PURPOSE:To obtain a plate colored in different tints of depth either having a linear pattern extending to the inside of a boardlike article from the surface of the same or showing a gradating state on a boundry of the linear pattern, by a method wherein polymerizing liquid raw materials having at least two kinds of different colors are made to cure through polymerization by pouring the same into a polymerizer. Through at least two groups of ducts and, moreover, outlets of the ducts are arranged by combining them alternately. CONSTITUTION:Polymerizing liquid raw materials whose colors are different from each other are poured through inlets A, B, C at a predetermined ratio through a fixed delivery pump. A liquid A of the polymerizing liquid raw materials poured through the inlet A passes through a discharge openign group shown by the discharge opening 1. A liquid B is distributed into a radial groove through a groove 4 in a circumferential direction and passes through a discharge opening group 2 provided in the groove. A liquid C passes through a discharge opening group 3 provided in the radial groove through a groove 4' in the circumferential direction. The liquids A-C are combined with each other and poured into a polymerizer through a discharge opening D by constituting a linear pattern. |
