Abstract
Description
図1は、本発明の実施の形態1におけるインモールド成形用フィルムの層構成を示している。本実施の形態におけるインモールド成形用フィルムは、図1に示すように、キャリアフィルム101と転写フィルム102で構成された連続フィルムである。
図5は、本発明の実施の形態2におけるインモールド成形用フィルムの拡大断面図、及びその拡大断面図の一部をさらに拡大した図である。図1と同じ要素には同じ符号をつけ、その説明を省略する。本発明の実施の形態2におけるインモールド成形用フィルムは、着色層108を挟む第1無機高分子層107、第2無機高分子層109内に多孔質フィラー301を含有する。本構成のインモールド成形用フィルムにすることで、より高温の射出樹脂を使用してもゲート流れが起こり難いインモールドフィルムとなる。その他の構成については、実施の形態1と同様であるため、詳細な説明を省略する。
