<p>A shaped article is obtained by polymerizing a selectively reflective solution comprising a cellulose derivative and a polymerizable solvent. The cellulose derivative is a cellulose derivative having an alkyl degree of substitution of about 2.2 to 3, an acyl degree of substitution of about 0 to 0.8, and a total degree of alkyl and acyl substitution of about 2.8 to 3 Äe.g., a highly substituted alkyl cellulose (ethy cellulose) or an acylated alkyl cellulloseÜ. Moreover, the polymerizable solvent may be a (meth)acrylic monomer (e.g., (meth)acrylic acid)Ü. According to the present invention, there is provided a shaped article having selective reflectivity with respect to wavelength and circularly polarized light.</p> |
