The hard coat layer may contain a cured product of a polyorganosiloxane compound having an alicyclic epoxy group.

The present invention relates to a prepreg, which includes: a fiber base material; and a resin composition containing a thermosetting resin (A) and spherical zinc molybdate (B), in which the fiber base material has a basis weight of 50 g/m.sup.2 or more, and a laminated plate, a printed wiring board, and a semiconductor package, each of which uses the prepreg.

Described herein are polyamides (PA) incorporating a cycloaliphatic monomer containing a cyclohexyl group. It was surprisingly discovered that by incorporating the cycloaliphatic monomer containing a cyclohexyl group, the resulting polyamides (PA) had significantly reduced water absorption and significantly increased Tg, while maintaining high Tm, Tc and good mechanical properties, relative to analogous polyamides free of the cycloaliphatic monomer and PA6,T based polyamides copolymerized with either or both of isophthalic acid and adipic acid.
