PROBLEM TO BE SOLVED: To provide a top coat composition of a curable acrylic resin which, when coated on the surface of a form panel for concrete and the like, enables the form panel to be released easily from the hardened concrete and allows the same form panel to be repeatedly used in many times, and to provide the form panel for concrete obtained by coating the composition. SOLUTION: The top coat composition of the curable acrylic resin (C) for the concrete form panel contains a curable, hydroxyl group containing acrylic resin (i), a polysiloxane compound (vi), and an isocyanate curing agent (iv). On the surface of a base panel, a filling coating film (A) comprising a curable acrylic resin composition of a specific composition, a middle coat coating film (B) comprising a curable acrylic resin composition different from the above, and a top coat clear coating film (C) comprising the above composition (C) are formed in the order of the above-mentioned [base panel/film (A)/film (B)/film (C)] to form the concrete form panel. Its manufacturing method is also provided. COPYRIGHT: (C)2005,JPO&NCIPI
