Summary: | PROBLEM TO BE SOLVED: To provide a film exhbiting favorable beauty of glazing and securing both high mechanical and chemical durability having favorable durability to thermal treatment (annealing, toughening, bending folding).SOLUTION: A transparent substrate (6) is composed of a thin laminate (A) continuously having a first layer (1) having a refractive index nof 1.8 to 2.3 and a geometric thickness of 5 to 50 nm, a second layer (2) having a refractive index nof 1.35 to 1.65 and a geometric thickness eof 5 to 50 nm, a third layer (3) having a refractive index nof 1.8 to 2.3 and a geometric thickness eof 40 to 150 nm, and a fourth layer (4) having a refractive index nof 1.35 to 1.65 and a geometric thickness eof 40 to 150 nm. |
