초록 ▼

A primer coating is provided for use on polymeric substrates to enhance adhesion of liquid toner to the substrates for printing in an electrophotographic printing device. The primer coating is water-based and includes a dispersion of a copolymer of ethylene and acrylic or methacrylic acid, and a compatible adhesion enhancer selected from an aliphatic polyurethane dispersion, a hydrogenated hydrocarbon rosin or rosin ester dispersion, and an amorphous acrylic polymer dispersion. The coating may also include additives such as wetting agents, antiblocking agents, matting agents, and waxes. The primer coating may be applied to a variety of polymeric substrates including polypropylene, biaxially oriented polpypropylene, polyethylene terephthalate, and polyvinyl chloride.

대표청구항 ▼

The invention claimed is: 1. A coated polymeric substrate having first and second major surfaces, said substrate being selected from polypropylene, biaxially oriented polypropylene, polyethylene terephthalate, polyamide, biaxially oriented polyamide and polyvinyl chloride, with at least one of said major surfaces having coated thereon a primer coating for enhancing adhesion of liquid toner thereto, said coating comprising a mixture of a copolymer of ethylene and acrylic or methacrylic acid; an adhesion enhancer selected from the group consisting of an aliphatic polyurethane, a hydrogenated hydrocarbon rosin or rosin ester, and an amorphous acrylic polymer; and an antiblocking agent comprising a metal hydroxide. 2. The coated substrate of claim 1 wherein said at least one major surface of said polymer substrate has been treated by a flame treatment or corona discharge treatment prior to applying said primer coating thereto. 3. The coated substrate of claim 1 wherein said primer coating is about 0.3 to about 2 microns thick. 4. The coated substrate of claim 1 wherein said primer coating is from about 0.5 to about 1 microns thick.
