Embodiment 10

[0092]Examples 10-12 give a typical ink receiving layer formulation including pigment, UV and antiblocking additives. This formulation has good ink receptivity after preparation (Example 10), after heat aging (Example 11) and after exposure to intense UV ink curing conditions (Example 12).

Embodiment 16

[0094] Example 16 and Comparative Example 15C are two extreme examples, illustrating that Elvaloy TM The effect of 741 terpolymer to promote ink acceptance. UV ink has difficulty adhering to Surlyn 1705-1 ionomer (comparative example 15C), but blended with appropriate amount of Elvaloy TM 741 terpolymer (Example 16), Surlyn 1705-1 ionomer was also an effective ink receiver, albeit at the expense of blend physical properties.

[0095] Results comparable to Examples 9-12 were obtained when Chevron SP1305 ethylene methyl acrylate resin was used in place of Bynel 3101 resin.

[0096] The above data show the effect of ethylene-vinyl acetate-carbon monoxide terpolymer on ink viscosity. While not wishing to be bound by a particular theory, it is believed that the increased polarity of these materials renders them effective as ink acceptors, and that the oxygen functionality of the carbon monoxide, in part, provides active sites for the UV curable inks.

Abstract

An image receptor medium including an image reception layer having two major opposing surfaces. The image reception layer comprises a terpolymer of ethylene vinyl acetate carbon monoxide, optionally blended with at least one other polymer that can be wherein the image reception layer further comprises at least one other polymer blended with the terpolymer, wherein the other polymer is selected from the group consisting of ethylene vinyl acetate resins, ethylene (meth)acrylic acid copolymer resins, polyethylene resins, polypropylene resins, ionomers, acid-modified or acid / acrylate modified ethylene vinyl acetates and a polymer comprising at least two monoethylenically unsaturated monomeric units, wherein one monomeric unit comprises a substituted alkene where each branch comprises from 1 to about 8 carbon atoms and wherein one other monomeric unit comprises a (meth)acrylic acid ester of a nontertiary alkyl alcohol in which the alkyl group contains from 1 to about 12 carbon atoms and can include heteroatoms in the alkyl chain and in which the alcohol can be linear, branched, or cyclic in nature, and combinations of such other polymers thereof. Alternatively, the image receptor medium includes a substrate layer comprising a polymer substrate layer having two major opposing surfaces and an image reception layer on a first major surface of the substrate layer. The image reception layer has an outer surface for receiving images, and comprises a terpolymer identified above. Either embodiment of the image receptor medium may further include an optional prime layer, an optional adhesive layer, and an optional inkjet layer.

Description

field of invention [0001] This invention relates to films useful as image receptor media suitable for use with various imaging materials such as inks and toners. background of the invention [0002] Advertising and promotional displays often include images on structural surfaces (such as car bodies and awnings) or hanging objects (such as flags). In preparing such displays, the image is applied to an adhesive-backed image-receiving medium (sometimes referred to as an image-marking film), which is subsequently adhered to the desired substrate. Alternatively, the image is first produced on a temporary carrier (ie, image transfer medium) and subsequently transferred to an image receptor medium. Image receptor media generally include a substrate and an additional receptor layer overlying it. The substrate is usually a plastic polyvinyl chloride film, although paper can also be used. [0003] Outdoor storage periods are usually relatively short (3 months to 1 year), although i...
