Abstract
The present invention provides a novel silicone free copolymer and coating prepared therefrom. The coating which is capable of being written on effectively with both solvent-based and water-based inks is also bleedthrough resistant. A repositionable pressure sensitive adhesive note is capable of effectively adhering to the coating. The invention also provides substrates coated with the coatings and articles such as pads and rolls formed from the coated substrates.
