Abstract:
An epoxy resin composition comprising(a) an epoxy resin or epoxy resin mixture containing on average more than one 1,2-epoxide group in the molecule,(b) core/shell particles comprising a core comprising an elastomer having a T.sub.G value of <0.degree. C. onto which a shell of a crosslinked copolymer is grafted, wherein the shell comprises at least one (meth)acrylate of formula I ##STR7## derived from polyethylene glycol or polypropylene glycol, in which either R.sub.2 or R.sub.3 is the radical ##STR8## and the other radical is --H or alkyl, R.sub.1 and R.sub.4 are each --H, --CH.sub.3, or --C.sub.2 H.sub.5, and n is a number from 2 to 30, where the proportion of the crosslinking component in the copolymer of the shell is from 6 to 60% by weight, based on the total amount of the comonomers in the shell copolymer, and(c) a curing agent or a curing catalyst for the epoxy resin component (a).
