The invention relates to granite-look reinforced laminar products comprising fibrous material, grinded coloured (semi)cured aminoplast resin based granules and a thermosetting aminoplast resin mixture as matrix, the laminar product having a loss on cure of less than 10 wt.%, and in which laminar product, placed between two removable carrier sheets, a compound is contained consisting of (a) 1 to 25 wt.% of grinded coloured (semi)cured aminoplast resin based granules (having certain density and being 3D distributed in the matrix); (b) 20 to 90 wt.% of a filler containing aminoplast resin mixture; and (c) 5 to 35 wt.% of, at least for 60% chopped, fibrous material (2D-randomly distributed in the compound between two layers of said resin mixture matrix), all percentages indicating the solid material contents of the starting materials, and the total of the percentages in (a), (b) and (c) adding up to 100 wt.%. The invention also relates to a sheet moulding compound (SMC) production process for manufacturing such products and to moulded parts prepared therefrom. |
