Abstract

PURPOSE:To distribute fine pigment particles uniformly into a resin base material and to improve productivity by preparing a resin-pigment mixture with a melt kneading stage using a specific intermeshed twin-screw melt extruder and laminating the mixture by a melt extrusion-coating method. CONSTITUTION:The length L of respective screws 11, 12 of the intermeshed twin-screws 10 with respect to the diameter D thereof has a relation L>=20D and at least one set of kneading disks 13 are provided to at least one point of the screws 10 at the time of laminating the mixture contg. the water resistant thermosetting resin and pigment on at least one face of a sheet-shaped base body by the melt extrusion-coating method. The intermeshed twin-screw extruder 1 is used. The resin-pigment mixture is prepd. with at least one time of the melt kneading stage. The base is thereby produced with high productivity and high working efficiency and a high dispersion effect is obtd.
