Description
即ち、本発明によれば、積層シートを各位置で交互に搬送方向を異ならせながら上流側又は下流側まで往復搬送させるので、パスラインの調整が高さ方向や左右方向で自在に可能になる。これにより、省スペース化を図りつつ、パスラインを長くすることできるので、設備コストの低減も可能になる。また、パスラインの延長が可能になるので、低照度で長時間の光照射を可能にし、生産効率の向上が図れる。
(a)(メタ)アクリル酸エステルを主成分とするアクリル系モノマーと、該アクリル系モノマー100重量部に対して、
(b)(メタ)アクリル酸エステル成分単位を主構成単位とし、重量平均分子量が50000以上である高分子量ポリマー成分5〜200重量部
(c)光重合開始剤0.01から5重量部
(d)架橋剤
とを含有し、実質的に溶媒を含有しない組成物が挙げられる。
