Abstract
A decorative object comprising an acrylic glass support plate and differently colored polymethyl methacrylate layers and zones thereupon, on one or both major surfaces of the plate, differently colored zones and vertically superposed layers of polymethyl methacrylate being separated from each other and from the support plate by barrier elements and layers respectively which are optically and mechanically compatible with but completely insoluble in and unpenetrable by polymethyl methacrylate.
Claims15
A decorative object comprising
- a. a transparent support plate of polymethyl methacrylate, bearing at least on one surface,
- b. at least one decorative layer of polymethyl methacrylate coated on said support and consisting of horizontally separated zones of different colors,
- c. at least two transparent colorless vertical-barrier layer coatings of a cross-linked polymethyl methacrylate based composition, insoluble in monomeric and polymeric methyl methacrylate, the first layer being disposed between said support and said decorative layer and the second layer on the upper surface of said decorative layer, and
- d. horizontal-barrier elements consisting of strips cut from thermoplastic polyester sheets, said elements being fixed to said support plate by said first vertical-barrier layer and separating said horizontally adjacent differently colored zones of said decorative layer.

A decorative object comprising
- a. a transparent support plate of polymethyl methacrylate, bearing at least on one surface
- b. a first decorative layer of polymethyl methacrylate coated on said support and consisting of horizontally separated zones of different colors,
- c. at least two transparent colorless vertical barrier layer coatings of a cross-linked polymethyl methacrylate based composition, insoluble in monomeric and polymeric methyl methacrylate, the first layer being disposed between said support and said first decorative layer and the second layer on the upper surface of said first decorative layer,
- d. horizontal-barrier elements consisting of strips cut from thermoplastic polyester sheets, said elements being fixed to said support plate by said first vertical-barrier and separating said horizontally different colored zones of said decorative layer,
- e. a second decorative layer having horizontally adjacent zones of different colors coated on said second transparent colorless vertical-barrier layer which color zones are separated from each other by horizontal barrier elements consisting of strips cut from thermoplastic sheets fixed to said second transparent colorless vertical-barrier layer,
- f. a third transparent colorless vertical-barrier layer coated on the upper surface of said second decorative layer and horizontal-barrier elements, said layer being a cross-linked polymethyl methacrylate based composition insoluble in monomeric and polymeric methyl methacrylate.

A method for manufacturing a decorative object, comprising the steps of
- a. providing a biplanar transparent support plate of polymethyl methacrylate,
- b. pouring thereon a solvent free liquid composition comprising monomeric methyl methacrylate with polymethyl methacrylate dissolved therein, a polyfunctional ester of methacyrlic acid, and a catlayst,
- c. curing said liquid composition at a temperature in the range of 15.degree. to 40.degree.C during 5 to 24 hours,
- d. placing on the surface of the cured liquid composition strips cut from a thin thermoplastic polyester sheet,
- e. fixing said strips by brushing with said liquid composition, and curing it,
- f. filling the horizontal spatial zones between said strips with a decorative composition comprising a solvent-free monomeric methyl methacrylate with polymethyl methacrylate dissolved therein, a catalyst and, if desired, a dyestuff or pigment,
- g. hardening said decorative composition at a termperature in the range of 15.degree. to 40.degree.C during 5 to 24 hours,
- h. pouring another liquid composition as in step (b) onto said hardened decorative composition, and
- i. curing this composition.
