Multi-colored synthetic resin sheet

摘要

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.
