Semi-cured body, the cured product, laminate, a manufacturing method of preparation and cure of the semi-cured body

It is possible to reduce the surface roughness of the roughening treated surface, further, when the metal layer is formed on the surface of the cured product after curing, it is possible to increase the adhesive strength between the cured body and the metal layer semi-cured body, to provide a laminate using the semi-cured product. Semi-cured body 1, an epoxy resin, a curing agent, a resin composition containing a surface-treated silica component following silica particles having an average particle diameter of 1μm is a silane coupling agent, for 24 hours at 23 ° C. in methyl ethyl ketone soaked gel fraction after is formed by roughening treating the reaction product was reacted as above 90%. Laminate comprises a cured body obtained by curing the semi-cured body 1, and a metal layer formed by plating on the surface of the cured resin. Adhesion strength between the cured body and the metal layer is 4.9 / cm or more.
