Description
乾燥ゾーンの温度は25℃〜140℃が好ましく、乾燥ゾーンの前半は比較的低温であり、後半は比較的高温であることが好ましい。ただし、各層の塗布組成物に含有される溶剤以外の成分の揮発が始まる温度以下であることが好ましい。例えば、紫外線硬化樹脂と併用される市販の光ラジカル発生剤のなかには120℃の温風中で数分以内にその数10%前後が揮発してしまうものもあり、また、単官能、2官能のアクリレートモノマー等は100℃の温風中で揮発が進行するものもある。そのような場合には、前記のように各層の塗布組成物に含有される溶剤以外の成分の揮発が始まる温度以下であることが好ましい。
次に、本発明のスライド塗布装置10の実施例を説明する。スライド塗布ホッパー12の構造は図1〜図3で示したものと同様である。
Claims (3)
