Abstract
A laminar coating material, for example for use as flooring, comprises: a polyolefin matrix having a first colouring; and a phase of particulate elastomer material, such as vulcanized rubber, dispersed in the polyolefin matrix and comprising particles of at least one second colouring, which contrasts with the colouring of the polyolefin matrix. Preferably, the particulate elastomer material in question is in turn obtained starting from a plurality of intermediate mixes, each comprising a polyolefin matrix having a first colouring, in which there is dispersed a respective particulate phase comprising particles of a respective second colouring. The respective second colouring is different for each intermediate mix and contrasts with the aforesaid first colouring. The intermediate mixes are mixed together so as to form a mixture used for obtaining the final material, preferably by means of granulation, formation of a bed of granules, and isostatic pressing of the bed thus formed.
