Abstract
The present invention relates to a coating composition for polyester film capable of printing on all types of printers with liquid and dry toners. The coating composition comprising of a combination of polyethylene carboxylic acid dispersion and homopolymer or copolymer of polyacrylate dispersion and/or homopolymer or copolymer of polyvinyl acetate dispersion, wherein acrylate and/or acetate content be is in the range of 1 to 50% of carboxylic acid content in the dispersion.
Claims14
A coating composition for applying on a polyester film to form a coating capable of being printed on by all types of electrostatic printers, wherein the coating composition comprising:
- a dispersion mixture comprising:
- (i) a polyethylene carboxylic acid polymer dispersion comprising an ethylene acrylic acid copolymer, wherein the ethylene carboxylic acid polymer has an acrylic acid content in the range of 10 to 30 wt %;
- and
- (ii) at least one second polymer dispersion selected from a polyacrylate homopolymer or copolymer dispersion and/or a polyvinyl acetate homopolymer or copolymer dispersion;
- wherein the ethylene acrylic acid copolymer is in the range of 10 to 90 wt %, based on the total weight of the dispersion mixture;
- wherein the polyacrylate polymer content and/or the polyvinyl acetate polymer content is in the range of 2 to 40 wt % of the ethylene acrylic acid copolymer content in the dispersion mixture;
- and
- wherein the dispersion mixture represents 100% of the coating composition.
