Abstract
The invention relates to the use of a coating comprising at least one fatty-acid modified resin as an anti-fingerprint coating on a least one face of a glass sheet. In particular, the invention allows to provide an anti-fingerprint solution to be used for a glass sheet, which does not significantly affect the surface properties and the aesthetics of the coated glass compared to the naked glass. Moreover, the invention allows to provide an anti-fingerprint solution to be used for a glass sheet, which is sustainable in time and/or wearing of the surface.
Claims12
A coating comprising at least one fatty acid-modified resin, wherein:
- the coating is arranged as an anti-fingerprint coating on at least one face of a glass sheet, and
- said fatty acid modified resin is a resin which has been structurally modified by grafted fatty acid functional groups, wherein said fatty acid functional groups are carboxylate ester functional groups with a long alkyl chain, which is either saturated or mono or poly unsaturated, conjugated or not, branched or not.
A method, comprising applying a coating to at least one face of a glass sheet, wherein:
- the coating comprises at least one fatty-acid modified resin,
- said fatty acid modified resin is a resin which has been structurally modified by grafted fatty acid functional groups, and
- said fatty acid functional groups are carboxylate ester functional groups with a long alkyl chain, which is either saturated or mono or poly unsaturated, conjugated or not, branched or not.
