<P>PROBLEM TO BE SOLVED: To obtain a reflection plate which is low-cost and has good light reflectivity and workability. <P>SOLUTION: A white resin coating which has a refractive index of ≥1.7 and contains 70 to 150 pts.mass of white pigment having an average primary particle size of 100 to 1,000 nm, to 100 pts.mass of resin is formed on a chemical conversion coating on at least one face of a metallic plate having chemical conversion coatings on both faces. It is preferable that a ratio of particles having ≥400 nm primary particle size to all particles in the white pigment is ≤40% and particles of the white pigment are made of one or more kinds of rutile-type titanium dioxides and anatase-type titanium dioxides and have surfaces subjected to surface treatment by one or more kinds of alumina, silica, titania, and zirconia. Preferably, a heat-dissipating resin coating or a heat-dissipating conductive resin coating is formed on the other face to make a heat-dissipating face or a heat-dissipating conductive face. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
