Abstract
An optical polymeric material that can substantially block the transmission of ultraviolet light as well as selected portion of violet light. The polymeric material will include monomeric units of one or more lens monomers, and monomeric units of a monomer of formula (I).
Claims22
An optical polymer comprising:
- (a) monomeric units of one or more monomers suitable for producing optical polymeric materials and (b) monomeric units of a light-absorbing monomer having formula I
- wherein A is NH or NR;
- B is OH, NH2, or F;
- R1 and R2 are independently selected from the group consisting of H, Me, Et, i-propyl, t-butyl, F, Cl, Br, I, OH, OR, NH2, NH3+, NHR, NR2, NH2R+, NR3+, CN, C(O)OH, C(O)OR, C(O)R, Ar, OAr, SH, SR, S(O)OR, and D;
- wherein at least one of R1 and R2 is D;
- wherein Ar is an aromatic monovalent radical having 6-10 carbon atoms, and Ar comprises a single ring or a condensed ring system, optionally substituted;
- D is an aliphatic radical with twelve or fewer carbon atoms that includes an ethylenic polymerizable group and is optionally substituted with oxygen or nitrogen;
- and R is a C1-C6 alkyl.
