ABSTRACT:
A process is disclosed for forming decorated articles of acrylic resins, more particularly acrylic sheets bearing figures and inscriptions, according to which a molding cell, having one of its inner faces coated with a coloured paint reproducing the desired inscriptions or decorations, is filled with an acrylic prepolymer in admixture with a polymerization catalysts, the polymerization is carried out in a controlled temperature environment until the polymer is still ductile, and then the polymer mass incorporating the coloured paint coating is placed in a second molding cell of greater inner size, the space remaining between the outer surfaces of the polymer mass and the inner faces of said second cell is filled with additional mixture of acrylic prepolymer and catalysts, and then the polymerization process is completed under controlled temperature, whereby the required figures or inscriptions are incorporated in the acrylic body.
