Abstract
This article contains meltable and/or heat-curable synthetic resin as binder and from 5 to 50% by weight, based on the total quantity of resinous binder and pigment, of at least one colouring pigment. A pulverulent mixture is formed from the components of the article and this is pressed to form the article at below the softening or curing temperature, for example at room temperature. With this article, shaped in the manner of sticks of chalk, pictures can be produced which can be permanently fixed by the application of heat. Since this requires only temperatures up to about 200 DEG C, the fixing can be achieved with simple means, for example on a hot plate or in an oven.
