ABSTRACT:
A laminated transparent paper is disclosed therein which is obtained by laminating transparent papers on both the surfaces of a transparent polyester film via an adhesive, the surfaces of the transparent papers having coating layers of a coating solution mainly comprising an aqueous dispersion of at least one selected from the group consisting of an acrylonitrile-vinylformal-acrylic acid ester copolymer, a styrene-acrylic acid copolymer and a styrene-methacrylic acid copolymer, the laminated transparent paper having a Bekk smoothness of 20 seconds or more and an opacity of 45% or less. The laminated transparent paper permits obtaining precise printing without feathering when printing is made by the seal of a stamp ink or by a plotter or a printer of an ink jet system, suppresses the formation of roughness on a paper surface after the printing and drying, inhibits the deterioration of strength such as tearing strength at the time of heat fixing in a copying operation by an electrophotography system, and prevents blister from occurring owing to the separation of an adhesive layer.
