Abstract
Abstract A process for preparing color-developer coatings in which an oily solution of an acidic, organic material is emulsified in water and an insoluble, particulate, oil-adsorbent material is dispersed in the emulsion. The resulting emulsion-dispersion may be coated onto a receptor such as a paper substrate or other receiving surface and dried. The product resulting from the process is an enhanced color-developer coating for use in pressure-sensitive copy systems.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
72 words
A process for preparing a color-developer coating which comprises mixing an oily solution of an acidic organic acceptor material capable of developing a color when contacted with a basic chromogenic material in a water-immiscible organic liquid, an aqueous solution of an emulsifier, and an insoluble, particulate, oil-adsorbent extender to form an emulsion-dispersion comprising a dispersion of said particulate oil-adsorbent extender in an oil-in-water emulsion of said oily solution in said aqueous solution.
Claim 2
Dependent Claim
72 words
A process for preparing a color-developer coating which comprises mixing an oily solution of an acidic organic acceptor material capable of developing a color when contacted with a basic chromogenic material in a water-immiscible organic liquid, an aqueous solution of an emulsifier, and an insoluble, particulate, oil-adsorbent extender to form an emulsion-dispersion comprising a dispersion of said particulate oil-adsorbent extender in an oil-in-water emulsion of said oily solution in said aqueous solution.
Claim 3
Dependent Claim
41 words
A process as recited in claim 1 wherein said oily solution of acidic organic acceptor material is mixed under shear with the aqueous solution of emulsifier to form said oil-in-water emulsion prior to the addition of said insoluble, particulate, oil-adsorbent extender.
Claim 4
Dependent Claim
34 words
A process as recited in claim 1 wherein said insoluble, particulate, oil-adsorbent extender is admixed with said aqueous solution of emulsifier prior to the addition of said oily solution of acidic organic acceptor material.
Claim 5
Dependent Claim
31 words
A process recited in claim 1 wherein said insoluble, particulate, oil-adsorbent is admixed with said oily solution of acidic organic acceptor material prior to mixing with the aqueous solution of emulsifier.
Claim 6
Dependent Claim
20 words
A process as recited in claim 1 including the further step of adding a supplementary adhesive material to said emulsion-dispersion.
Claim 7
Dependent Claim
23 words
A process as defined in claim 1 wherein said insoluble, particulate, oil-adsorbent extender is inert with respect to said acidic organic acceptor material.
Claim 8
Dependent Claim
21 words
A process as defined in claim 1 wherein said insoluble, particulate, oil-adsorbent extender is reactive with said acidic organic acceptor material.
Claim 9
Dependent Claim
63 words
A process for preparing a color-developer coating which comprises mixing an oily solution of an acidic organic acceptor material in a water-immiscible organic liquid, an aqueous solution of an emulsifier, and a particulate reactive compound capable of reacting with said acidic organic material to form a dispersion of the reaction product in an oil-in-water emulsion of said oily solution in said aqueous solution.
Claim 10
Dependent Claim
63 words
A process for preparing a color-developer coating which comprises mixing an oily solution of an acidic organic acceptor material in a water-immiscible organic liquid, an aqueous solution of an emulsifier, and a particulate reactive compound capable of reacting with said acidic organic material to form a dispersion of the reaction product in an oil-in-water emulsion of said oily solution in said aqueous solution.
Claim 11
Dependent Claim
30 words
A process as recited in claim 8 wherein said reactive compound is admixed with said oily solution of acidic organic material prior to emulsification in the aqueous solution of emulsifier.
Claim 12
Dependent Claim
30 words
A process as recited in claim 8 wherein an insoluble, particulate, oil-adsorbent extender is added to said mixture to form a dispersion of said particulate, oil-adsorbent extender in said mixture.
Claim 13
Dependent Claim
23 words
A process as defined in claim 10 wherein said insoluble, particulate, oil-adsorbent extender is inert with respect to said acidic organic acceptor material.
Claim 14
Dependent Claim
21 words
A process as defined in claim 10 wherein said insoluble, particulate oil-adsorbent extender is reactive with said acidic organic acceptor material.
Claim 15
Dependent Claim
53 words
A coating product prepared by mixing an oily solution of an acidic organic acceptor material in a water-immiscible organic liquid, an aqueous solution of an emulsifier, and an insoluble, particulate, oil-adsorbent extender to form a dispersion of said particulate, oil-adsorbent extender in an oil-in-water emulsion of said oily solution in said aqueous solution.
Claim 16
Dependent Claim
53 words
A coating product prepared by mixing an oily solution of an acidic organic acceptor material in a water-immiscible organic liquid, an aqueous solution of an emulsifier, and an insoluble, particulate, oil-adsorbent extender to form a dispersion of said particulate, oil-adsorbent extender in an oil-in-water emulsion of said oily solution in said aqueous solution.
