Abstract:

A nearly colorless transparent plastic material usable as lens, filter and so forth, which can exhibit an antiglare effect without lowering the quantity of visible rays by using together a complex compound of a specified transition metal element and a dye or a pigment which absorbs a spectrum complementary to the absorption spectrum with a specified wavelength of the complex compound. The plastic material comprises a polymer prepared by polymerizing one or more polymerizable monomers in the presence of a polymerization initiator or catalyst, and the complex compound is represented by the general formula (A)nM, wherein A represents either a ligand selected from the group consisting of those giving chelate complexes having eight specified basic chemical structures and those giving organometallic complexes, or a ligand forming a cyclic ligand composed of nAs; M represents Sc, Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, or Lu; and n represents 2, 3 or 4 depending on the kind of element.
