Abstract
A write-erase article formed of a substrate coated on one surface with a cured epoxy coating composition, and coated on another surface with an adhesive. The epoxy-coated surface is markable with dry wipe inks without causing permanent discernible distortion of the substrate. The epoxy-coated surface after marking is substantially fully erasable. The article may be adhered via the adhesive to a support.
Claims39
A write-erasable article which comprises a substrate having front and rear surfaces, a substantially non-tacky, non-porous, cured epoxy coating composition on the front surface of the substrate and an adhesive coating on the rear surface of the substrate, wherein said epoxy coating composition comprises the reaction product of at least one epoxy polymer or epoxy precursor, at least one amine crosslinker, and at least one acid catalyst.
A writable-erasable board which comprises a substrate having front and rear surfaces, a substantially non-tacky, non-porous, cured epoxy coating composition on the front surface of the substrate, an adhesive coating on the rear surface of the substrate, and a support attached to the rear surface of the substrate via the adhesive coating, wherein said epoxy coating composition comprises the reaction product of at least one epoxy polymer or epoxy precursor, at least one amine crosslinker, and at least one acid catalyst.
A method of producing a writable-erasable board which comprises forming a substantially non-tacky, non-porous, cured epoxy coating composition on the front surface of a substrate;
- forming an adhesive coating on the rear surface of the substrate;
- and then attaching a support to the rear surface of the substrate via the adhesive coating, wherein said epoxy coating composition comprises the reaction product of at least one epoxy polymer or epoxy precursor, at least one amine crosslinker, and at least one acid catalyst.
