Claims20
A curable epoxy resin composition comprising:
- (a) at least one epoxy resin comprising, based on the total epoxy resin weight, at least 50 wt % of an epoxy resin of Formula (I),
- wherein n is an integer from 0 to 10;
- R is a group selected from hydrogen, halogen, C1-C20 alkyl, C1-C20 alkoxy, C1 to C20 phenyl, C1-C20 benzyl, or C1-C20 phenoxy;
- R1 is —CH2— or
- and R2 is hydrogen or a C1-C20 alkyl group;
- (b) a curing agent;
- and
- (c) a carboxylic acid group containing reaction product of (i) a carboxylic acid or its anhydride compound, and (ii) an amphiphilic block copolymer having at least one anhydride-reactive group, at least one epoxy resin miscible block segment, and at least one epoxy resin immiscible block segment;
- wherein the curable epoxy resin composition upon curing has a clarity value of at least 30%.
