It is an object of the present invention to provide a coating with both primer and base coating function for an inmold decoration product, which can attain an inmold decoration product which secures adequately the adhesion between a polyolefin substrate and a coating film layer without forming a primer coating film layer and also has excellent properties in a precipitating property of silver, smoothness of a silver-plating layer and coating film appearance, a method of producing inmold decoration products formed by using this base coating composition and an inmold decoration product. A coating with both primer and base coating function for an inmold decoration product, used in a method of producing inmold decoration products obtained by forming a multilayer coating film comprising a silver-plating layer, said multilayer coating film being obtainable by forming a coating film layer with both primer and base coating function, a silver-plating layer and a top clear coating film layer on a polyolefin substrate, wherein said coating with both primer and base coating function comprises a main material (a) based on acrylic polyol (a1), a chlorinated polyolefin modified acrylic resin (a2) and a chlorinated polyolefin resin (a3), and a polyisocyanate curing agent (b), the % by weight of the solids of said (a1), (a2) and (a3) are 40 to 80%, 5 to 45% and 1 to 35%, respectively, and the main material (a) contains cyclohexane in an amount 5 to 45 parts by weight per 100 parts by weight of the solids in the main material.
