abstract |
The (meth)acrylate of the present invention is represented by the following formula (1). The (meth)acrylate can be produced by first producing a lactone by reducing an addition product obtained by the Diels-Alder reaction between 1,3-diene and maleic anhydride, and then hydrating the lactone to produce an alcohol followed by (meth)acrylation of the alcohol. A polymer produced by (co)polymerizing a monomer composition comprising the (meth)acrylate of the present invention is excellent in transparency, dry etching resistance, and solubility in organic solvents, and so it is preferably used as a resin for a chemically amplified resist composition. n n n wherein each of R 1 , R 2 , R 3 and R 4 represents a hydrogen atom, a methyl group or an ethyl group; either one of X 1 or X 2 represents a (meth)acryloyloxy group and the other represents a hydrogen atom; both A 1 and A 2 represent hydrogen atoms, or A 1 and A 2 form —O—, —CH 2 — or —CH 2 CH 2 —. |
