ABSTRACT:
A resist material curable by irradiation with high energy radiation such as electron beams, X-rays, ion beams, neutron beams, .gamma.-rays or deep ultraviolet light but substantially non-curable by irradiation with light having a wavelength of about 300 nm or more, the resist material comprising, as a main component, a solvent-soluble polymer containing an ethylenically unsaturated double bond, the polymer being obtained by reacting (a) a polymer having a plurality of oxirane rings therein and (b) a monomer containing (i) at least one ethylenically unsaturated double bond and (ii) one functional group capable of opening the oxirane rings, and then opening the unreacted oxirane rings.
