Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
148 words
A process for producing a transfer sheet having a transferable coating on said transfer sheet, said transfer sheet for use in producing master sheets by localized, patterned pressure against said transfer sheet, from which master sheets multiple copies may be made by pressure against the surface thereof, said process comprising: agitating a mixture of polyhydroxy alcohol, a non-drying oil, and a wax; heating to and maintaining said agitating mixture at approximately 180°, whereby said agitating mixture is rendered completely in the liquid state; adding a kaolinite clay to said agitating mixture; maintaining agitation thereof for at least approximately 15 minutes; slowly sifting a dye soluble therein into said agitating mixture; further agitating said mixture until said soluble dye has completely dissolved in said mixture; grinding said mixture to a particle diameter size of between approximately 0.0002 and 0.0004 inches; and coating said mixture on said transfer sheet surface.
Claim 2
Dependent Claim
148 words
A process for producing a transfer sheet having a transferable coating on said transfer sheet, said transfer sheet for use in producing master sheets by localized, patterned pressure against said transfer sheet, from which master sheets multiple copies may be made by pressure against the surface thereof, said process comprising: agitating a mixture of polyhydroxy alcohol, a non-drying oil, and a wax; heating to and maintaining said agitating mixture at approximately 180°, whereby said agitating mixture is rendered completely in the liquid state; adding a kaolinite clay to said agitating mixture; maintaining agitation thereof for at least approximately 15 minutes; slowly sifting a dye soluble therein into said agitating mixture; further agitating said mixture until said soluble dye has completely dissolved in said mixture; grinding said mixture to a particle diameter size of between approximately 0.0002 and 0.0004 inches; and coating said mixture on said transfer sheet surface.
Claim 3
Dependent Claim
31 words
The method as claimed in claim 1 wherein: said mixture is coated onto a transfer sheet surface at a coating weight of between approximately 2.80 and 3.00 grams per square foot.
