摘要:
An ultraviolet-absorptive polymer material which comprises a copolymer between a methacrylic ester monomer and other vinyl monomer having a color-forming group showing an absorption peak different from that of the methacrylic ester in the ultraviolet wavelength region. This polymer material is useful as a resist material showing a high etching effect and a high resolution.
