A photocurable composition for three-dimensional stereolithography which has a lower viscosity and from which a cured product having a high refractive index is obtained, and a three-dimensional object formed by using the composition. The composition is a photocurable composition for three-dimensional stereolithography containing a fluorene monomer, a carbazole monomer, a diluent monomer, and a photopolymerization initiator, the carbazole monomer being contained in an amount of less than 30 wt % with respect to the total amount of the fluorene monomer and the carbazole monomer, and the diluent monomer being contained in an amount of at least 20 wt % with respect to total solids.

Provided herein are processes for the generation of composite polymer materials utilizing a single resin. The processes utilize diffusion between a region undergoing a polymerization reaction preferentially polymerizing one monomer component and an unreactive region. Diffusion and subsequent/concurrent polymerization results in a higher concentration of the more reactive monomer component in the reacting region and a higher concentration of the less reactive monomer components in the unreactive region. The unreactive region may be later polymerized. In embodiments, photopolymerization is used and the regions are generated by a mask or other mechanism to pattern the light.

An anti-forgery color conversion film includes a photonic crystal structure whose color is converted by an external stimulus such as a breath. The photonic crystal structure includes a first refractive index layer including a first polymer exhibiting a first refractive index; and a second refractive index layer which is alternately laminated with the first refractive index layer and includes a second polymer exhibiting a second refractive index. A consumer who purchases an article including the color conversion film may easily distinguish the authenticity of the article.
