Abstract
A multi-colored synthetic resin sheet having an upper surface, a lower surface and a uniformly colored longitudinal cross-section which has at least two longitudinally adjacent different colors, with the boundary portion between the colors being in a gradated state on the upper surface and throughout a transversal section of sheet, is formed by adjacently feeding at least two differently colored polymerizable liquids into a polymerizing apparatus and polymerizing and hardening the materials.
Claims26
A multi-colored synthetic resin sheet having an upper surface, a lower surface, and a uniformly colored longitudinal cross-section, which has at least two longitudinally adjacent different colors with a boundary portion therein between, with the boundary portion between said colors being in a gradated state on the upper surface, on the lower surface and throughout a transversal cross-section of said sheet.
A method of producing a multi-colored synthetic resin sheet which comprises:
- adjacently feeding onto a moving belt at least two differently colored liquids comprising polymerizable monomer;
- polymerizing and hardening said liquids;
- thereby obtaining a multi-colored synthetic resin sheet which has an upper surface, a lower surface, and a uniformly colored longitudinal cross-section, which has at least two longitudinally adjacent colors with the boundary portion between said colors being in a gradated state on the upper surface, on the lower surface, and throughout a transversal cross-section of said sheet.
