Abstract
Abstract A method of decalcomania in which a toner image pattern is formed on a transfer member which has been overcoated with an abhesive material. A polymeric sheet is interposed between the toner image and a cloth or other image receiving medium. The polymeric sheet assists in the permanent adherence of the toner imaging pattern to the cloth material or other medium when the composite is subjected to heat and pressure. The transfer member and method of its use are set forth. Another embodiment discloses the use of solvent to fix the image to a cloth material.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
68 words
A method of decalcomania comprising xerographically providing a toner image resting on an abhesive substrate, overlaying said image with an interposed sheet of polymeric plasticizing material, placing an image receiving medium in contact with said interposed sheet and applying heat and pressure to the composite formed by said image receiving medium, interposed sheet and said image bearing substrate to form a permanent image on said image receiving medium.
Claim 2
Independent Claim
68 words
A method of decalcomania comprising xerographically providing a toner image resting on an abhesive substrate, overlaying said image with an interposed sheet of polymeric plasticizing material, placing an image receiving medium in contact with said interposed sheet and applying heat and pressure to the composite formed by said image receiving medium, interposed sheet and said image bearing substrate to form a permanent image on said image receiving medium.
Claim 3
Dependent Claim
12 words
The method of claim 1 wherein said image receiving medium comprises cloth.
Claim 4
Dependent Claim
36 words
The method of claim 2 wherein said interposed sheet comprises a polymeric material selected from the group consisting of methacrylate-n-butylmethacrylate copolymers, polyvinyl acetate homopolymer emulsions, vinyl chloride homopolymer latexes, vinyl chloride acrylate latexes and combinations thereof.
Claim 5
Dependent Claim
18 words
The method of claim 2 wherein said cloth is selected from materials of cotton, polyester and blends thereof.
Claim 6
Dependent Claim
23 words
The method of claim 1 wherein said toner image pattern is in full color formed by sequential developing with toners of three colors.
Claim 7
Dependent Claim
11 words
The method of claim 1 wherein said interposed sheet is transparent.
Claim 8
Dependent Claim
25 words
The method of claim 1 wherein the interposed sheet is applied to the toner image on an abhesive coated support to create an integral composite.
Claim 9
Dependent Claim
13 words
The method of claim 1 wherein said interposed sheet further comprises a colorant.
Claim 10
Dependent Claim
12 words
The method of claim 1 wherein said medium comprises a polymeric sheet.
Claim 11
Independent Claim
62 words
A method of decalcomania comprising xerographically forming an image pattern of toner, transferring said toner to an image receiving medium and passing said medium bearing said toner image under a heated roll to which has been applied plasticizer for the toner material in order to apply said plasticizer from said roll to said toner material to fix said image to said medium.
Claim 12
Independent Claim
62 words
A method of decalcomania comprising xerographically forming an image pattern of toner, transferring said toner to an image receiving medium and passing said medium bearing said toner image under a heated roll to which has been applied plasticizer for the toner material in order to apply said plasticizer from said roll to said toner material to fix said image to said medium.
Claim 13
Dependent Claim
37 words
A method of claim 10 wherein said plasticizing material is selected from the group consisting of esters, paraffins, phenoxy plasticizers, phthalate acid derivatives, oleates, stearates and mixtures of these materials and said image receiving medium is cloth.
Claim 14
Dependent Claim
22 words
The method of claim 10 wherein said plasticizing material is a low molecular weight polyethylene and said image receiving medium is cloth.
Claim 15
Dependent Claim
14 words
The method of claim 10 wherein said roller is maintained at about 375° F.
Claim 16
Independent Claim
41 words
A method of decalcomania comprising xerographically forming an image pattern of toner, transferring said toner to an image receiving member, overlaying said toner with a polymeric plasticizing sheet and applying heat and pressure to permanently transfer said image to said member.
Claim 17
Independent Claim
41 words
A method of decalcomania comprising xerographically forming an image pattern of toner, transferring said toner to an image receiving member, overlaying said toner with a polymeric plasticizing sheet and applying heat and pressure to permanently transfer said image to said member.
Claim 18
Dependent Claim
10 words
The method of claim 14 wherein said member comprises cloth.
Claim 19
Dependent Claim
12 words
The method of claim 14 wherein said member comprises a polymeric sheet.
