Abstract
A recording material having a resin layer which contains a high concentration of a water-soluble resin such as polyvinyl alcohol, and which has excellent gas blocking property and flatness. Image defects such as non-uniform color and the like do not arise at the recording material. The recording material has, on a support, a recording layer which can form color due to application of heat and/or pressure thereto. At least one resin layer is provided between the support and the recording layer. The resin layer is formed by coating a low viscosity coating solution, and easily forms a flat surface by leveling.
Claims20
A recording material comprising:
- a support;
- a recording layer capable of forming color due to application of at least one of heat and pressure thereto;
- and
- between the support and the recording layer, at least one resin layer containing polyvinyl alcohol, wherein the resin layer contains water swellable synthetic mica.
A recording material comprising:
- a support;
- a recording layer capable of forming color due to application of at least one of heat and pressure thereto;
- and
- between the support and the recording layer, a resin layer formed by coating a coating solution including polyvinyl alcohol dissolved in a mixed solvent comprising another alcohol and water, wherein solvent ratio of the another alcohol to the water is at most 1 by mass in the solvent, wherein the coating solution further includes water swellable synthetic mica.
A recording material according to wherein the viscosity at 40° C. of the coating solution is from 5 to 100 mPa·s.
A recording material comprising:
- a support;
- a resin layer including polyvinyl alcohol formed on the support;
- and
- a recording layer formed on the resin layer,
- wherein the resin layer is formed by a process including the steps of dissolving polyvinyl alcohol in a mixed solvent of water and alcohol to produce a polyvinyl alcohol solution, adding methanol to the polyvinyl alcohol solution to adjust viscosity thereof to a desired viscosity, adding a water swellable synthetic mica, coating the support with a layer of a solution, and drying the layer.
