Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 188 words
A process for printing a magnetic image to be recognized by a magnetic ink character reader on a receiving medium, which comprises the steps of: providing a heat-sensitive magnetic transfer element comprising a heat-resisting foundation and a heat-sensitive transferring layer provided on the foundation, said transferring layer comprising a ferromagnetic substance powder and a binder material, the amount of the ferromagnetic substance powder being from 30 to 97% by weight per the total amount of the transferring layer, the binder material consisting essentially of a member selected from the group consisting of a wax and a mixture of a wax and a thermoplastic resin, and the transferring layer having a melting temperature of 50° to 120° C.; superimposing the transfer element over a receiving medium so that the transferring layer of the element is brought to come into contact with the receiving medium; and applying the heat from a thermal head of a thermal printer to the transfer element whereby the portions of the transferring layer corresponding to the areas heated with the thermal head were melted and transferred onto the receiving medium to give a magnetic image.
Claim 2
Dependent Claim 188 words
A process for printing a magnetic image to be recognized by a magnetic ink character reader on a receiving medium, which comprises the steps of: providing a heat-sensitive magnetic transfer element comprising a heat-resisting foundation and a heat-sensitive transferring layer provided on the foundation, said transferring layer comprising a ferromagnetic substance powder and a binder material, the amount of the ferromagnetic substance powder being from 30 to 97% by weight per the total amount of the transferring layer, the binder material consisting essentially of a member selected from the group consisting of a wax and a mixture of a wax and a thermoplastic resin, and the transferring layer having a melting temperature of 50° to 120° C.; superimposing the transfer element over a receiving medium so that the transferring layer of the element is brought to come into contact with the receiving medium; and applying the heat from a thermal head of a thermal printer to the transfer element whereby the portions of the transferring layer corresponding to the areas heated with the thermal head were melted and transferred onto the receiving medium to give a magnetic image.
Claim 3
Dependent Claim 27 words
The process of claim 1, wherein the thickness of the foundation is from 3 to 40μ, and that of the transferring layer is from 2 to 25μ.
Claim 4
Dependent Claim 12 words
The process of claim 1, wherein said binder material is a wax.
Claim 5
Dependent Claim 30 words
The process of claim 3, wherein said wax is a member selected from the group consisting of carnauba wax, montan wax, paraffin wax, microcrystalline wax, bees wax and mixtures thereof.
Claim 6
Dependent Claim 18 words
The process of claim 1, wherein said binder is a mixture of a wax and a thermoplastic resin.
Claim 7
Dependent Claim 24 words
The process of claim 5, wherein said binder is a mixture of a wax, a styrene butadiene rubber and a saturated alicyclic hydrocarbon resin.
