Abstract
A stain disappearing laminate of the present invention comprises a sebum absorption and diffusion layer 3 and a sebum attachment inhibition layer 2 laminated on a base material in this order. The sebum attachment inhibition layer 2 repels sebum 5 and reduces attachment of the sebum, as well as allows attached sebum to pass through to the sebum attachment inhibition layer side, and the sebum absorption and diffusion layer 3 absorbs the sebum 5 passed through the sebum attachment inhibition layer 2 and diffuses the sebum within the sebum absorption and diffusion layer itself.
