PURPOSE:To prevent transmission of oxygen obstructing radical reaction and softening of a wall material when a hot pressure roller passes by a method wherein a microcapsule having an inner phase of which physical property is altered when light and heat energy are given and of a wall material composed of hardened matter of a specific compound is born on a base material. CONSTITUTION:A microcapsule composed of an inner phase of which physical property governing a transfer characteristic is changed when light and heat energy are given and of a wall material composed of hardened matter of one or over kinds of compounds selected from a group composed of a polymer which has structural units expressed by formulas (a), (b) as main components and in which a ratio of the number of (a) to the total number of the number of (a) and the number of (b) is 30 to 90%, a polymer which has structural units expressed by formulas (c), (d) and in which a ratio of the number of (c) to the total number of the number of (c) and the number of (d) is 40 to 90%, and a polymer which has a structural unit expressed by formula (e) as a main component and in which a ratio of the number of (e) of A being a hydroxyl group to the total number of (e) is 30 to 95%, is born on a base material. |
