PURPOSE:To stably obtain a recording image having no dot density irregularity and sharp from low density to high density, by providing a layer consisting of pigment based on calcium carbonate and latex of a copolymer containing unsaturated carboxylic acid as one of monomer components in a specific wt.% range on a paper substrate. CONSTITUTION:Pigment to be used is based on calcium carbonate and generally used in a range of about 30-100 wt.%. As a copolymer to be used, a styrenic, butadiene type, methylmethacrylate/butadiene type, vinyl acetate type or acrylic copolymer containing about 5-25wt.% of unsaturated carboxylic acid as one of monomers is designated. This copolymer is usually applied to the surface of a base material in an amount of 5-60g/m<2> as a single adhesive in a latex form. As a result, the dispersion of a paint is improved and good transfer image aptitude is obtained. |
