ABSTRACT:
A colored acrylic sheet having an attractive 3-dimensional depth of color resulting from the use of a mixture of pigments or a pigment and a dye wherein an inorganic pigment, distributed non-uniformly throughout the sheet and a colorant is distributed uniformly through the sheet, the particles of non-uniformly distributed pigment being concentrated preferentially towards one surface of the sheet and are visible through the opposite surface of the sheet which is preferably substantially free from the non-uniformly distributed pigment. The attractive appearance is further enhanced by shaping the sheet and the sheet is particularly suitable for forming articles of sanitaryware.
