Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
75 words
A method of forming a thermally imageable colored image on a substrate comprising the steps of (a) forming a latent liquid image on a substrate; and (b) contacting said liquid image with a thermally imageable toner powder of particles comprising at least 50 weight percent of a supercoolable material, at least 0.01 weight percent of a colorant, up to 20 weight percent of a binder and up to 40 weight percent of an anti-fouling agent.
Claim 2
Independent Claim
75 words
A method of forming a thermally imageable colored image on a substrate comprising the steps of (a) forming a latent liquid image on a substrate; and (b) contacting said liquid image with a thermally imageable toner powder of particles comprising at least 50 weight percent of a supercoolable material, at least 0.01 weight percent of a colorant, up to 20 weight percent of a binder and up to 40 weight percent of an anti-fouling agent.
Claim 3
Independent Claim
145 words
A method of forming a multicolored image on a substrate comprising the steps of (a) providing a substrate capable of forming or receiving a latent liquid image thereon; (b) providing a first said latent liquid image on said substrate; (c) developing said first latent liquid image by applying thereto a first thermally imageable toner powder of particles comprising at least 50 weight percent of a supercoolable material, at least 0.01 weight percent of a colorant, up to 20 weight percent of a binder and up to 40 weight percent of an antifouling agent; (d) allowing said first latent liquid image to solidify; (e) forming a second latent liquid image on said substrate so that at least a portion of said second latent liquid image is on said first toner powder; (f) developing said second latent image by applying thereto a second toner powder of particles.
Claim 4
Independent Claim
145 words
A method of forming a multicolored image on a substrate comprising the steps of (a) providing a substrate capable of forming or receiving a latent liquid image thereon; (b) providing a first said latent liquid image on said substrate; (c) developing said first latent liquid image by applying thereto a first thermally imageable toner powder of particles comprising at least 50 weight percent of a supercoolable material, at least 0.01 weight percent of a colorant, up to 20 weight percent of a binder and up to 40 weight percent of an antifouling agent; (d) allowing said first latent liquid image to solidify; (e) forming a second latent liquid image on said substrate so that at least a portion of said second latent liquid image is on said first toner powder; (f) developing said second latent image by applying thereto a second toner powder of particles.
Claim 5
Dependent Claim
27 words
A method of claim 1 or 2 wherein said substrate bears a coating of a supercoolable material which forms said latent liquid image when exposed to heat.
Claim 6
Dependent Claim
17 words
A method according to claim 2 wherein said first and second toner powders are of different colors.
Claim 7
Dependent Claim
19 words
A method according to claim 1 further comprising the step of solidifying said latent liquid image after said contacting.
Claim 8
Dependent Claim
22 words
A method according to claim 2 further comprising the step of solidifying said first latent liquid image after it has been developed.
Claim 9
Dependent Claim
22 words
A method according to claim 6 further comprising the step of solidifying said second latent liquid image after it has been developed.
