Resin sheet for transmissive screen

A process for producing an extruded resin sheet (A), comprising:

• extruding a thermoplastic resin from a die (1) in a heat melt state,
• nipping the resin in between a first cooling roll (R1) and a second cooling roll (R2), winding the resin on the second cooling roll (R2), and then
• winding the resin on one lattercooling roll (R3), or winding the resin on a plurality of lattercooling rolls (R3, R4 . . . ) one after another to cool the resin, and then
• further cooling the resin while maintaining the resin in a flat state to solidify, and subsequently
• withdrawing the resin by means of a pair of take-off rolls (N1, N2), wherein
• the peripheral speed (V3) of the one lattercooling roll (R3) or the average peripheral speed (V3a) of the plurality of the lattercooling rolls (R3, R4 . . . ) is made to be 0.94 times to 1.03 times the average peripheral speed (V12) of the first cooling roll (R1) and the second cooling roll (R2),
• the average peripheral speed (Vn) of the pair of the take-off rolls (N1, N2) is made to be 0.95 times to 1.03 times the peripheral speed (V3)of the one lattercooling roll (R3) or the average peripheral speed (V3a) of the plurality of the lattercooling rolls (R3, R4 . . . ), and
• the average peripheral speed (Vn) of the pair of the take-off rolls (N1, N2) is made to be 0.95 times to 0.995 times the average peripheral speed (V12) of the first cooling roll (R1) and the second cooling roll (R2).
