Kodak made and sold one instant film, PR-10, produced in the late 70s. It was heavier than the Polaroid instants and plastic in feel. It had a matte surface with rounded corners and a black back. It was discontinued by Kodak when Polaroid won the lawsuit contending that Kodak had infringed their patents. Kodak was ruled to have done so inadvertantly and to have worked diligently to avoid Polaroid patents and so the damages awarded were only about equivalent to royalties on the patents. Damages were not trebled for malicious intent.

That ended Kodak's entire foray into instant.
