Definitions
- the present invention relates to a resin composition, a pre-preda and a laminate.
- a laminated board using naphthalene-modified epoxy resin can achieve both solder heat resistance and a low linear expansion coefficient in the thickness direction (for example, Japanese Patent Application Laid-Open No. 5-3010941).
- naphthalene-modified epoxy resin has the disadvantage of poor adhesion to ⁇ conductor circuit metal.
- lead-free heat resistance is poor.
- An epoxy resin containing a dipentapentane-type epoxy resin and a resin composition containing a triazine-modified novolak resin can achieve solder heat resistance, a low linear expansion coefficient in the thickness direction, and adhesion to a conductor circuit metal (special Open 2 0 05-3 3 6 280).
- this resin composition is inferior in flame retardancy. Although flame retardancy can be achieved by increasing the nitrogen content, the lead-free heat resistance is reduced, so that both flame retardancy and lead-free heat resistance cannot be achieved.

- the laminated board of the present invention is characterized by being formed by molding one or more of the above-mentioned pre-preder.
- the resin composition of the present invention contains a naphthalene-modified epoxy resin.
- a naphthalene-modified epoxy resin As a result, the flame retardancy and solder heat resistance of the laminate can be improved, and the linear expansion coefficient can be lowered.
- an aromatic ring such as naphthalene modification is included, the energy between bonds between molecules increases and decomposition due to combustion becomes difficult to occur, resulting in flame retardancy. Therefore, the resin composition of the present invention can obtain an excellent flame retardant effect without adding a known flame retardant separately.
- the naphthalene-modified epoxy resin used in the resin composition of the present invention is not particularly limited, but an epoxy resin having a naphthalene skeleton represented by the following general formula (1) or (3) can be preferably used.
- n is an integer of 1 or more and 10 or less, preferably an integer of 8 or more and R is a hydrogen atom or a methyl group. If n exceeds 0, the viscosity of the resin will increase and impregnation into the substrate will deteriorate, which is preferable. It ’s not.

If the content of naphthalene-modified epoxy resin is less than the lower limit, the effect of improving heat resistance may be reduced, and if it exceeds the upper limit, the adhesion may be reduced.
- the epoxy resin other than the naphthalene-modified epoxy resin is not particularly limited.
- bisphenol A type epoxy resin, bisphenol F type epoxy resin, and the like can be used. It is preferable to use a brominated epoxy resin as the epoxy resin because it can be made flame retardant without deteriorating the properties of the epoxy resin.
- the resin composition of the present invention contains a triazine-modified novolak resin. As a result, the adhesion can be improved while maintaining the heat resistance.
- a novolak resin is used as a curing agent for naphthalene-modified epoxy.
- Use of novolak resin as a curing agent for naphthalene-modified epoxy resin is preferable because it does not deteriorate the excellent properties of naphthalene-modified epoxy resin such as water absorption and solder heat resistance.
- a cured product obtained by curing a naphthalene-modified epoxy resin with a novolac resin has a problem in that the adhesiveness of the copper foil is deteriorated because there are few polar groups in the resin.

Above, 30.0 parts by weight or less is preferable. If the content is less than the lower limit, the adhesiveness may be lowered, and if the content exceeds the upper limit, the water absorption rate may be deteriorated. In particular, by adjusting the content of the triazine-modified novolak resin to 24.8 parts by weight or more and 30.0 parts by weight or less with respect to 100 parts by weight of the epoxy resin, the adhesion of the cured resin can be reduced.
