摘要:
A coating composition comprises: a fluoroaliphatic group-containing copolymer comprising a repeating unit A corresponding to a fluoroaliphatic group-containing monomer and a repeating unit B corresponding to at least one monomer, wherein a material obtained by polymerization of only the repeating unit B exhibits a glass transition point of 300K or more. A coating composition comprises: a fluoroaliphatic group-containing copolymer comprising a repeating unit A corresponding to a fluoroaliphatic group-containing monomer and a repeating unit B corresponding to at least one monomer, wherein the fluoroaliphatic group-containing copolymer exhibits a glass transition point of 273K or more.
摘要:
An antireflective layer comprising a plurality of functional layers having different refractive indexes, the plurality of functional layers including a lowre fractive index layer containing a fluorine-containing copolymer, wherein the low refractive index layer further contains a polymer having a polymer graft part containing a polysiloxane segment represented by the following formula [1] in a side chain of the polymer: wherein R1 and R2 may be same or different and each represents a hydrogen atom, an alkyl group or an aryl group; and p is an integer of from 10 to 500.
