    Abstract: A polyester film having a nodule surface is disclosed. The acrylic coating is preferably a crosslinked composition having a relatively high methyl methacrylate content and specific surfactants. The acrylic coating composition is applied as an aqueous dispersion to polyester film, preferably after corona treatment of the polyester film. The nodule surface reduces the coefficient of friction of the polyester film. The coating composition comprises from 60 to 90 mole percent methyl methacrylate; from 10 to 35 mole percent of at least one modifier selected from the group of ethyl acrylate, propyl acrylate, butyl acrylate, and mixtures of these; and from 3 to 10 mole percent of a crosslinkable monomer or a self-crosslinking monomer selected from the group of N-methylol methacrylamide, N-methylol acrylamide, acrylamide, methacrylamide, and mixtures of these; with from 2 to 15 weight percent of the nonionic surfactant and at least 0.1 percent by weight of the anionic surfactant.

    Abstract: The present invention describes a polymeric support film coated with a primer coating composition and overcoated with a silicone release coating, thereby forming a silicone release film. Silicone release films are well known and serve as temporary supports for an adhesive or tacky surface such as for labels, pressure sensitive tape etc. The primer coating composition, before dilution with water, comprises from about 25 to 75% by weight of a glycidoxy silane and from about 75 to 25% by weight of a copolyester. The copolyester comprises from about 65 to 98 mol percent isophthalic acid; from about 0 to about 30 mol percent of at least one aliphatic dicarboxylic acid; from about 2 to about 20 mol percent of at least one sulfonate group attached to a dicarboxylic nucleus; and about 100 mol percent of glycol having from about 2 to 11 carbon atoms. Typical glycidoxy silanes that can be employed in the primer coating composition include glycidoxypropyltrimethoxysilane.

    Abstract: Plastic films having improved antistatic properties are disclosed having a continuous coating on at least one surface of the film based on a composition comprising a mixture of:(a) a polymeric binder, and(b) a quarternary ammonium salt having the formula: ##STR1## wherein: R is a lower alkyl group having 1 to 3 carbon atoms;R' is an alkyl or alkenyl radical having from about 8 to 20 carbon atoms; andX.sup.- is an anion.The antistat coating composition may be applied to the film material at any suitable stage during manufacture, i.e., after extrusion of the sheet material or before, during or after orienting the sheet. The resultant film is found to possess markedly enhanced antistat properties, good clarity, good slip properties, reclaimability and adhesive properties at higher binder levels rendering it suitable for the application of other coatings.
