A copolymerized crystalline latent catalyst including the reaction product of: (a) at least one crystalline acrylate monomer; (b) at least one copolymerizable catalyst compound; (c) at least one initiator; (d) at least one chain transfer agent; and (e) optionally, at least one solvent to provide a polymerized latent catalyst composition; and a process for making the above latent catalyst.

An antireflective film including: a support base, and a pattern composed of a photoresist material formed on the support base, the pattern having a larger size at a point closer to the support base. The photoresist material contains a polymer compound having an aromatic group, and the polymer compound includes at least one of: (i) a repeating unit having a cyclopentadienyl complex structure, (ii) a repeating unit having a naphthalene structure, and (iii) a repeating unit having a naphthalene structure and/or a fluorene structure. The repeating units having a naphthalene structure may include one of the following units: ##STR00001## The disclosed antireflective film shows an antireflection effect to decrease the reflection of light. A method of producing the antireflective film, and an eyeglass type display including the antireflective film are disclosed.
