TITLE: Method for the fabrication of articles cast from highly filled resins
having a surface with regions of different colours.
European Patent EP0526818
 B1

ABSTRACT:
Abstract of EP0526818
The invention relates to a process for fabricating polymer mouldings
having differently coloured surface regions from casting resins, in
which a surface of the shaping mould, before filling with the casting
resin, is coated with a curable coating of a colorant-containing
composition in such a manner that different colours result, the coating
being applied in at least two coating operations onto the surface
regions of the mould intended for this by applying in the first coating
operation a filler-containing coating dispersion L-1 without the
addition of colorant and applying in the second coating operation a
filler-free colorant-containing coating L-2 and, after drying of the
coats, filling the mould with the casting resin and polymerising the
latter by heating and subsequently removing the moulding.
