Patent ID: 8252512

Claim:
An epoxy adduct having a structure formed by adding an unsaturated monobasic acid to an epoxy compound according to formula (I): wherein X, Y, and Z are each independently selected from the group consisting of: an alkyl group having 1 to 10 carbon atoms and optionally having a methylene group in said alkyl group interrupted by an unsaturated bond, —O—, or —S—, an alkyl group having 1 to 10 carbon atoms and having at least one hydrogen atom substituted with a halogen atom, and optionally having a methylene group in said alkyl group interrupted by an unsaturated bond, —O—, or —S—, an aryl group having 6 to 20 carbon atoms and optionally having a methylene group in said aryl group interrupted by an unsaturated bond, —O—, or —S—, an aryl group having 6 to 20 carbon atoms and having at least one hydrogen atom substituted with a halogen atom, and optionally having a methylene group in said aryl group interrupted by an unsaturated bond, —O—, or —S—, an arylalkyl group having 7 to 20 carbon atoms and optionally having a methylene group in said arylalkyl group interrupted by an unsaturated bond, —O—, or —S—, an arylalkyl group having 7 to 20 carbon atoms and having at least one hydrogen atom substituted with a halogen atom and optionally having a methylene group in said arylalkyl group interrupted by an unsaturated bond, —O—, or —S—, a heterocyclic group having 2 to 20 carbon atoms, a heterocyclic group having 2 to 20 carbon atoms and having at least one hydrogen atom substituted with a halogen atom; and a halogen atom; X is either independently selected from said group from which Y and Z are independently selected or one X forms a ring structure with the other X, and said ring structure is optionally an aromatic ring; k, r, x and y are each independently a number of 0 to 4; a sum of x and y is 2 to 4; p is a number of 0 to 8; n is 0 to 10; and an optical isomer may exist when n is not 0.
