Coated films
Disclosed is a coating composition and coated film having the coating composition adhered thereto in which the coating composition comprises particulate filler; binder composition comprising acrylic polymer and ethylene acrylic acid copolymers; non-cross-linking adhesion promoter; and optionally urethane polymer, styrene-acrylic copolymer, or a combination thereof; and wherein cross-linker(s) are substantially absent from the composition; and wherein the coated film has a 45° Gloss (ASTM D2457) of less than 30 or 25 or 20 or 15. The coated film is useful for pressure sensitive labels for thermal transfer ribbon printing labels.
1. A film having a coating composition adhered thereto, wherein the coating composition comprises:
particulate filler;
binder composition comprising acrylic polymer and ethylene acrylic acid copolymers, wherein the ethylene acrylic acid copolymers include ethylene acrylic acid copolymer, ethylene methacrylic acid copolymer, and C 1-6 esters of each, or combinations thereof;
non-cross-linking adhesion promoter; and
optionally urethane polymer, styrene-acrylic copolymer, or a combination thereof, and
wherein cross-linker(s) are substantially absent from the coating composition, and
wherein the film having the coating composition has a 45° Gloss (ASTM D2457) of less than 30.
2. The film of claim 1 , wherein a dry weight of the coating composition is within a range of from 0.50 g/m 2 to 6.0 g/m 2 .
3. The film of claim 1 , wherein an average particle size of the particulate filler is less than 10 μm.
4. The film of claim 1 , wherein the particulate filler is present in the coating composition, on a dry weight basis, within a range from 30 wt % to 75 wt %, based on a total weight of the coating composition.
5. The film of claim 1 , wherein the urethane polymer or the styrene-acrylic copolymer, or the combination thereof, is present in the coating composition, on a dry weight basis, within a range from 5 wt % to 25 wt %, based on a total weight of the coating composition.
6. The film of claim 1 , wherein when the urethane polymer or the styrene-acrylic copolymer, or the combination thereof is present, then the particulate filler is present in the coating composition, on a dry weight basis, within a range from 30 wt % to 55 wt %, based on a total weight of the coating composition.
7. The film of claim 1 , wherein the acrylic polymer is present in the coating composition, on a dry weight basis, within a range from 5 wt % to 35 wt %, based on a total weight of the coating composition.
8. The film of claim 1 , wherein the ethylene acrylic acid copolymer component is an ionomer comprising from 65 wt % to 95 wt % of ethylene derived units and from 5 wt % to 35 wt % acrylic or methacrylic acid, C 1-6 esters of each, or combinations thereof, and a metal ion or ammonia associated therewith.
9. The film of claim 1 , wherein the coating composition comprises, on a dry weight basis, within a range from 0.5 wt % to 10 wt % of the non-crosslinking adhesion promoter, based on a total weight of the coating composition.
10. The film of claim 1 , wherein the non-cross-linking adhesion promoter is selected from a group consisting of ethylenically unsaturated acrylates and C 1-6 esters thereof; and C 1-6 esters derivatives thereof, maleic anhydride grafted polymers, and mixtures thereof.
11. The film of claim 1 , wherein the coating composition is dispersed in water prior to application and organic solvents are substantially absent.
12. The film of claim 1 , further comprising a layer of primer between the coating composition and the film.
13. A label having printing, UV or otherwise, thereon comprising the film having the coating composition of claim 1 .
