Abstract
Abstract A plastic mass suitable for modelling purposes is disclosed. The mass has the following characteristics: A. IT COMPRISES A FILLER, WHICH MAY BE HYDROPHOBIC OR HYDROPHILIC, A HYDROPHILIC PLASTICIZER, AND A COLORING AGENT WHICH IS CAPABLE OF DILUTION WITH WATER, THE COLORING AGENT BEING A DYESTUFF OR A PIGMENT; B. IT CAN BE DILUTED WITH WATER; C. IN MOIST CONDITION IT RELEASES AND TRANSFERS COLOR UPON CONTACT; D. IT RELEASABLY ADHERES TO SUBSTRATES.

Claim 3
Dependent Claim
58 words
A kneadable coherent mass as claimed in claim 1, wherein said filler is selected from the group consisting of polyvinylchloride, chalk, talcum, bentonite, barium sulfate, alumina and kaolin while said hydrophilic plasticizer is selected from the group consisting of polyethylene glycol, alkali metal salts of fatty acids, alkaline earth metal salts of fatty acids, dextrin, glycerin and methylcellulose.
Claim 4
Dependent Claim
23 words
A kneadable coherent mass as claimed in claim 2, wherein said hydrophilic plasticizer is sodium stearate, potassium soap, calcium oleate or sodium oleate.
Claim 5
Dependent Claim
21 words
A kneadable coherent mass as claimed in claim 1, wherein the coloring agent is a hydrophilic, dispersed pigment or a dyestuff.
Claim 6
Dependent Claim
42 words
A kneadable coherent mass as claimed in claim 4, wherein the pigment is a mono- or diazo pigment of the naphthol series or the sodium or calcium salt thereof, or is a copper phthalo cyanine, while said dyestuff is an aniline dye.
Claim 7
Dependent Claim
25 words
A kneadable coherent mass as claimed in claim 4, wherein the mass additionally contains a dispersing agent for the pigment, said dispersing agent being nonionogenic.
Claim 8
Dependent Claim
34 words
A kneadable coherent mass as claimed in claim 6, wherein the dispersing agent is an alkyl- and/or alkylarylpolyglycolether, the amount of dispersing agent being about 0.5-2 percent by weight calculated on the pigment quantity.
Claim 9
Dependent Claim
20 words
A kneadable coherent mass as claimed in claim 1, wherein the mass also comprises an emulsifier containing a hydrophilic group.
Claim 10
Dependent Claim
33 words
A kneadable coherent mass as claimed in claim 8, wherein the emulsifier is selected from the group consisting of fatty acid amides, poly saccarides, Turkey-red oil, mono fatty acid esters and alkylpolyglycol ethers.
Claim 11
Dependent Claim
23 words
A kneadable coherent mass as claimed in claim 9, wherein the weight ratio of filler to plasticizer is between about 2.5:1 and 7:1.
Claim 12
Dependent Claim
33 words
A kneadable coherent mass as claimed in claim 1, further comprising a binder in the form of an aqueous suspension of synthetic resin particles which are capable of cross-linking upon application of heat.
Claim 13
Dependent Claim
46 words
A kneadable coherent mass as claimed in claim 11, wherein the aqueous suspension comprises between 0.01 to 0.1 percent by weight of the total mass, said aqueous suspension containing water, 15-80 percent by weight of synthetic resin and 0.2-5.0 percent by weight of an organic solvent.
Claim 14
Dependent Claim
21 words
A kneadable coherent mass as claimed in claim 1, which has one of the following five compositions, in parts by weight:
Claim 15
Dependent Claim
50 words
A plastic mass as claimed in claim 11, in combination with a textile substrate to which said mass is adhered, said binder, upon heating of said mass, forming a cross-linked substance which binds the particles of the pigment to each other and said substrate and renders said pigment particles water-insoluble.
Claim 16
Dependent Claim
25 words
A kit comprising a receptacle and a plurality of pieces of the plastic mass of claim 1, each of said pieces having a different color.
Claim 17
Dependent Claim
77 words
A method of forming a multi-colored imprint of a multi-colored object which comprises forming portions of said object by kneading pieces of the plastic mass of claim 1 into desired shapes, at least two of said pieces having different colors, assembling the shapes into the desired object by sticking the pieces together so that one surface of the object is substantially planar, moistening the planar surface and pressing a color-receptive receiving sheet thereon, and removing the sheet.
Claim 18
Dependent Claim
35 words
A kneadable coherent mass as claimed in claim 1, wherein said hydrophilic plasticizer is a liquid which is present in an amount sufficient to render the mass plastic and kneadable without the addition of water.
