Abstract

Abstract Cloth, such as cotton, burlap, or canvas, has a photographic emulsion laminated thereto, along with an outer protective film. The composite laminate formed is permanent, and sufficiently firmly affixed to the cloth that the cloth is machine washable without substantial damage or alteration of the laminated image. The method of making the cloth laminated with photographic emulsion comprises applying the photographic emulsion facedown on a protective film, coating with adhesive and applying the cloth, drying the emulsion and cloth and pressing between plates, at least one of which is heated. By dipping the emulsion in a stripping solution prior to applying to the protective film, adherence and permanence of the laminate formed is substantially increased.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 317 words
A method of manufacturing an article comprising a composite of cloth laminated with a photographic emulsion comprising the following steps: (a) photographing an item to be transposed onto said cloth laminate; (b) developing said film to produce a negative and using conventional enlarging technique to produce a positive photographic enlarged print comprising an emulsion bonded to a backing paper; (c) immersing said print in a stripping solution comprising a non-dyeing hair shampoo of low pH factor in an aqueous solution at a temperature of about 85° F. to about 100° F. and a concentration of shampoo of about 0.38% to about 0.75% by volume, whereby tearing of said emulsion is substantially preventable; (d) stripping the emulsion from said backing paper; (e) placing said emulsion on a sheet of protective film and smoothing said emulsion to remove excess stripping solution therefrom; (f) coating said emulsion with a water based adhesive; (g) placing said cloth on said coated emulsion to form a composite; (h) drying said composite with heated forced air; (i) placing said dried composite in press means whereby said cloth surface is exposed to an elevated press temperature; (j) pressing with said press means comprising a heated bottom plate sprayed with a vegetable oil derivative for contacting said cloth surface of said dried composite and a receiving plate for contacting said protective film surface of said dried composite, wherein said bottom plate is heated to a temperature of about 200° F. to about 240° F., said bottom plate and said receiving plate pressing said composite at a pressure of about 7500 psi for a time of about 1 to about 2 seconds; and (k) removing said pressed composite from said press means, whereby permanence of the composite is obtained due to the temperature and composition of the stripping solution and whereby machine washing of the composite is possible without substantial alteration of or damage to the composite.
Claim 2
Independent Claim 317 words
A method of manufacturing an article comprising a composite of cloth laminated with a photographic emulsion comprising the following steps: (a) photographing an item to be transposed onto said cloth laminate; (b) developing said film to produce a negative and using conventional enlarging technique to produce a positive photographic enlarged print comprising an emulsion bonded to a backing paper; (c) immersing said print in a stripping solution comprising a non-dyeing hair shampoo of low pH factor in an aqueous solution at a temperature of about 85° F. to about 100° F. and a concentration of shampoo of about 0.38% to about 0.75% by volume, whereby tearing of said emulsion is substantially preventable; (d) stripping the emulsion from said backing paper; (e) placing said emulsion on a sheet of protective film and smoothing said emulsion to remove excess stripping solution therefrom; (f) coating said emulsion with a water based adhesive; (g) placing said cloth on said coated emulsion to form a composite; (h) drying said composite with heated forced air; (i) placing said dried composite in press means whereby said cloth surface is exposed to an elevated press temperature; (j) pressing with said press means comprising a heated bottom plate sprayed with a vegetable oil derivative for contacting said cloth surface of said dried composite and a receiving plate for contacting said protective film surface of said dried composite, wherein said bottom plate is heated to a temperature of about 200° F. to about 240° F., said bottom plate and said receiving plate pressing said composite at a pressure of about 7500 psi for a time of about 1 to about 2 seconds; and (k) removing said pressed composite from said press means, whereby permanence of the composite is obtained due to the temperature and composition of the stripping solution and whereby machine washing of the composite is possible without substantial alteration of or damage to the composite.
Claim 3
Dependent Claim 18 words
The method of claim 1 wherein said protective film is polyethylene having a thickness of about 0.0005 inch.
Claim 4
Dependent Claim 21 words
The method of claim 2 wherein said cloth is cotton and said article is a T-shirt formed from said pressed composite.
Claim 5
Dependent Claim 24 words
The method of claim 2 wherein said cloth is needlepoint canvas and said pressed composite is sprayed with paint varnish to form said article.
Claim 6
Dependent Claim 24 words
The method of claim 2 wherein said cloth is burlap and said pressed composite is coated with gel and dried to form said article.
Claim 7
Dependent Claim 24 words
The method of claim 1 wherein said heated forced air is heated to a temperature of from about 300° F. to about 500° F.
