Polymaleimide resin composition and laminate plate for semiconductor substrate using it

摘要

A polymaleimide resin composition is herein disclosed which comprises an aromatic amino resin (1), a polymaleimide resin (2) and a bifunctional crosslinking agent as components. The bifunctional crosslinking agent is preferably selected from an aliphatic diamine compound, a 2,4-diamino-S-triazine compound, a diisocyanate compound, and an aliphatic diamine compound plus a bismaleimide compound. A laminate plate for a semiconductor substrate in which the polymaleimide resin composition is used is also disclosed. According to the present invention, there can be provided a thermosetting resin composition which permits the preparation of prepregs and green sheets having excellent flexibility, so that the workability and the productivity of the laminate plates can remarkably be improved.
