Abstract
Abstract A recording material which is produced through the reaction of two kinds of color formers, namely a metallosilane compound and a polyhydroxyphenol. According to the invention, clearly printed, typed or handwritten letters or figures are easily formed on a substrate, with an excellent fastness against light, heat, water, and chemicals, and with an excellent color tone.

Claim 3
Dependent Claim
65 words
A recording material as claimed in claim 1 wherein at least one of the colorformer compositions is enclosed into frangible microcapsules in an oil dispersion thereof and wherein both color-former compositions are coated each up on a surface of a substrate whereby they react to form an image upon rupture of said frangible microcapsules in areas where the energy is applied to rupture said microcapsule.
Claim 4
Dependent Claim
38 words
A recording material according to claim 1 wherein each colorformer composition is enclosed in frangible microcapsules as an oil dispersion thereof and both colorformer compositions in microcapsule form are coated together on the same surface of a substrate.
Claim 5
Dependent Claim
57 words
A recording material according to claim 1 wherein at least one colorformer composition is microencapsulated in an oil dispersion and each composition is coated upon a separate surface of separate substrates and the caoted surfaces are juxtaposed whereby a colored image is formed in areas of the juxtaposed surfaces where energy is applied to rupture said microcapsule.
Claim 6
Dependent Claim
45 words
A recording material as claimed in claim 1 wherein a substrate is coated with one of said colorformer compositions and the other of said colorformer compositions, in the form of a liquid or paste ink is applied, in printed image-forming areas, to the coated substrate.
Claim 7
Dependent Claim
72 words
A recording material as claimed in claim 1 wherein a paper substrate is coated with one of said colorformers and is in local contact with a porous substrate inpregnated with the other of said colorformers whereby said visual image is formed in areas where pressure is applied to said porous substrate to transfer said other colorformer to said paper substrate thereon to react with said one colorformer whereby an image is formed.
Claim 8
Dependent Claim
18 words
A recording material as claimed in claim 1 wherein the polyhydroxyphenol colorformer composition includes an antioxidant sulfur compound.
Claim 9
Dependent Claim
18 words
A recording material as claimed in claim 1 wherein the polyhydroxyphenol colorformer composition includes an acidic antioxidant material.
Claim 10
Dependent Claim
47 words
A recording material as claimed in claim 1 wherein at least one of said two colorformer compositions contains aT least one compound selected from the group consisting of water-insoluble amines, basic nitrogen compounds of the formulae I - Q and an alkylene carbonate of the formula R
Claim 11
Dependent Claim
65 words
A recording material as claimed in claim 9 wherein at least one of the colorformer compositions is enclosed into frangible microcapsules in an oil dispersion thereof and wherein both color-former compositions are coated each up on a surface of a substrate whereby they react to form an image upon rupture of said frangible microcapsules in areas where the energy is applied to rupture said microcapsule.
Claim 12
Dependent Claim
38 words
A recording material according to claim 9 wherein each colorformer composition is enclosed in frangible microcapsules as an oil dispersion thereof and both colorformer compositions in microcapsule form are coated together on the same surface of a substrate.
Claim 13
Dependent Claim
53 words
A recording material according to claim 9 wherein at least one colorformer composition is microencapsulated and each composition is coated upon a separate surface of separate substrates and the coated surfaces are juxtaposed whereby a color image is formed in areas of the juxtaposed surfaces where energy is applied to rupture said microcapsule.
Claim 14
Dependent Claim
45 words
A recording material as claimed in claim 9 wherein a substrate is coated with one of said colorformer compositions and the other of said colorformer compositions, in the form of a liquid or paste ink is applied, in printed image-forming areas, to the coated substrate.
Claim 15
Dependent Claim
72 words
A recording material is claimed in claim 9 wherein a paper substrate is coated with one of said colorformers and is in local contact with a porous substrate inpregnated with the other of said colorformers whereby said visual image is formed in areas where pressure is applied to said porous substrate to transfer said other colorformer to said paper substrate thereon to react with said one colorformer whereby an image is formed.
Claim 16
Dependent Claim
18 words
A recording material as claimed in claim 9 wherein the polyhydroxyphenol colorformer composition includes an antioxidant sulfur compound.
Claim 17
Dependent Claim
