Abstract

PURPOSE: A polyester film colored blue usable for X-ray photograph, having a desirable color, comprising Color Index Solvent Blue 97 as a colorant having improved heat resistance and compatibility.
CONSTITUTION: 50W1000ppm, preferably 100W500ppm, of Color Index Solvent Blue 97 is incorporated into a polyester. The colorant is added during the polyester preparation, mixed with pellets before molding, or during the extrusion step. If the amount of the colorant is ≤50 ppm, the coloring effect is insufficient. If the amount is ≥1,000 ppm, the transparency of the film is lowered and the color is dark, scarcely transmitting light.
