrogen compounds have been investigated as flame retardants replacing bromine-containing flame retardants.

As mentioned above, flame retardancy can be realized by phosphorus compounds and nitrogen compounds. The mechanism is
Nitrogen compounds accelerate the decomposition and thermal condensation of phosphorus compounds to form polyphosphoric acid, and the generated polyphosphoric acid forms a film on the surface of the epoxy resin, producing adiabatic effect and oxygen barrier effect, and as a result, preventing combustion. It is a thing. As a nitrogen compound used for flame retardation, it is well known that triazine-modified novolac has excellent flame retardancy and is an excellent compound.

When a triazine-modified phenol novolac resin is used as a curing agent for epoxy, it tends to absorb moisture. In addition, phosphorus compounds are generally liable to absorb moisture, and the moisture absorption lowers solder heat resistance. For this reason, the amount of nitrogen and phosphorus contained in the resin should be as small as possible, but when a commonly used bisphenol A epoxy resin is used, the flame retardancy decreases when the nitrogen and phosphorus contents are reduced. .

DISCLOSURE OF THE INVENTION The present invention has been made as a result of studies aimed at solving such a problem. By using a novolak epoxy resin having high heat resistance as an epoxy resin, a small amount of nitrogen can be removed. Flame retardancy can be realized with phosphorus, and it has excellent heat resistance against moisture absorption solder. Also, by using a triazine-modified phenol novolac resin and a phosphorus atom-containing compound together, flame retardance is exhibited without using halogen due to the interaction between nitrogen and phosphorus. The present invention provides a resin composition having a high degree of flame retardancy, a prepreg using the same, and a laminate obtained from the prepreg.

As mentioned above, the (B) triazine-modified phenol novolac resin is useful as a nitrogen-based flame retardant for epoxy resins, but it easily absorbs moisture. In general, phosphorus compounds also tend to absorb moisture. Moisture absorption reduces solder heat resistance.

Generally, the (A) novolac epoxy resin has high heat resistance and a high benzene ring content, so that it is easily carbonized when thermally decomposed. Therefore, it has the feature of higher flame retardancy than bisphenol A epoxy. If a novolac epoxy resin is used as the epoxy resin, the amount of nitrogen and phosphorus contained in the resin can be made as small as possible. However, the cured product of novolac epoxy resin has a drawback that it becomes stiff due to a high crosslinking density. Therefore, in order to reduce the crosslink density, 1 functional group that reacts with the epoxy group
