ABSTRACT OF THE DISCLOSURE: A synthetic plastics or rubber sheet structure having a surface applied pattern in one or more colours extending thereinto, is produced by applying to the surface of the sheet structure at least one colouring agent capable of undergoing migration through the synthetic plastics material and effecting migration of the colouring agent through the sheet structure in the presence of at least one cross-linkable component until the colouring agent has penetrated to a predetermined depth and cross-linking of the cross-linkable component is initiated thereby to stop further migration of the colouring agent on cross-linking of the cross-linkable component. The invention makes it possible to produce a sheet structure having a visible pattern in accordance with the pattern in which the colouring agents are applied, which may be varied as desired on the surface of the sheet structure. In this way, a design can be produced in the sheet structure with a variable thickness including the possibility that penetration of the pattern right through the sheet structure occurs. The effective life of a product coloured by the process of this invention, which product is for example exposed to heavy wear, is now solely dependent on the effective life of the sheet structure itself and is no longer dependent on the resistance to wear or abrasion of a printed impression or of a transparent covering layer which is applied thereto.
