We claim the ornamental design for a synthetic resin sheet, as shown and described.
FIG. 1 is a synthetic resin sheet showing our new design. The broken line perimeter surrounding the figure indicates the boundaries of the claim and forms no part thereof;
FIG. 2 is an enlarged detail of the synthetic resin sheet of FIG. 1 showing area 2 circumscribed by broken line within FIG. 1; and,
FIG. 3 is the synthetic resin sheet in an environment of use showing area 3 circumscribed by broken line within FIG. 1. All other parts of the figure represent unclaimed environmental subject matter.
The broken lines in the figures and the thickness of the synthetic resin sheet form no part of the claimed design.
