Method for manufacturing negative photopolymerizable compositions for forming microlens shapes and patterns and optical elements

Abstract

The objective of this invention is to provide a negative photopolymerizable composition for forming microlens-shaped patterns, which exhibits excellent sensitivity and post-exposure stability, and is capable of forming microlens-shaped patterns with uniform shape and excellent chemical resistance; and a method for manufacturing an optical element using the negative photopolymerizable composition. This invention employs a negative photopolymerizable composition for forming microlens-shaped patterns, which is used in the formation of a photosensitive layer in a method comprising: irradiating a photosensitive layer with KrF rays for KrF exposure; developing the exposed photosensitive layer by heating it to form a dot pattern containing a plurality of dots; and deforming the dots by heating them to form a microlens-shaped pattern containing a plurality of dots with microlens shapes. The composition includes a photopolymerizable compound (A) and a photosensitizer (B).
