Abstract
Abstract A supporting structure for a decalcomania wherein the decalcomania is inserted into an aqueous solution prepared by adding a reagent to water or into a quantity of mixed aqueous solution prepared by dissolving a reagent in a quantity of suitable solvent and then mixing this solution with a quantity of water and wherein a coating (6, 3A) of a water soluble separating agent is applied over the decalcomania and wherein the dissolving speed of the coat (6, 3A) is selected to be in accordance with the reaction speed of a coloration reactant or a chromogenic substance such as a dye previously added to the coating (6, 3A) of the water soluble separating agent such that a color change will be visually present when the optimum time for transfer of the decalcomania occurs.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
81 words
A supporting structure for a decalcomania adapted for use with a color developing solution of predetermined temperature comprising a supporting sheet having a coating of a water soluble separating agent thereon in which there is dispersed an inorganic color forming compound which reacts with said color developing solution to generate a color, the concentration of inorganic compound being such that said color is generated at approximately the time that said water soluble separating agent is dissolved in said color forming solution.
Claim 2
Dependent Claim
81 words
A supporting structure for a decalcomania adapted for use with a color developing solution of predetermined temperature comprising a supporting sheet having a coating of a water soluble separating agent thereon in which there is dispersed an inorganic color forming compound which reacts with said color developing solution to generate a color, the concentration of inorganic compound being such that said color is generated at approximately the time that said water soluble separating agent is dissolved in said color forming solution.
Claim 3
Dependent Claim
15 words
A supporting structure according to claim 1 in which said water-soluble separating agent includes dextrine.
Claim 4
Dependent Claim
32 words
A supporting structure according to claim 1 in which said surface includes a dextrine layer containing said color forming inorganic compound, and a second dextrine layer devoid of said color forming compound.
Claim 5
Dependent Claim
16 words
A supporting structure according to claim 1 wherein said inorganic color forming compound is aluminum sulfate.
Claim 6
Dependent Claim
36 words
A supporting structure for a decalcomania according to claim 1 which includes a printed ink layer over said surface, a transparent resin layer over said ink layer, and a layer of adhesive over said resin layer.
Claim 7
Dependent Claim
35 words
A supporting structure for a decalcomania according to claim 5 wherein said transparent resin layer has a surface layer area larger than the surface of the printed ink layer so as to completely surround it.
