ABSTRACT:
A process for producing a polymer or a crosslinked article having a region in which the polymerization rate or crosslinking rate is varied is disclosed, comprising irradiating a photopolymerizable substance or photo-crosslinkable substance with laser light having an uneven distribution of intensity. The process is suitable for mass production of polymerization rate- or crosslinking rate-distributed articles. An arbitrary distribution pattern can be designed and formed under good control, and distribution regions having a fine shape can be formed with excellent precision. A plurality of distribution regions having a regular shape can be formed at a high density with high precision.
