DE2265000B2 - PLASTIC MEASURES FOR PLAY, EDUCATION AND TEACHING PURPOSES - Google Patents

Description

The invention relates to a plastic mass for play, Instructional and teaching purposes or the like, consisting of fillers, binders, plasticizers and dyes consists. With the main patent it is proposed, inter alia, that the mass for the production of colored and ink-releasing images, dyes emulsifiable in water and a hydrophilic plasticizer contains. This mass can be modeled and can change its color through contact when it is wet transferred to an ink receptive agent such as a sheet of paper or fabric. By using a hydrophilic plasticizer, the mass is water-absorbing.

With the help of such a mass, completely new areas of application for a playing child, a Artists etc. opened up. In the plastic state, this mass can initially be used to produce Shapes, figures and the like can be used. It is also able to absorb water and can use it give off paint when wet. One can proceed in such a way that masses of different colors are deformed and a flat cake or a similar structure is created, the flat surface of which is composed of masses of different colors. If you moisten this flatbread or the one towards it laying means and one puts this means, z. B. a piece of paper or a piece of fabric, on the flatbread, so will Transfer the image created with the flatbread onto the paper, the fabric or the like. So you can get a bigger one Make number of impressions. Once a flatbread has been formed, it can be set aside and stored for as long as you like will. But it can also be broken down into its individual masses of a certain color and these can be used for Formation of new moldings or flatbreads can be reused. The mass can be diluted with water. she can therefore serve for painting after moistening by z. B. by means of a brush or your finger the damp Part of the mass decreases and applies to the surface to be painted. This gives the playing child the artist, the artistically active layman, etc. new, interesting and versatile design possibilities given in hand.

The disadvantage of the mass according to the main patent was that they were involved in the agent, e.g. B. a textile, not remained inextricably attached, but can be washed out of it again. The object of the invention is therefore to improve a mass according to the teaching of the main patent so that the on a means released color is fixable. This fixation should also be feasible by children.

To solve this problem, the invention proposes that a further binder be added is that by heating the mass, the dye pigments in connection with a carrier, preferably a Textile fabric that makes it insoluble in water. As a further binder can also be a self Crosslinking, copolymeric dispersion are used. This has the advantage that one according to the invention of the main patent from such a mass to one

ίο Fix a piece of fabric or the like. d. H. can make water-insoluble. Otherwise there would be the risk or the disadvantage that with one If a fabric that has been printed or dyed in this way becomes damp, the ink that has been transferred to it will be smeared or is returned. The heating can e.g. B. in an oven or with the help of an iron take place. Instead of one textile, another one, printed or dyed according to the invention, could also be used Carrier should be treated in this way, provided that it is able to withstand the temperature.

The invention is preferably carried out with a composition that has such a large proportion of hydrophilic Plasticizer has that the mass is plastic even without the addition of water, i. H. remains kneadable.

Further details and exemplary embodiments of the proposed mass are given below.

As a further binder proposed by the invention for fixing the released color a suspension of synthetic resin particles (15 - 80%) in water with the addition of of organic solvents (0.2-5%) in an amount of 0.01 -01% of the total mass. This Binder binds the pigment particles to one another and to the carrier under the influence of heat, preferably a textile fabric, and thus forms a water-insoluble surface.

The plasticizer can, for. B. be: polyethylene glycol, fatty acids of the alkali and alkaline earth metals such as sodium stearate, potassium soap and calcium oleate.

Dextrin, glycerine can also be used as plasticizers and methyl cellulose, preferably a liquid plasticizer such as glycerine or polyglycol ether can be used. This not only gives the desired one Plasticity, but also facilitates the inclusion of

Humidity.

The filler can be hydrophobic (e.g. polyvinyl chloride). A hydrophilic filler is also possible, z. B. chalk, lime, bentonite, barium sulfate, clay and kaolin.

As a hydrophilic highly disperse pigment z. B. mono- and diazo pigments of the naphthol series, their sodium or calcium salts, copper phthalocyanine and other organic pigments are used. One with Spreading agent mixed with these pigments can be a non-ionic product in the proportion of preferably 0.5-2% to the pigment mass. A mixture of alkyl and Alkylaryl polyglycol ethers are used.

An emulsifier can be added to the pigment

be muddled. Such pigment dyes mix particularly well with the inter alia. preferred as filler used polyvinyl chloride. The addition of an emulsifier with a hydrophilic group is used especially the dilutability of the mass when adding moisture, preferably water. As emulsifiers The following can be used: fatty acid amides, polysaccharides, Turkish red oil, monofatty acid esters, alkyl polyglycol ethers etc.

To the examples given below, which are preferred embodiments of the invention are to be seen, it is also pointed out that in order to achieve good plasticity, a ratio of The filler for the plasticizer, preferably in the range of 2.5: 1, is shown to be particularly favorable Has. In this connection it should be noted that some plasticizers, such as sodium oleate or dextrin, some of which have a filler function.
