Abstract
PURPOSE:To prevent a film from exfoliating when high pressure is applied thereto, by using a substrate which is a synthetic resin sheet having a porous absorbent surface layer whose oil absorption measured by a prescribed method is 500 seconds or less. CONSTITUTION:Microcapsules containing an achromatic coupler and a developer, which reacts with the capsules to develop a color, are provided on a synthetic resin sheet having a porous absorbent surface layer whose oil absorption measured by a method complying with JIS-8130-1963 is 500 seconds or less. If the oil absorption were more than 500 seconds, the adhesive power of the coupler layer and the developer layer to the synthetic resin sheet as a substrate would be lower. In that case, enough adhesive power could not be obtained without surface treatment. The film on the synthetic resin sheet does not exfoliate even if high pressure is applied to them.
