Abstract
An acrylic laminated diffuser panel having a high light-diffusing property is provided, which comprises a laminate of an acrylic resin film having a high light-diffusing property and an acrylic resin plate, wherein the acrylic resin film is integrated with the acrylic resin plate. The acrylic laminated diffuser panel is prepared by laminating the acrylic resin film on the molding surface of at least one of a pair of casting mold parts, casting an acrylic monomer or its partially polymerized product into a space between said pair of casting mold parts, and then, polymerizing the acrylic monomer or the partially polymerized product.

A process for the preparation of acrylic laminated diffuser panels having a high light-diffusing property, which process comprises the successive steps of:
- (1) laminating an acrylic resin, particle-containing film having a high light-diffusing property onto the molding surface of at least one of a pair of casting mold parts, wherein said light diffusing particles are incorporated in an amount such that the parallel ray percent transmission of the finished acrylic diffuser panel is not greater than about 60%,
- (2) casting an acrylic monomer or its partially polymerized product into a space between said pair of casting mold parts, and then,
- (3) polymerizing said acrylic monomer of said partially polymerized product, thereby causing the acrylic resin film to become integrated with and laminated onto the resulting acrylic resin plate.
A process for the preparation of acrylic laminated diffuser panels having a high light-diffusing property, which process comprises the successive steps of:
- (1) laminating an acrylic resin film having a high light-diffusing property containing particles of the order of 1 to 100 microns therein on the molding surface of at least one of a pair of casting mold parts, wherein said particles diffuse light and are incorporated in an amount such that the parallel ray percent transmission of the finished acrylic diffuser panel is not greater than about 60%,
- (2) casting an acrylic monomer or its partially polymerized product into a space between said pair of casting mold parts, and then,
- (3) polymerizing said acrylic monomer or said partially polymerized product, thereby causing the acrylic resin to become integrated with and laminated onto the resulting acrylic resin plate.
