Abstract

Recording medium comprising: a substrate; a first light-scattering layer supported by the substrate, containing first solid scattering particles with a first melting point; and several second solid scattering particles near the first light-scattering layer, wherein the second solid scattering particles have a second melting point lower than the first melting point; wherein the first light-scattering layer is porous and the second solid scattering particles are arranged such that, when melted, they fill spaces between the first solid scattering particles.
