PROBLEM TO BE SOLVED: To provide the reflective type projection screen handily usable for meetings and lectures and yet functionable as a white board. SOLUTION: This projection screen is formed by laminating a reflective layer 2, a density control layer 3, a flare preventive layer 4, a nonglare layer 5, and a top coat layer 6 on a support 1. The top coat layer 6 is formed by mixing 5-10 pts.wt. of a block copolymer having fluoroalkyl groups with 100 pts.wt. of an acrylurethane resin, and coating the nonglare layer 5 with this obtained resin composition in a thickness of 2-30μm by use of a gravure coating machine.
