...(3) Photopolymerization type photosensitive resin There are various types, but basically they utilize the change in physical properties (solubility in solvents) that occurs when unsaturated polymers or vinyl monomers are polymerized by irradiating them with light. This type can harden layers several millimeters thick, so it is most often used for resin letterpress printing materials (the resin itself is used as the plate, and is generally called a photosensitive resin plate). In addition, even in fields that do not require image formation, they are also used in ultraviolet-curing inks and ultraviolet-curing paints from the standpoint of workability and non-pollution. ... *Some of the terminology that refers to "photosensitive resin plate" is listed below.

…(3)光重合型感光性樹脂 種々のタイプのものがあるが,基本的には不飽和ポリマーやビニルモノマーに光を照射して重合させる際に起こる物性(溶剤に対する溶解度)の変化を利用するものである。この型のものは,数mmの厚さの層を硬化させることができるので,樹脂凸版版材に応用されることが最も多い(樹脂そのものが版として用いられ,一般にこれを感光性樹脂版という)。このほか,画像形成を必要としない分野でも,作業性,無公害の見地から,紫外線硬化インキや紫外線硬化塗料にも応用されている。… ※「感光性樹脂版」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
