| titleOfInvention | Ultraviolet-absorptive polymer material |
| abstract | This new ultraviolet-absorptive polymer material comprises a copolymer between a methacrylic ester monomer and another vinyl monomer. The vinyl monomer has a colour-forming group having an absorption peak which is different from that of the methacrylic ester monomer. The absorption peak of the colour forming group of the vinyl monomer is specified to be around 249 nm.. The limiting viscosity(eta) of the copolymer lies between 1 x 10 power 2 and 4 x 10 power 3 cp.. The methacrylic ester is specified to have an ester group the carbon number of which is 1-4 and preferably a methacrylic methyl ester. The colour forming group of the vinyl monomer is preferably an aromatic ring or a hetero-aromatic ring. The vinyl monomer can be selected from among vinyl biphenyl, vinyl pyridine, vinyl naphthalene and N-vinyl carbazole. The mole ratio of the methacrylic ester monomer to the vinyl monomer lies between 10:1 and 10 power 3:1. The transmittance of the ultraviolet-absorptive polymer material at the wavelength 249 nm is 10% or less. The polymer is synthesised by a plasma-initiating polymerisation using a polymerisation initiator. A photo-resist can be made of the above mentioned polymer material using an excimer laser as a light source. |
