First claim

Opening claim text (preview).

What is claimed is: 1. A silicone-modified epoxy resin represented by the following formula (1): wherein R 1 represents an alkylene group having 2 to 6 carbon atoms and optionally containing an ester or ether bond; R 2 represents a monovalent aliphatic hydrocarbon group having 1 to 6 carbon atoms or a monovalent aromatic hydrocarbon group having 6 to 12 carbon atoms; R 3 represents an oxygen atom or a phenylene group; k represents 1 to 10 as an average value; m represents an integer of 0 to 2; n represents an average value between greater than 0 and 10; and a plurality of groups R 1 , R 2 , R 3 , k, or m present in the formula may be the same or different from each other, and wherein the silicone-modified epoxy resin is obtained by reacting compounds represented by the following formulas (2), (6), and (8): wherein m is as defined above; and R 4 represents an alkylene group having 0 to 4 carbon atoms and optionally containing an ester or ether bond, wherein R 2 , R 3 , and k are each as defined above, and wherein m and R 4 are each as defined above. 2. An epoxy resin composition comprising (A) a silicone-modified epoxy resin according to claim 1 and (B) an epoxy resin curing agent. 3. The epoxy resin composition according to claim 2 , further comprising (C) an epoxy resin curing catalyst. 4. The epoxy resin composition according to claim 2 , wherein the epoxy resin curing agent is selected from an amine curing agent, a phenol curing agent, an acid anhydride curing agent, and a polyvalent carboxylic acid resin. 5. A cured article obtained by curing an epoxy resin composition according to claim 2 .
