PROBLEM TO BE SOLVED: To provide a resin composition affording a molded product having low-thermal storage properties and a woodgrain pattern with excellent weather resistance, woodgrain coloring properties, heat resistance, etc. SOLUTION: The low-thermal storage resin composition comprises 100 pts.mass of pellets of a composition (I) composed of a rubber-reinforced vinylic resin, an inorganic pigment having infrared light reflection characteristics and a lubricant and 0.1-30 pts.mass of pellets of a composition (II) composed of a thermoplastic resin, a dye or a pigment and a lubricant. The amounts of the inorganic pigment and the lubricant are 0.5-13 mass% and 1-12 mass% based on the whole composition, respectively. The temperature rise obtained under the test conditions is≤73°C. [test conditions] A molded product (80 mm length, 55 mm width and 2.5 mm thickness) composed of the low-thermal storage resin composition is conditioned in a room regulated to 25±2°C temperature and 50±5% RH humidity for 60 min and the surface is then irradiated with an infrared lamp (100 W output) from 200 mm height for 60 min. The surface temperature of the molded product is subsequently measured and the difference from the initial temperature before the irradiation with the infrared lamp is taken as the temperature rise.
