摘要 <p>Disclosed is a base film for protective films which is excellent in solvent resistance and heat resistance during heating, while having low birefringence. Also disclosed is a protective film covered polarizing plate which is provided with such a film. Specifically disclosed is a base film (10) for protective films which is composed of a three-layer non-oriented film obtained by arranging a polyester film (9) on both sides of a polycarbonate film (8).
