Abstract
Abstract The present invention provides a transfer paper for imparting stereographic pattern produced by transferring the specified pattern printed on a synthetic sheet to a release layer surface of a release paper formed of a base member and the aforementioned release layer provided on the surface thereof and a manufacturing method of the transfer paper characterized in that a releasable thermoplastic resin is extruded between the base material and the sheet on which the specified pattern has been printed, thereby transferring the pattern on the aforementioned printed sheet to the surface of the aforementioned thermoplastic resin, followed by cooling, and then, said printed sheet is peeled off and separated from the surface of said thermoplastic resin. Thus this invention makes it possible to provide at low price and with ease a transfer paper for imparting stereographic perspective patterns having various grades of lusters and tones in combination.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
111 words
A transfer paper for imparting a stereographic pattern formed by transferring a specific stereographic pattern printed on a synthetic resin sheet to a release layer of a release paper comprising a base material and said release layer provided thereupon, said synthetic resin sheet being formed of at least one member selected from the group consisting of polyesters, polyamides, polycarbonates, polyacetals and polypropylene, said base material being selected from the group consisting of paper, cloth, synthetic resin films, metal foils and laminates of metal foils and synthetic resins, and said release layer being formed of at least one member selected from the group consisting of poly-4-methylpentene-1, polypropylene, ethylene-propylene copolymer and silicone resins.
Claim 2
Dependent Claim
111 words
A transfer paper for imparting a stereographic pattern formed by transferring a specific stereographic pattern printed on a synthetic resin sheet to a release layer of a release paper comprising a base material and said release layer provided thereupon, said synthetic resin sheet being formed of at least one member selected from the group consisting of polyesters, polyamides, polycarbonates, polyacetals and polypropylene, said base material being selected from the group consisting of paper, cloth, synthetic resin films, metal foils and laminates of metal foils and synthetic resins, and said release layer being formed of at least one member selected from the group consisting of poly-4-methylpentene-1, polypropylene, ethylene-propylene copolymer and silicone resins.
Claim 3
Independent Claim
134 words
A method of manufacture of a transfer paper wherein a releasable thermoplastic resin is extruded between a base material and a printed sheet upon which a specified stereographic pattern has been printed, thereby transferring the pattern on said pattern sheet to the surface of said thermoplastic resin, followed by cooling, peeling-off and separating said printed sheet from the surface of said thermoplastic resin, and said synthetic resin sheet being formed of at least one member selected from the group consisting of polyesters, polyamides, polycarbonates and polypropylene said base material being selected from the group consisting of paper, cloth, synthetic resin films, metal foils, laminates of metal foils and synthetic resins, and said releasable thermoplastic resin being formed of at least member selected from the group consisting of poly-4-methypentene-1, polypropylene, ethylenepolypropylene copolymer and synthetic resins.
Claim 4
