I claim the ornamental design for a printed cooling material, as shown and described.
FIG. 1 is a front view of a printed cooling material, showing my new design;
FIG. 2 is a back view thereof;
FIG. 3 is a top view thereof;
FIG. 4 is a bottom view thereof;
FIG. 5 is a right side view thereof;
FIG. 6 is a left side view thereof;
FIG. 7 is a cross-sectional view thereof; and,
FIG. 8 is a perspective view thereof.
The claim is directed to the oval elements drawn in solid lines and the areas within these elements arranged vertically and horizontally on a square sheet. The broken lines representing the back and the depth of the design represent unclaimed portions of the printed cooling material and form no part of the claimed design.
Biocompatible perforated membranes, processes for their preparation, their use as a support in the in vitro growth of epithelial cells, the artificial skin obtained in this manner, and its use in skin grafts
