The top coat composition comprises a base part which comprises 35-45 parts by weight of an acrylic resin, 0.1-1 parts by weight of a dispersant, 35-45 parts by weight of a heat insulating pigment, 0.1-1 an antisettling agent, 0.1-1 parts by weight of a catalyst and 5-15 parts by weight of a polyester resin; and a curing agent part which comprises 40-50 parts by weight of a polyisocyanate, 0.1-1 parts by weight of a water absorber and 50-60 parts by weight of a diluent.
