The present invention provides solid preparations having two or more colors or a pattern of two or more different colors which can solve the problems of the prior art including the complexity of production processes and the low strength of solid preparations. Specifically, an object of the present invention is to provide solid preparations coated with a continuous film coating layer having two or more different colors or a pattern of two or more different colors which preparations are obtained by irradiating a part of the film coating layer containing one or more colorants with light, a process for the preparation of such solid preparations, and a film coating agent therefor. The present invention also provides a solid preparation treating apparatus for yielding a continuous film coating layer on the surface of a solid preparation with two or more different colors or a pattern of two or more different colors, which comprises a solid preparation loader movably disposed, a light controller for controlling the light-exposed surface area of the solid preparation and a light source for light irradiation.
