SUPPORTER FOR THERMAL MIGRATORY TYPE THERMAL TRANSFER RECORDING IMAGE-RECEIVING MATERIAL

摘要

PURPOSE:To prevent the generation of the transfer missing and density unevenness of a printing section by bringing film-thickness nonuniformity index value measured by using an optical type displacement sensor to a specific value or less and center-plane mean roughness SRa measured by employing a feeler type three-dimensional surface roughness meter to a specific value or less in paper as a substrate. CONSTITUTION:In the title supporter, in which paper mainly comprising natural pulp is used as a substrate and a paper substrate surface on one image-receiving side of paper is covered with a polyolefin resin, a film-thickness nonuniformity index Rp in the specified paper-making direction is brought to 1.65mV or less and center-plane mean roughness SRa in the paper-making direction in overall wavelength regions measured by using a feeler type three-dimensional surface roughness meter is brought to 1.3mum or less in paper as the substrate. Accordingly, the excellent supporter for a thermal migratory type thermal transfer recording image-receiving material, in which the transfer missing and density unevenness of a printing section are not generated and from which high gloss feeling is acquired visibly, can be obtained.
