As IJ preg, a crosslinked curable resin composition containing 95 to 5 wt% of a polyethylene resin composition containing 0.1 to 1 t% of organic peroxide and 5 to 95 wt% of a cyanate ester resin composition. A method for producing laminates such as laminates, copper-clad laminates, multilayer printed wiring boards, etc., characterized by using a sheet or a base composite sheet obtained by fusing the crosslinked curable resin composition to a base material. This invention provides laminates with excellent electrical properties, strength, and adhesive properties. Cross-linked polyethylene has improved heat resistance and durability compared to uncross-linked polyethylene. For example, polyethylene cross-linked by radiation is used as a coating for electric wires such as undersea cables, and it is also used when cross-linked with organic peroxides. Polyethylene is used in foams and the like, and its practical use as a resin for printed wiring boards is being considered to take advantage of its electrical properties.

However, as predicted from its molecular structure, cross-linked polyethylene resin still has insufficient bending strength even when combined with a base material, and in particular, the glass transition temperature measured by the torsional vibration method is about 50 qC, and it cannot be used at high temperatures. At the bottom, the bending strength was poor (for example, the bending strength of a laminated board was 9.4k9/fence at 100°C).

In addition, in the case of cross-linked polyethylene resin using organic peroxide, the adhesive strength not only with copper foil but also with other laminated materials may be insufficient, or even if the adhesive strength is sufficient, the steel foil may be etched. The surface of the substrate from which it has been removed often exhibits a gray or black-gray color, making it unsuitable as an electrical material. The present invention is a method for manufacturing laminates that solves the above-mentioned drawbacks. For example, the glass transition temperature is about 10 p0, 10
Bending strength at 0qo: 20k9/Iso or higher, copper foil adhesion strength: 1.8
A copper-clad laminate having a rating of k9/m or higher can be obtained.
