## Abstract

The present invention relates to a coated film comprising a polyester film and a coating layer provided on one side thereof, which coating layer is formed by applying a coating solution containing at least one binder resin (A), a polycarbodiimide compound (B) and a melamine compound (C).

## Claims

### Claim 1

A coated film comprising a polyester film and a coating layer provided on one side thereof and having a thickness of 0.003 to 0.3 μm, wherein said coating layer is formed by applying an aqueous solution or a water dispersion containing at least one binder resin (A) selected from polyester resins, acrylic resins, and polyurethane resin; a polycarbodiimide compound (B); and a melamine compound (C); and wherein the coating layer contains organic particles, inorganic particles, or a mixture thereof.

### Claim 2 (depends on 1)

A coated film according to claim 1, wherein each of said binder resin (A), polycarbodiimide compound (B) and melamine compound (C) is water soluble or water-dispersible.

### Claim 3 (depends on 1)

A coated film according to claim 1, wherein the coating layer is formed by applying a coating solution containing the coating layer composing components (A), (B) and (C) on a film, then drying and stretching the film.

### Claim 4 (depends on 1)

A coated film according to claim 1, wherein the ratios of the binder resin (A), polycarbodiimide compound (B) and melamine compound (C) in the coating solution are 100 parts by weight: 0.2 to 50 parts by weight: 0.2 to 50 parts by weight.

### Claim 5 (depends on 1)

A coated film according to claim 1, wherein the organic particles and inorganic particles have an average particle size of 0.005 to 5.0 μm.

### Claim 6 (depends on 1)

A coated film according to claim 1, wherein the content of particles in the polyester film is 0.001 to 30.0% by weight.
