Abstract
The plastic polarized lens (10) of the present invention contains a polarized film (12) and layers (resin layers) (14a and 14b) comprising a thiourethane-based resin stacked over both surfaces of the polarized film (12), and the polarized film contains an organic coloring compound represented by the following general formula (1).
Claims33
A plastic polarized lens comprising:
- a polarized film and
- layers comprising a thiourethane-based resin stacked over both surfaces of the polarized film,
- wherein the polarized film contains an organic coloring compound represented by the following general formula (1):
- wherein A1 to A8 each independently represent a hydrogen atom, a halogen atom, a nitro group, a cyano group, a hydroxy group, an amino group, a carboxyl group, a sulfone group, a linear, branched, or cyclic alkyl group having 1 to 20 carbon atoms, an alkoxy group having 1 to 20 carbon atoms, an aryloxy group having 6 to 20 carbon atoms, a monoalkylamino group having 1 to 20 carbon atoms, a dialkylamino group having 2 to 20 carbon atoms, an aralkyl group having 7 to 20 carbon atoms, an aryl group having 6 to 20 carbon atoms, a heteroaryl group, an alkylthio group having 1 to 20 carbon atoms, or an arylthio group having 1 to 20 carbon atoms, or may form a ring other than an aromatic ring through a linking group, and M represents two hydrogen atoms, a divalent metal atom, a trivalent mono-substituted metal atom, a tetravalent di-substituted metal atom, or an oxy metal.
A method of producing a plastic polarized lens, comprising:
- producing a resin film containing an organic coloring compound represented by the following general formula (1);
- shaping the resin film to obtain a polarized film;
- fixing the polarized film in a lens casting mold in a state in which the polarized film is apart from the mold;
- injecting a monomer mixture into the space between both surfaces of the polarized film and the mold;
- and
- stacking layers comprising a thiourethane-based resin over both surfaces of the polarized film by polymerizing and curing the monomer mixture:
- wherein A1 to A8 each independently represent a hydrogen atom, a halogen atom, a nitro group, a cyano group, a hydroxy group, an amino group, a carboxyl group, a sulfone group, a linear, branched, or cyclic alkyl group having 1 to 20 carbon atoms, an alkoxy group having 1 to 20 carbon atoms, an aryloxy group having 6 to 20 carbon atoms, a monoalkylamino group having 1 to 20 carbon atoms, a dialkylamino group having 2 to 20 carbon atoms, an aralkyl group having 7 to 20 carbon atoms, an aryl group having 6 to 20 carbon atoms, a heteroaryl group, an alkylthio group having 1 to 20 carbon atoms, or an arylthio group having 1 to 20 carbon atoms, or may form a ring other than an aromatic ring through a linking group, and M represents two hydrogen atoms, a divalent metal atom, a trivalent mono-substituted metal atom, a tetravalent di-substituted metal atom, or an oxy metal).
A polarized film comprising a resin containing an organic coloring compound represented by the following general formula (1):
