专利汇可以提供Pressure sensitive recording system and method of providing a split image therefor专利检索，专利查询，专利分析的服务。并且Corresponding images (an image and a mirror image thereof) are provided on adjacent surfaces of two sheets. An encapsulated liquid reactant precursor is supported on one of the surfaces and a co-reactant is coated on the other surface. The adhesion/cohesion characteristics of the co-reactant coating are so adjusted and selected that upon pressure-effected rupture of the particular capsules used, some of the co-reactant (as well as some precursor) physically transfer and the balance of each remains in situ and does not transfer. Substantially identical chemical reactions are thus produced concurrently on both adjacent surfaces to provide corresponding colored images thereon. If the upper one of the sheets is translucent, as in a typical gasoline credit set, the mirror image formed on the underside thereof by one of the chemical reactions will be viewable from the top side thereof as a right-readable image upon separation of the sheets.，下面是Pressure sensitive recording system and method of providing a split image therefor专利的具体信息内容。

权利要求

1. A PRESSURE-SENSITIVE RECORDING SYSTEM COMPRISING ONE SHEET HAVING A SURFACE SUPPORTING A MULTITUDE OF MICROSCOPIC PRESSURE-RUPTURABLE CAPSULES CONTAINING A REACTANT SOLUTION COMPRISING A CHEMICALLY REACTIVE DYE PRECURSOR AND A SOLVENT, AND A DIFFERENT SHEET HAVING A SURFACE SUPPORTING A PARTIALLY RELEASABLE CO-REACTANT ADAPTED, UPON APPLICATION OF A LOCALIZED PRESSURE TO THE SHEETS AND CONSEQUENT RUPTURE OF THE CAPSULES WHILE THE SURFACES ARE SUPERIMPOSED IN INTIMATE CONTACT, TO CAUSE SOME OF THE CO-REACTANT AND SOME OF THE CAPSULES AND REACTANT SOLUTION TO REMAIN IN SITU ON THEIR RESPECTIVE SUPPORTING SURFACES AND THE REMAINDER OF EACH TO PHYSICALLY TRANSFER TO THE ADJACENT

2. A system according to claim 1, the reactant solution comprising a precursor taken from the class of dithiooxamide and its N,N''di-substituted derivatives, and the co-reactant comprising by weight, when dried, about 22-37 percent nickel (II) chloride; about 9-21 percent zinc resinate; about 31-45 percent lithium stearate; and about 5-19 percent sodium benzoate.

3. A system according to claim 1, wherein the co-reactant comprises by weight, when dried, essentially about 55 percent propyl gallate; 6 percent tannic acid; 6 percent polyvinylpyrrolidone; 16 percent oxazoline wax; and 17 percent silica.

4. A system according to claim 1, wherein the co-reactant comprises by weight, when dried, essentially about 27 percent zinc resinate; 27 percent propyl gallate; 9 percent tannic acid; and 37 percent colloidal silica.

5. A system according to claim 1, wherein the solution comprises a precursor taken from the class of dithiooxamide and its N,N''di-substituted derivatives, and the co-reactant comprises nickel (II) chloride, zinc resinate, lithium stearate and sodium benzoate.

6. A system according to claim 1, wherein the co-reactant comprises by weight, when dried, 22-37 percent nickel (II) chloride; 9-21 percent zinc resinate; 31-45 percent lithium stearate; and 5-19 percent sodium benzoate.

7. A system according to claim 1, wherein the solution comprises a precursor taken from the class of dithiooxamide and its N,N''di-substituted derivatives, and the co-reactant comprises by weight, when dried, essentially about 31 percent nickel (II) chloride; 15 percent zinc resinate; 39 percent lithium stearate and 15 percent sodium benzoate.
