Abstract
Multilayer graphic articles include a graphic substrate, and an overlaminate film laminated to the graphic substrate. The overlaminate film includes a transparent film layer with a fluorochemical-containing acid-resistant layer coated on at least a portion of one surface, and an adhesive layer coated on at least a portion of the opposite surface of the transparent film. The transparent film layer may be a vinyl film layer. The acid resistant layer includes a blend of at least one fluoropolymer and at least one acrylate resin.
Claims20
An article comprising:
- a graphic substrate;
- and
- an overlaminate film laminated to the graphic substrate, the overlaminate film comprising:
- a transparent film layer comprising a first major surface and a second major surface;
- a fluorochemical-containing acid-resistant layer coated on at least a portion of the first major surface of the transparent film, wherein the acid resistant layer comprises a blend of at least one fluoropolymer and at least one acrylate resin;
- and
- an adhesive layer coated on at least a portion of the second major surface of the transparent film, wherein the overlaminate film has an elongation at room temperature of at least 50%.
A method of preparing a graphic article comprising:
- providing a graphic substrate;
- providing an overlaminate film wherein the overlaminate film comprises:
- a transparent film layer comprising a first major surface and a second major surface;
- an acid-resistant layer coated on at least a portion of the first major surface of the transparent film, wherein the acid resistant layer comprises a blend of at least one fluoropolymer and at least one acrylate resin;
- and
- an adhesive layer coated on at least a portion of the second major surface of the transparent film, wherein the overlaminate film has an elongation at room temperature of at least 50%;
- and
- laminating the overlaminate film to the graphic substrate to form a graphic article.
