PROBLEM TO BE SOLVED: To obtain a resin composition for prepreg, which has improved impregnating ability and resin flow, reduces dusting and has heat resistance and prepreg using the same. SOLUTION: The resin composition for prepreg comprises a mixed epoxy resin of 50-90 parts wt. of a solid epoxy resin and 10-50 parts wt. of a liquid epoxy resin, rubber and a curing agent in which 5-60 parts wt. of the rubber is mixed with 100 parts wt. of the mixed epoxy resin and 1-100 parts wt. of the curing agent is mixed with 100 parts wt. of the mixed epoxy resin. A phenoxy resin may be used as a substitute for the rubber. The amount of the phenoxy resin mixed is 5-200 parts wt. based on 100 parts wt. of the mixed epoxy resin. COPYRIGHT: (C)2005,JPO&NCIPI
