Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
105 words
A composite laminate forming a geometric image wherein said laminate comprises a substrate having adhered thereon a flexible foil comprising a clear plastic having a grooved surface on its underside, said grooves being from about 5×10 -5 to 25×10 -3 of an inch apart and coated with a thin layer of light reflecting material of a thickness of between 0.5×10 -6 and 1×10 -6 inches, said foil being capable of dispersing and reflecting visible light into its component colors; and an overlying non-reflective layer adhered to the other side of said foil opposite said grooves which, in conjunction with the foil, produces the desired image.
