Abstract
An architectural panel produced by forming a raised or depressed pattern in the surface of a base plate and sprinkling and sticking particulate material to both or either of the depressions and protrusions to provide the architectural panel with an excellent three-dimensional effect by virtue of the combined effect of the pattern and the particulate material. According to one form of the invention, an architectural panel having an excellent three-dimensional effect and massiveness is produced by using a metallic base plate and overcoming the feeling of smoothness and lightness peculiar to metallic material with the combined effect of such pattern and particulate material. According to another form of the invention, an architectural panel is produced by applying a base coat layer and/or an overcoat layer to a base plate to provide an excellent design quality and protection against fall-off of the particulate material.
